Sound familiar?
Spreadsheets and Word templates work until the lab grows, an assessor asks for records, or a customer calls for a certificate from last year.
Calibration management software replaces that patchwork with one system for the whole job: customer and equipment records, service requests, readings, measurement uncertainty, review, certificates and recalibration reminders. Every step is recorded, so the record an assessor asks for already exists.
It is built for calibration labs in India: NABL-accredited labs, labs preparing for accreditation, and biomedical service companies that calibrate hospital equipment in the lab and on site.
How it works
Each step hands over to the next, so nothing is retyped and nothing is lost between people.
Step 1
Pick the customer and their equipment, and raise a Service Request Form for in-lab or on-site work, with challan, PO and photos attached.
Step 2
The job goes to an engineer and a reviewing technical manager, and its status is tracked from start to finish.
Step 3
Engineers enter test-point readings on the template for that instrument type, with the environmental conditions. Minimum repeat readings are enforced.
Step 4
Error, measurement uncertainty and the Pass / Fail decision are calculated per test point, against your decision rule.
Step 5
A different person reviews and approves. Results lock once they go to review.
Step 6
The PDF certificate is generated with your logo and signatories, a gap-free number, the ULR where it applies, and a QR code.
Step 7
Before the due date the customer gets a reminder and can book recalibration from their portal.
Features
Grouped the way your lab works, not the way a software menu is laid out.
Leads and customers, and an equipment register with make, model, group, sub-group, serial number and lab ID. SRFs and delivery challans as PDF. Bring in old equipment lists and past certificates by CSV.
A calibration template for each instrument type, with its test points. Readings, repeat readings and environmental conditions are captured with every calibration.
Type A repeatability, resolution, the reference standard’s certificate uncertainty and accuracy specification, combined and expanded uncertainty with coverage factor k, using Welch–Satterthwaite effective degrees of freedom.
Deviation is worked out per test point and checked against permissible error limits, with “Not Evaluated” where no limit applies. A manual override needs a written reason and is logged.
A master register with each standard’s certificate, specification, uncertainty and traceability. Expired or untraceable standards are blocked automatically, with alerts before they expire.
The engineer who calibrated cannot approve. Branded PDF certificates with uncertainty and k, controlled re-issue with a reason (the old PDF is kept), and e-mail to the customer from the system.
Certificate number schemes you configure, ULR generation that never skips or repeats, separate NABL and non-NABL handling, and a QR code linking to an online verification page.
Open and overdue jobs, turnaround time, certificates issued, conformity rate, equipment due, standards expiring and pending approvals. Reports export to Excel by Indian financial year.
Your product name, logo, colours, login page and footer. Reminder schedules, e-mail wording, numbering formats and file types are admin settings, not developer work.
Compliance
The software does not accredit your lab; NABL accredits laboratories, not software. What it does is keep the records and controls an assessor looks for, as part of normal daily work.
| What the standard asks for | How the software handles it |
|---|---|
| Equipment and metrological traceability (ISO/IEC 17025, clauses 6.4 and 6.5) | A register of reference standards with certificates and traceability. A standard that has expired or is not traceable cannot be used on a job. |
| Evaluation of measurement uncertainty (clause 7.6) | Uncertainty is calculated from its components for every test point and reported with the coverage factor k. |
| Technical records (clause 7.5) | Each result keeps a calculation snapshot: readings, reference values, standards used, formula and uncertainty components. An issued result can be reproduced even if master data changes later. |
| Statements of conformity and decision rule (clause 7.8.6) | Pass / Fail is decided against permissible limits by your decision rule. An override needs a reason and is logged. |
| Amendments to issued reports (clause 7.8.8) | A certificate is re-issued only as a controlled revision with a reason. The original PDF is kept. |
| Control of data and information (clause 7.11) | A change history of every edit to jobs, readings, results, standards, certificates and customers: who, when, before and after. It can be exported for an assessment. |
| Review and authorisation of results | The engineer who performed a calibration cannot review or approve it, and results lock once they go to review. |
| NABL certificate numbering | ULR numbers and certificate numbers are generated without gaps or duplicates, with NABL and non-NABL work kept apart. |
Results are rounded only at the reporting stage, never in between, so the reported figures match the calculation.
