DPM 950

3 ? Digit LCD Module

Very low current consumption results in a long battery life and makes the DPM 950 ideal for portable equipment. For low light viewing,

a long life LED backlight is fitted. The meter is housed in a robust carrier which can be bolted in place or panel mounted using the bezel,

window and clips provided.
