INTRODUCTION
The MDM300 Advanced Dew-Point Hygrometer is a portable instrument designed for on-line
measurement of moisture content in non-corrosive gases over an operational range of
-100 to +20 °C (-148...+68 °F).
The instrument is contained within a steel fiber-loaded high-impact polyamide 6 case,
sealed to IP66 / NEMA4 standard and is powered by an internally mounted Nickel
Metal Hydride (NiMH) battery, designed to typically provide 48 hours continuous use
between charges. Continuous battery charge status indication is provided. Additional
battery status information is provided by a battery indicator icon, in addition to a warning
beep and Shutdown Mode.
The MDM300 is fitted with an internally mounted ceramic sensor, which is enhanced for
a quicker response to dew points as dry as -75
°
Cdp (-103
°
Fdp).
A 4...20 mA current loop input is provided, which can be programmed to interface with
a number of different external transmitter inputs.
•
Pressure range 0...350 barg (0...5076 psig)
•
Temperature range -100...+100 °C (-148...+212 °F)
•
Dew-point (Easidew transmitter) range -100...+20 °C (-148...+68 °F)
A graphical display presents the dew-point data in large format characters and
simultaneously provides a primary display of real time dew-point readings and a
secondary display, in smaller characters, for the external sensor input. If no external
input is programmed, gas temperature (measured by the internal sensor) is displayed
by default.
A fully programmable, real-time, datalogging facility is provided which has an internal
memory capacity of 8Mb, capable of storing up to 10,000 logs per file (typically giving
a maximum of 64 log files).
A Bluetooth, wireless, communication system is provided, giving access to a dedicated,
PC based, MDM300 Software Application Package which provides the facility for handling
the logged data files and uploading and downloading instrument parameters.
A user-friendly operator interface provides easy access to all levels of the instrument’s
functionality.
An easy-to-follow calibration routine is built into the instrument’s software.
