Product Description
Series HM35 Digital Absolute Pressure Manometer – 0–29 psia, Model HM3531ALJ300
The Series HM35 digital absolute pressure manometer is engineered for laboratories, calibration facilities, and industrial verification programs that require accurate low-range absolute pressure measurement with traceable documentation. Covering a 0–29 psia range with a ±0.20% full-scale accuracy tier, this model supports absolute-pressure testing while capturing real-time system behavior through integrated data logging and graphical trend display.
Each instrument ships with a calibration certificate, enabling it to function as a dependable secondary calibration reference for validating pressure transmitters, regulators, vacuum systems, and controlled-environment instrumentation.
