Introduction
GRL-12 analyzer uses advanced humidity sensor made of solid electrolyte with good stability and special construction. It can measure the vapor pressure under 0-500ºC range. It has such characteristics of high precision, fast response, high performance, good stability, novel design, and full functions.

Features
Using in burning condition
Fast response, beyond the function of common humidity tester
Sensor is made of solid electrolyte and can work under high temperature environment.
Connecting to a printer via the standard (4-20)mA, RS232 and RS485 interfaces.
