Emerson · Model TREXLHPKLWS3S · Process Instruments

Rugged, intrinsically safe handheld for commissioning, configuring and troubleshooting HART field devices directly in the field. This Plus configuration adds a second lead set and a built-in load resistor with HART power terminals so technicians can power the loop and configure transmitters before infrastructure is in place — and sync every time-stamped change back to AMS Device Manager.
