Home Gas Analyzer Indonesia Model 207 Portable Dew Point Analyzer (NOVA)
Model 207 Portable Dew Point Analyzer (NOVA)

A built-in sample pump draws in samples that are of insufficient pressure from the process. The sample flow is shown on a small rotameter with valve. The analyzer then reads the dew point continuously.


For checking dew points of air, heat treat furnace gases, compressed air lines, and other applications with oils or contaminants present.

• Standard range of -40°F to 104°F (or -40°C to 40°C)
• Rugged design that is easy to operate
• Use on any non-corrosive gas
• Long-life dielectric polymer sensor
• May be calibrated in the field
• Bright digital readout
• Built-in sample pump, filter, and flow meter
• Suitcase style enclosure is standard

Equipment has always been an important part, having equipment that is technologically advanced gas analyzer can make the job easier. In terms of precision gas analysis, and the accuracy of the data becomes very important, therefore we as a supplier of gas analyzer Indonesia equipment very understanding so we always give priority to products that have the precision and accuracy of the data from the gas analyzer.
