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.
