ECO 2 from Keller is a compact and economical digital pressure measuring instrument providing 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 pressure is measured twice per second and displayed. The top display indicates the actual pressure, the bottom display shows the Max.- or Min.- pressure since the last RESET.
ECO 2 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.- and Min.-value. ECO 2 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. Process pressure connection is G 1/4" male.
