Description
The ADT681IS-10-GP36K-PSI-AM-DL is configured for gauge pressure, range 0 to 36,000 psi, with 0.1% FS accuracy and an Autoclave high-pressure, male port, suited to high-pressure hydraulic testing. The DL option adds internal recording of pressure and temperature readings. The Additel ADT681IS is the intrinsically safe version of the ADT681 digital pressure gauge, intended for pressure measurement in hazardous locations. It uses the same temperature-compensated silicon sensor and display as the standard model, in an IP67-rated housing that is dust tight and submersible to 1 meter. Instrument technicians in oil and gas, chemical and pipeline facilities use it for transmitter checks, test readings and pressure verification where non-certified tools are not permitted.
