Description
The Master Pressure Gauge by Aavad Instrument Pvt. Ltd. — also known as a Test Gauge or Reference Gauge — is a high-precision calibration-grade pressure instrument designed for calibrating field pressure gauges, transmitters, and other measurement instruments in ISO 9000-compliant calibration laboratories and quality control departments. With an industry-leading accuracy of ±0.25% of Full Scale Deflection (FSD), this master pressure gauge sets the reference standard for pressure verification, instrument testing, and metrology applications where repeatability and precision are non-negotiable.
Engineered with a 150 mm mirror-scale dial, knife-edge micro-zero pointer, and SS 316 Bourdon tube, this test gauge minimizes parallax error and enables fine zero-point adjustment for laboratory-grade calibration accuracy. The IP-65 rated SS 304 enclosure, neoprene blow-out disc, and plain glass window combine to deliver a robust yet precise instrument suitable for both bench calibration and field test-gauge applications.
