2.2.2 ZO21R-L Probe Protector
This probe protector is required for the general-use detector when it is used for oxygen

abrasion due to dust particles when gas flow exceeds 10 m/s.
When using a ZR22S separate-type explosionproof detector in the horizontal position, be
sure to select a probe protector ZO21R-L-
ᮀᮀᮀ-ᮀ*B to support the probe.
