1. Agency approved hydrogen sensors are MPD-CB1 and 705 STD.
2.
When ordering replacement MPD sensor cartridges, the replacement cartridge must be the same type as factory configured. Substituting a different cartridge
will void agency certification.
3. On XNX %LEL units carrying UL/CSA certifications, the range is fixed at 100%LEL and is not adjustable.
4. Humidity: 5% to 95% RH non-condensing
5. Humidity: 0 to 99% RH non-condensing
