GNW210 Digital Reference Pressure Gauge

The GNW210 is a high-accuracy digital reference pressure gauge designed for calibration, pressure comparison and instrument verification work. Available measuring ranges extend from -1 to 0 bar vacuum through to 0 to 1600 bar, allowing the gauge to be selected for a wide range of pneumatic and hydraulic pressure applications.

The dual 5-digit LCD provides clear numerical indication, while the ±0.05% full-scale accuracy supports demanding reference measurement tasks. The gauge can be powered by three AA batteries or through its USB connection.

Available bottom-entry process connections include 1/2-inch BSP, 1/4-inch BSP and 1/4-inch NPT. The case, bezel and wetted parts are manufactured from 304 stainless steel for use with compatible pressure media.

Select a range that comfortably covers the maximum test pressure while providing suitable resolution for the instrument being checked.
