Microprocessor Module Replacement Kit 

for H25-IR Infrared Gas Leak Detectors 

 

Instruction Manual 

 

 

 

 

1.  Scope 

The Bacharach H25-IR family of gas leak detectors is designed for easy maintenance and enhancement.  One element of 

that design is the ability to replace system programming (firmware) with a simple plug-in microprocessor module, 

minimizing downtime. 

 

This instruction manual describes how to replace or upgrade the microprocessor module in your H25-IR infrared gas leak 

detector.  It is assumed that the user is familiar with the operation of the device.  If necessary, refer to the instructions for 

detailed operation and maintenance information for each H25-IR model. 

 

2.  Items Required 

  Replacement Microprocessor Module Kit (P/N: 3015-5578) 

  Medium Phillips head screwdriver 

  H25-IR instruction manual (optional)
