Бір арналы оттегі концентрациясын анализатор жүйесі ZR22/ZR402

ZR402G split type converter is equipped with LCD touch screen, easy to operate.
The probe’s built-in heater assembly is field replaceable, reducing maintenance costs (ZR22G only).
The probe uses a long-life, high-reliability, and online-replaceable zirconia sensor.
Remote maintenance using digital communication (HART) reduces maintenance costs.
