2.1.3 ZO21R 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/sec.
When probe length of the ZR202G is 2.5 m or more and mounted horizontally, be sure to select a
probe protector ZO21R-L-200-*B to support the probe.
