Thermo Electron Model 41H CO2 gas filter correlation analyzer. Complete working unit. This model has all the same basic parts as model 48 CO, even the detector, except some parts and program solfware. Most parts are interchangeable with model 48, 41, 45, ...
There are 10 ranges from 5ppm to 5000ppm CO2
Read ambient CO2 as seen in picture. A Model 48 manual (not 41H) is available for copy. For other analyzers see my current listings.
(Also if you need PMT tubes and sockets for TECO 42, 42s, 42c, 42d, 42H, please contact me)
