Product Introduction
The Digital Negative Pressure Gauge is a high-precision, multi-functional standard instrument developed by our company for on-site pressure gauge calibration. It features pressure measurement capabilities and, when used in conjunction with a handheld pressure pump, allows for the field calibration of pressure (differential pressure) transmitters, pressure switches, and general (precision) pressure gauges.
Product Features
◆ Compact size, suitable for confined spaces;
Micro-power consumption components selected, long outdoor working time.
Through a 4-digit digital display:Advanced software processing technology continuously corrects for non-linearity and temperature drift.
For verification:General Pressure Gauges; Calibration of Precision Pressure Gauges; Calibration of Blood Pressure Meters; Calibration of Other Pressure Instruments; Precision Pressure Measurement; Analysis of Precision Pressure Changes; Precision Pressure Control.
