Accurate, repeatable measurement of humidity is mandatory for processes that use vapor as a heat source to facilitate drying. The drying process can consume significant amounts of fuel in order to operate the dryers. Therefore, proper control can reduce operating expenses and optimize the process as well. The EXAxt ZR402 analyzer features the industry's latest technological advances such as, easy-to-read, simple-to-use, LCD touch screen operation; real-time trend graphing of process variables; two user configurable analog outputs; and, three user configurable measurement parameters. .

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. 

The ZR probe's in-situ measurement method does not require any process conditioning or extractive sampling. This reduces maintenance costs and allows faster measurement response to changes in the process. 

Yokogawa's Zirconia oxygen detector systems offer a variety of calibration units for quick, easy control of calibration gases giving the user simple, accurate calibration.
