Gastec GV-100S and GV-110S Sampling Pump Manual

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The  Gastec  precision  pump  (GV-100S)  and  Gastec  Precision  Pump  with  a  counter  (GV-100S) is 
designed specifically to be used with Gastec standard and polytec tubes. Using this range you can 
monitor up to 600 gases and vapours.  
 
The  Gastec  precision  pump  and  Gastec  Precision  Pump  with  a  counter  can  precisely  collect  a 
sample volume for a detector tube. The full-stroke (100ml) and the half stroke (50ml) positions are 
marked  exactly  by  the  red  line  on  the  pump  shaft,  and  the  handle  is  precisely  locked  at  those 
positions. If you pump fully n times by allowing for sampling time intervals, a volume of 100ml x n 
can  be  sampled.  Each  detector  tube  is  calibrated  based  upon  a  prescribed  (standard)  volume  of 
sample. Also the pump piston has been designated with a smaller diameter so the handle can be 
pulled out with even less effort. The Gastec precision pump design proves you with advanced and 
non sparking design and superior features.