Instruments
Templates are in place for the instruments biomedical calibration labs handle every week, in the lab and on site. These are examples, not the full limit.
Repeat business
Missed due dates are lost recalibration work. The software reminds your customers before their equipment is due, and makes it easy for them to book again.
Security and backups
Every change to jobs, readings, results, standards, certificates and customers, with who, when, and the before and after values. Visible to the administrator and exportable.
View, create, edit, delete and approve rights per module, so each person sees and does only what their role needs.
Daily and weekly database backups from the admin panel, password-protected downloads, failure alerts, and off-site copies to Google Drive or Amazon S3.
Secure file handling, protection against forged requests, and each customer limited to their own records.
Side by side
| Excel, Word and registers | Calibration Management Software | |
|---|---|---|
| Measurement uncertainty | Formulas in a sheet, copied from job to job | Calculated per test point, with k and degrees of freedom |
| Certificate and ULR numbers | Typed by hand; gaps and repeats happen | Generated automatically, gap-free and duplicate-free |
| Expired reference standards | Someone has to remember to check | Blocked from use, with alerts before expiry |
| Who changed what | Not recorded | Full change history with before and after values |
| Review and approval | Often the same person | Engineer and approver always different people |
| Certificate copies for customers | Phone calls and e-mails to your office | Customer portal and online QR verification |
| Due-date follow-up | A list someone may or may not check | Automatic reminders and online rebooking |
| Backups | One PC, maybe a pen drive | Daily and weekly backups, with off-site copies |
Who it is for
Keep records assessment-ready every day, not just in the weeks before a visit.
Start with the controls ISO/IEC 17025 expects already built into how you work.
Calibrate hospital equipment in the lab and on site, and keep each hospital’s certificates and due dates in order.
Assign jobs, separate engineers from reviewers, and see workload and turnaround at a glance.
Coming soon
These are planned, not part of the software today.
Add-on
Record expenses with receipts, link them to jobs and customers, and approve them through a flow where nobody approves their own claim. Expense reports included.
Works in the browser on desktop and tablet, in light or dark mode.
Pricing
Pricing depends on the size of your lab and the modules you need. Book a short demo, tell us how many certificates you issue, and we will share the figures in writing.

It is software that runs a calibration lab’s work in one place: customers and their equipment, service requests, readings, measurement uncertainty, review, certificates and recalibration reminders, with a record of every step.
No, and no software can be. NABL accredits laboratories, not software. This software is built around NABL and ISO/IEC 17025 practice and helps your lab keep the records and controls assessors look for, but accreditation always depends on your lab.
From its components at each test point: Type A repeatability from your readings, resolution, the reference standard’s certificate uncertainty and accuracy specification. These are combined, and the expanded uncertainty is reported with coverage factor k based on Welch–Satterthwaite effective degrees of freedom.
Yes. ULR and certificate numbers are generated automatically to the scheme you configure, without gaps or duplicates, and NABL and non-NABL work are handled separately.
Yes. Every certificate carries a QR code that opens an online verification page, so anyone can check that the certificate is genuine.
Yes. A Service Request Form can be raised for in-lab or on-site service, and the job, readings and certificate follow the same flow either way.
Yes. The admin panel runs daily and weekly database backups with retention, password-protected downloads and failure alerts, and can keep off-site copies on Google Drive or Amazon S3.
Yes. Certificates carry your logo and signatories, and the software itself can carry your name, logo, colours and login page.
It is web-based and works in the browser on desktop and tablet, so there is nothing to install on each computer.
Yes. Equipment lists and past certificates can be imported in bulk from CSV files.
