What is Calibration? Full Guide for Industrial Users
What is Calibration?
Why is Calibration Important in Industry?
| Benefit | Impact |
|---|---|
| Accuracy | Ensures measurements are within acceptable limits |
| Compliance | Meets ISO 9001, NABL, FDA, and other standards |
| Product Quality | Maintains consistency and safety in production |
| Audit Readiness | Required for internal and third-party audits |
| Cost Savings | Prevents rework, waste, and customer returns |

How to Choose the Right Calibrator
| Criteria | What to Consider |
|---|---|
| Measurement Type | Temperature, Humidity, Voltage, etc. |
| Application | Lab-based or field-use? |
| Accuracy Requirement | As per your process tolerance |
| Device Compatibility | RTDs, TCs, mA loops, digital meters |
| Compliance Need | NABL/ISO calibration standards |
PRO Tips from Sansel Experts
- Calibrate before & after major maintenance
- Always use NABL-traceable reference standards
- Keep a digital calibration log or sticker system
- Allow instruments to stabilize before taking readings
- Recalibrate based on frequency: every 6–12 months or as per SOP
Calibration Frequency (Industry Best Practice)
| Industry | Calibration Interval |
|---|---|
| Pharma & Food | Every 3–6 months |
| Manufacturing | Yearly (12 months) |
| Labs & R&D | As per internal SOPs |
