Dwyer 490A-6-HKIT(0-200 PSI) HYDRONIC DIFFERENTIAL PRESSURE MANOMETER

Description

SERIES 490A HYDRONIC DIFFERENTIAL PRESSURE MANOMETER
Liquid & Gas Pressure Measurement, ±0.5% FS Accuracy
The Series 490A Hydronic Differential Pressure Manometers are versatile, handheld, battery operated manometers available in several basic ranges for positive or positive differential pressure measurement and can tolerate most liquid media compatible with 316LSS. A new feature added to the Series 490A is a field adjustable damping, which allows the user to choose the level of display averaging rate corresponding to the fluctuation level common in many applications.

Hydronic meter kit includes: (2) six foot high-pressure rated tubing with shut off valves, high pressure 3-way valve, 8 ft poly tubing for purges, hard travel case, handheld carrying strap, 1/16″ x 1 1/2″, 1/8″ x 3″ and 1/8″ x 1-1/2″ pairs of pressure probes, 90° Flare to 1/4″ NPT fittings, adjustable 8″ wrench, PTFE Tape, and magnetic protective rubber boot. NIST Calibration Certificate comes standard.
