Pressure Indicator PCE-DMM 20

The pressure indicator PCE-DMM 20 has a two-line display. The pressure indicator can represent pressures up to 600 bar, relative or absolute. The parts of the pressure indicator PCE-DMM 20 that can come into contact with liquid are made of stainless steel. As a result, the indicator is used, for example, for water testing and laboratory technology. The housing of the pressure indicator can be rotated, so that even under difficult conditions the display is easy to read. The digital pressure indicator is powered by two 1/2 AA lithium batteries. These ensure a standby period of up to 1.5 years. In addition to the display of the current measured value, the pressure indicator can store the maximum and minimum measured value. To preserve battery life, the display turns off after a time set by the user.
