Moisture tracer - MM400

Analyzers of series MM400 have been designed to determin the moisture level in gases. The MM400 offers ease in use and an excellent cost/performance ratio. The MM400 works with a high quality aluminium oxide moisture sensor. It offers reliable  results from -100°C…+20°C dewpoint. The aluminium-oxide sensor is maintenance-free and is used in most demanding dpplications in industry and research.
The applied P2O5 principle is an absolute measuring method, which does not require any calibration.
  • Response time (humid to dry): <1min_ from -20°C…-60°C
  • Response time (dry to humid): <1min_ from -100°C… -20°C
  • Measurement inaccuracy: 1% of +20°C…-60°C, 2% of -60°C…-100°C
As standard the MM400 is available as bench mounted version, as field verson or as 19″ rack version. The casings can be modified with expansions or cutouts just to customer’s demand. For special applications the sensoric can be used as transmitter (MT27 Moisture Spy) without further electronics.
  • Bench-mounted version MM410: 190x137x410mm
  • Field version IP66 MM420: 460x380x160mm
  • 19″ rack version MM430: 178x484x410mm
 
The measurement area can be defined as moisture level or dewpoint.
  • Moisture content (volume): <0.1…>2000ppm
  • Dewpoint (Celsius: -100…20.0°C approx
  • Dewpoint (Fahrenheit): -148…68.0°F appox.
