PTDU Portable Temperature Display Unit

Guard Level® 07324 PTDU Portable Temperature Display Unit

Features & Benefits:

The Portable Temperature Display Unit (PTDU) is designed to work in conjunction with the Bergan-Blue Barge Cargo Temperature Unit (BCTU 1 per tank).

The PTDU (1 per barge) is used to read temperature from the Barge Cargo Temperature Unit installed in each tank. The PTDU allows accurate cargo temperature readings by barge personnel without hand dipping tank or exposing cargo.

It has a standard press release button (power on/off) for reading temps. The unit is intrinsically safe and can be used in hazardous areas.
