CAUTION

Hansen Gas Detection Sensors, Monitors and Alert 
Systems have been designed for industrial and 
commercial refrigeration systems. These instructions 
must be completely read and understood before 
selecting, using or servicing Hansen gas detection 
equipment. Only knowledgeable, trained refrigeration 
personnel should install, operate, or service this gas 
detection equipment. Stated temperature and voltage 
limits should not be exceeded. See Safety Precautions 
in current List Price Bulletin and Safety Precautions 
Sheet supplied with product.

REVISION IDENTIFICATION LABEL "3E 100 1.0"

CIRCUIT BOARD

SPECIAL ELEMENT REPLACEMENT KITS 
(250 PPM GAS SENSOR ONLY)

FIG. 23

Gas Sensors (250 PPM only) shipped prior to April 2013 
may have older style circuit boards that will not match 

the new replacement sensing element. The proper circuit 
board can be identified by the electronics revision 
identification label of “3E100 1.0” or later, located 
inside the enclosure. If this revision identification label 
is present, use kit number 31-1024 for the 250 PPM 
Standard Gas Sensor, and 31-1025 for the 250 PPM 
Harsh/Extreme Gas Sensor. Otherwise, use special 
kit that includes replacement sensor and electronics: 
number 31-1026 for the 250 PPM Standard Gas Sensor, 
and 31-1027 for the 250 PPM Harsh/Extreme Gas Sensor.
