Product Description
Series HM35 Ultra-Precision Digital Absolute Pressure Manometer – 0–108 psia, Model HM3531ALK600
The Series HM35 ultra-precision digital absolute pressure manometer is engineered for laboratories, calibration facilities, and industrial verification programs that demand high-accuracy absolute pressure measurement with traceable documentation. Covering a 0–108 psia range with a ±0.10% 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, process systems, and controlled-environment instrumentation.
