What We Calibrate

Calibration Services Overview

⚖️

Load Cell Calibration

Multi-point calibration of all load cell types from 10 N to 2000 kN against traceable reference standards.

🔧

Torque Sensor Calibration

Static and dynamic torque calibration from 0.1 Nm to 5000 Nm. Both clockwise and counter-clockwise.

🔴

Pressure Sensor Calibration

Hydraulic and pneumatic pressure calibration from 0 to 10,000 PSI with traceable deadweight testers.

🏭

Testing Machine Verification

Verification of UTMs and material testing machines per IS 1828 / ISO 7500 standards.

🔩

Torque Wrench Calibration

Calibration and verification of manual and hydraulic torque wrenches per ISO 6789.

📍

On-Site Calibration

For large or installed instruments that cannot be transported, we offer on-site calibration at your facility.

Our Process

Calibration Process

01

Intake & Inspection

Visual inspection, condition assessment, and documentation of the instrument's identification and history.

02

Pre-Calibration Testing

As-found measurements at multiple points to document the instrument's current deviation from standard.

03

Adjustment (If Required)

If the instrument is outside tolerance, adjustment is performed and documented. Not all instruments require or allow adjustment.

04

Post-Calibration Verification

Full multi-point calibration with loading and unloading cycles. Measurement uncertainty calculated per GUM.

05

Certificate Generation

Detailed calibration certificate with as-found/as-left data, uncertainty statement, traceability, and environmental conditions.

Frequently Asked Questions

Standard calibration turnaround is 3-5 working days from receipt of instruments. Express calibration (1-2 days) is available at additional cost for urgent requirements.
JRAGRAU provides NABL-traceable calibration through our accredited laboratory partners. We also issue in-house calibration certificates with documented traceability to NPL India standards.
Yes. We calibrate load cells, torque sensors, and pressure sensors from any manufacturer, provided we have or can obtain the technical specifications.
Our calibration process follows IS 4169 / ISO 376 for force-proving instruments, IS 1828 / ISO 7500 for testing machines, and ISO 6789 for torque tools. Uncertainty is calculated per GUM (Guide to Expression of Uncertainty in Measurement).
Yes. We can set up a calibration schedule for your entire instrument inventory and send proactive reminders when instruments are due. This helps maintain continuous ISO 9001 compliance.
Every certificate includes: instrument identification, as-found and as-left readings, measurement uncertainty with coverage factor, traceability statement, environmental conditions, reference standard used, and pass/fail status against your specified tolerance.
