BIS-compliant metrology services

Precision calibration & independent auditing

Absolute error curves for analog differential pressure transducers, shielded thermocouples, and industrial manometers.

Our verification process follows Bureau of Indian Standards protocols, delivering traceable calibration certificates with full uncertainty calculations for every instrument tested.

Trusted by Industry Leaders

Our calibration and auditing services are relied upon by top manufacturing and processing facilities across India for their precision and compliance with BIS protocols.

★★★★★ 4.9/5 Precision Calibration for Critical Systems

“Lifepulses calibrated our entire suite of differential pressure transducers. The error curves were spot-on, and the BIS compliance documentation saved us during a surprise audit. Exceptional work.”

★★★★★ 4.8/5 Thermocouple Verification Excellence

“We had our shielded thermocouples independently audited by Lifepulses. Their drift analysis revealed a recurring issue we had missed for months. The detailed report was invaluable for our quality team.”

★★★★★ 4.9/5 Manometer Audit & Compliance

“The manometer calibration service is thorough. They tested hysteresis and full-scale accuracy on all our liquid-filled units. The audit report helped us achieve ISO 9001 recertification without any non-conformities.”

★★★★★ 5.0/5 Reliable Partner for Harsh Environments

“Our chemical processing plant operates in extreme conditions. Lifepulses’ shielded thermocouple verification package gave us confidence in our temperature readings. Their technicians are knowledgeable and professional.”

★★★★★ 4.7/5 Independent Auditing You Can Trust

“We needed an unbiased third-party audit for our pressure measurement systems. Lifepulses delivered a clear, actionable report with absolute error curves. No fluff, just data. Highly recommend.”

Frequently Asked Questions

Common queries about our calibration, verification, and auditing services for industrial pressure and temperature instruments.

What is the typical turnaround time for a differential pressure transducer calibration?

Standard calibration takes 3 to 5 business days from receipt of the instrument. Rush orders can be completed in 48 hours for an additional fee. The final report includes the absolute error curve and BIS compliance certificate.

Do you provide on-site calibration for shielded thermocouples?

Yes, we offer on-site verification for type K, J, and T shielded thermocouples. Our technician brings NIST-traceable references and performs cold-junction compensation and insulation resistance tests at your facility. Travel charges apply outside a 50 km radius from our base.

Which BIS standards do you follow for manometer auditing?

We follow IS 3624 for liquid-filled manometers and IS 13421 for digital manometers. Each audit report includes a full hysteresis test, zero-point drift check, and a deviation table against the specified accuracy class.

Can you calibrate transducers with non-standard pressure ranges?

Yes, we handle custom ranges up to 400 bar. The multi-point pressure application is adjusted to cover the full operating span of your transducer. Contact us with the model number and range to confirm feasibility.

What documentation do I receive after a calibration service?

You receive a detailed calibration certificate with traceability data, uncertainty calculations, and the absolute error curve. For auditing services, we also provide a separate compliance report with recommendations for recalibration intervals.

How often should industrial manometers be recalibrated?

We recommend recalibration every 12 months for manometers in continuous use. For instruments exposed to extreme temperatures, vibration, or corrosive media, a 6-month interval is advised. Our audit report includes a specific recommendation based on your operating conditions.

One audit covers all analog differential pressure transducers, shielded thermocouples, and industrial manometers in your facility. BIS-compliant error curves included.
