2.1.3 ZO21R-L Probe Protector
This probe protector is required for the general-use detector when it is used for oxygen
concentration measurements in powdered coal boilers or in fluidized furnaces to prevent
abrasion due to dust particles when gas flow exceeds 10 m/s.
When using a ZR202S general-use integrated type detector in the horizontal position, be
sure to select a probe protector ZO21R-L-
ᮀᮀᮀ-ᮀ*B to support the probe.
