MDM300

 Advanced Dew-point Hygrometer
The MDM300 includes all the features needed for efficient work. An extremely fast response and accurate, stable measurement is complemented by an instrument which is easy to use, has data-logging and built in sampling components as standard, and can be supplied with a range of accessories including a stand-alone sampling system and a professional carry case. It is IP66/NEMA 4 rated, and so is suitable for demanding outdoor applications.





Product Features

  • Repeatedly fast measurements in less than 10 minutes for T95 down to -70°C dp
  • Long battery life: more than 48 hours of typical usage between charges
  • Best in its class: 1°C dp accuracy
  • External 4-20mA device input for dew-point, temperature or pressure transmitters
  • Bluetooth connection for less trouble with missing cables
  • Versatile sampling systems enable measurements of up to 400 bar
  • Easy operation - just switch on and measure
