FujiElectric ZKM zirconia gas analyzer

Introduction: FujiElectric ZKM zirconia gas analyzer

FujiElectric ZKM type

   peculiarity

   Zirconia sensors can be replaced and maintenance is simple.

   Fast response speed of 4~7 seconds, which can be used for combustion control.

   Two types of housings, IP66 and IP67, are available for different use environments.

   It has the function of aging diagnosis and regeneration of the sensor electrode, which prolongs the service life and improves the reliability.

   It is possible to easily set the case without opening it. (When using ZKM1 housing)

   Various diagnostics and protection functions are designed for safety-oriented considerations.
