DM650HM

Battery powered humidity & temperature gauge with data logging, alarm & display messaging

The DM650HM humidity and temperature display has been designed to display % relative humidity, temperature, dew point and delta temperature, on a 6- digit LCD display.

Battery powered, the instrument offers an advanced display-mode, allowing the user to display not only process variables but one or two (1 – 32) character messages. This feature is further enhanced by the ability to split a process range into eight user-set bands, each band having independent user selected messages.

The DM650HM also has a changeover-type relay with multiple programmable options allowing the user to set a high, low or deviation alarm.  Wall and duct-mounted versions are available.

Funktionshöjdpunkter

RELÄ
The instrument is equipped with single volt-free change-over type relay. The user may select one of
several actions, including deviation operation, with fully adjustable set-point and dead-band. An option is
provided to trigger an alert-event when a relay contact is on. The relay can be used to alarm on any of the values of relative humidity, temperature, dewpoint or delta temperature. A battery-monitoring function is also provided.

DATA LOGGING FUNCTION
DM650HM humidity gauge also provides a powerful data logging-function. The log points can be set up to 5000 points, each
point is time and date stamped together with %RH, temperature and relay-state information.
The log rate is selectable in steps. The start of log can be delayed if required. Either fixed or rolling logs
kan utföras.
Two methods of reading the log are available. The USB configuration reads the log and allows the user to
save to a text file. The NFC android interface allows data transfer to compatible android phones or
tablets; by using the downloadable App, the data can be graphed and forwarded by email, Bluetooth etc.
The NFC interface is also capable of starting a new log with different log periods and modes.

FLEXIBLE DISPLAY OPTIONS
The DM650HM can display any combination of the following process variables: % relative humidity,
temperature, dew point and delta temperature.

REAL-TIME CLOCK
Date and time can also be displayed with the input values. The real-time clock is used to record the data
logged points.
