The Keller ECO2301/4NPT Digital Pressure Gauge, 1/4NPT, -1 to 30 Bar is a compact and economical digital gauge that provides medium accuracy at high resolution and repeatability. The piezoresistive pressure transducer as the heart of the instrument has gone through extensive pressure- and temperature tests.
The ECO2301/4NPT is available in two pressure ranges: -1 to 30 bar or 0 to 300 bar, each with a standard accuracy of ±0.5% FS. Pressure can be displayed as bar, mbar/hPa, kPa, MPa, PSI, kp/cm2. The pressure is measured twice per second and displayed. The top of the two-line display indicates the actual pressure while the bottom display shows the maximum or minimum pressure since the last reset.
The ECO2301/4NPT has two operating keys. The left key turns on the instrument and is used to select the functions and the pressure units. The right key executes the selected function or unit. The right key is also used to switch between the Max/Min value.
The Keller ECO2 has 7/16" UNF male thread and is delivered complete with an O-ring seal swivel fitting which allows ECO 2 to be rotated 360°. Only minimal torque is needed to seal up to 300 bar. A G 1/4" male adapter is included.
