The Keller ECO 2 is a compact and economic digital pressure measuring instrument, available for liquid, or as an intrinsically safe (IS/Ex/ATEX) version for air and gas. It is of medium accuracy, but of high resolution and repeatability.
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 is to turn the instrument on and to execute its functions (the functions appear successively on the display as long as the key is pressed and are executed when releasing the key). The right key is also used to switch between the MAX.- and MIN.-value.
