Operation 

H25-IR 

 

32

 

Instruction 3015-4342 

After finding a leak, a measurement can be made to determine its leak rate as follows: 
 

1.  Press the MODE button to display “MERS” at the bottom of the Data Display screen or “MEASR” 

on the Smart probe. 

 

2.  Allow the instrument to sample fresh air. The gas reading must be “0.00” before proceeding. If 

necessary, press the ZERO button to zero the reading while sampling fresh air. 

 

3.  While observing the gas reading, hold the probe tip over the leak source until the reading 

stabilizes. In the examples below, a leak rate of 2.80 Oz/yr of R134a is being measured. 

 

 
 

 

 
 

 

 

The H25-IR can be used to measure a gas’s ppm level within a confined space, and display that level 

within the range of 0 to 1,000 ppm. Set up the instrument to measure ppm levels as follows: 
 
NOTE: 

 

1.  Set up the instrument’s Leak Units to ppm as described in Section 2.4.2 Leak Units. 

 

2.  Press the MODE button to display “MERS” at the bottom of the Data Display screen or “MEASR” 

on the Smart probe. 

 

3.  Allow the instrument to sample fresh air. The gas reading must be “00.0” before proceeding. Press 

the ZERO button to zero the gas reading while sampling fresh air. 

 

4.  Place probe in area to be measured. In the example below, 38.0 ppm of R134a is being measured. 

Note that the display is auto ranging, causing the decimal point to turn off above 99.9 ppm.
