61-1020/61-0230 Molecular Property Spectrometer
WARNING: When using the 61-1020/61-0230, you must follow the instructions and warnings
in this manual to assure proper and safe operation of the 61-1020/61-0230 and to
minimize the risk of personal injury. Be sure to maintain and periodically
calibrate the 61-1020/61-0230 as described in this manual.
Applications
The MPS combustible detector is most effective in the following applications:
• High concentrations of hydrogen sulfide (H
2
S) or silicones present where sensor
poisoning is a common problem
• High-humidity environments where catalytic or IR sensors may not hold up
• Environments more likely to have mixtures of hydrocarbons present
