LEAK TESTING 

 

Unless specified otherwise by your license or state regulations

, the 

gauge must be leak tested at intervals not exceeding 12 months to 
ensure the integrity of the radioactive source encapsulation. Sample 
analysis must be performed by a licensed laboratory only. 

 

Using the Troxler Model 3880 Leak Test Kit (PN 102868) and 
accompanying instructions, perform the following procedure: 

 

 

Write the date, gauge model number, and serial number on the 
sample form and label. 

 

 

Remove the control panel from the gauge topshell. Locate the 
yellow radiation label on the top surface of the base. 

 

 

Holding the wipe disk with the tongs, wipe the radiation label. 

 

 

Turn the gauge on its side and locate the opening where the 
source rod extends through the gauge base. 

 

 

Holding the wipe disk with tongs, wipe the area around and 
inside the opening where the source rod extends from the gauge 
base. 

 

 

Pack the disk, as instructed, in the envelope and mail to Troxler 
Electronic Laboratories, Inc. for analysis. 

 

 

Secure the gauge properly. 

WARNING 

Ensure that the source rod is in the SAFE position 
(see 

Figure 3–3 

on page 3–5).
