Every measurement your workshop trusts, traced back to national standard.
Precise Caltest is Ahmedabad's NABL accredited calibration laboratory for dimensional, mechanical, thermal and electro-technical instruments — from vernier calipers to torque wrenches, backed by an unbroken chain of traceability.
One laboratory, eight measurement disciplines.
From a hand-held vernier caliper to a bench-mounted profile projector, each instrument is calibrated against reference standards maintained under controlled temperature, humidity and light.
Mechanical Dimension
Calipers, micrometers, height gauges, plug & ring gauges, slip gauges, protractors and 30+ related instruments.
Pressure Indicating Devices
Analogue and digital pressure gauges calibrated across your working range with certified deadweight and pneumatic standards.
Torque Generating Devices
Torque wrenches and drivers verified for accuracy at the settings you actually use on the shop floor.
Temperature
Infrared thermometers and temperature indicators, calibrated with traceable reference probes.
Electrical & Electronic
Clamp meters, multimeters, vibration meters, lux meters and stopwatches, checked against certified electronic standards.
Acoustics, Speed & Density
Sound level meters, tachometers and viscosity cups — plus repair & reconditioning for worn instruments.
Traceability is a chain — we protect every link in it.
Every reading we issue can be walked back, comparison by comparison, to a national measurement standard. That chain is what an auditor is really asking about when they ask for your calibration certificate.
National Standard
Maintained by the national metrology institute.
Reference Masters
Precise Caltest's own master instruments, calibrated at accredited labs.
Working Standards
Used daily in our environmentally controlled laboratory.
Your Instrument
Calibrated, certified, and ready to go back to work.
Built for the auditor as much as the engineer.
Accredited, not self-declared
Our scope is assessed and recognised under NABL, so your quality system has documented evidence, not just our word.
Controlled environment
Temperature, humidity and light intensity are monitored to the standards your instruments actually need.
Repairs, not just rejections
Instruments found out of tolerance can often be repaired and re-certified in-house, instead of simply failed.
