The DM650HM humidity gauge has been designed to display % relative humidity, temperature, dew point and delta temperature, on a 6- digit LCD display. 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.
The DM650LP loop powered process switch and indicator, accepts a (4 to 20) mA signal and displays the process value in the appropriate engineering units on a 6-digit LCD display. The instrument offers an advanced display mode allowing the user to also display one or two (1 to 32) character messages.Additional to the messages, the user may select an alert event to occur when the temperature is within a band. The change-over relay can be used together with the messaging and alert to provide switching at user set switch points. This means the instruments can be used as a loop powered process switch depending on which type of process the (4 to 20) mA loop is measuring. For example temperature or pressure
The DM650PM battery powered digital pressure gauge accepts gauge or absolute pressure and displays the gauge or absolute sensor pressure in BAR, PSI or the user’s engineering unit on a 6-digit LCD display. The instrument offers an advanced display mode allowing the user to also display one or two (1 to 32) character messages. Additional to the messages, the user may select an alert event to occur when the pressure is within a band. A change-over relay can be used together with the messaging and alerts to provide switching at user set points. In addition to this, on board data-logging is also available to record process details at up to 5000 points.
The DM650TM digital temperature gauge accepts RTD or thermocouple temperature sensors and displays the sensor temperature in °C or °F on a 6-digit LCD display. The instrument offers an advanced display mode allowing the user to also display one or two (1 to 32) character messages. Additional to the messages, the user may select an alert-event to occur when the temperature is within a band. The change-over relay can be used together with the messaging and alert to provide switching at user-set switch points. In addition to this, on board datalogging is also available to record process details at up to 5000 points.
TheThe DM650XTM, UKEX, ATEX and IECEx approved temperature gauge for RTD or thermocouple temperature sensors, displays the sensor temperature in °C, °F or K on a 6-digit LCD display. Configuration is achieved by operating a single push button and navigating a menu structure. A contact-less NFC interface is also provided for configuration and the data logger function UKEX, ATEX and IECEx approved temperature gauge for RTD or thermocouple temperature sensors product features: The instrument is powered by two AAA 1.5 V batteries. The battery life is dependent on the number of active features such as configuration response time and logging. Battery life is up to 5-years plus (1-year minimum depending on options selected)
The DM650VI is a battery powered process gauge. The instrument accepts a signal within the ranges of ±50 V or ±50 mA signal and displays the process value in the appropriate engineering units on a 6-digit LCD display. The instrument offers an advanced display mode allowing the user to also display one or two (1 to 32) character messages. Additional to the messages, the user may select an alert event to occur when the temperature is within a band. The change-over relay can be used together with the messaging and alert to provide switching at user set switch points. In addition to this, an on board data-log function is also available to record process details at up to 5000 points.
The DM665TM large digit temperature gauge accepts  Th instrument is powered by two AA batteries. The product is supplied with 1.5 V AA
alkaline batteries. This will give the DM650TM a minimum battery lifetime of over one year.
Used with Lithium Energizer L91batteries (not supplied), the battery lifetime can be
extended to over 5 years. Battery lifetime is dependent on the ambient operating
temperature range and the sample rate selected.
The DM670TM large digit temperature gauge accepts RTD or Thermocouple temperature sensors and display the
sensor temperature in °C or °F on a 6-digit LCD display. The instrument offers an advanced display mode allowing
the user to also display one or two (1 to 32) character messages. Additional to the messages, the user may select
an alert-event to occur when the temperature is within a band. The two changeover relays can be used together
with the messaging and alert to provide switching at userset switch points. In addition to this, on-board datalogging
is also available to record process details up to 5000 points.
The DM670PM series of battery powered indicators accept gauge or absolute pressure and displays the sensor pressure in BAR, PSI or the user’s engineering unit on a 6- digit LCD display. The instrument offers an advanced display mode allowing the user to also display one or two (1 to 32) character messages. Additional to the messages, the user may select an alert-event to occur when the pressure is within a band. The two change-over relays can be used together with the messaging and alerts to provide switching at user-set points. In addition to this, on-board datalogging is also available to record process details at up to 3600 points.

Small and compact, the ATEX approved DM700X loop powered indicator has been designed to be completely enclosed in a clear polycarbonate cap which fits to our standard SCH4 enclosure.

The unit is microprocessor based and the displayed process range is achieved by means of three push button switches located on the underside of the module following a simple menu structure.
