Integral Oxygen Analyzer ZR202

The EXAxt ZR202 transmitter / detector combines benefits of the ZR402 remote analyzer and the ZR22 detector into an intelligent, rebuildable, low-cost measurement device for in-situ humidity measurement. This smart probe features a local LCD display and infrared push-button operation for local adjustment of the instrument and calibration control. HART communication protocol allows easy configuration of the instrument as well as up to the second information on all process variables and diagnostic tools. The Yokogawa ZR202 smart probe offers customers a lower cost of product ownership by significantly reducing installation costs from tubing, wiring and conduit.
