DM640 Battery Powered Thermometer

Brand: Status Instruments

The DM600 series of battery powered indicators accepts either an RTD (DM640P) or a Thermocouple (DM640TC) input.

Each device shows the temperature on a 4 digit LCD display. The unit is microprocessor based.

The sensor type is selected from a simple to use menu system which is navigated by the use of three push buttons located on the rear of the display. This feature enables the user to easily configure the device in the field without the use of any other equipment.

The DM640P and DM640TC are sealed into a cap as pictured above. There are several mounting options including the SCH4 series of enclosures and a stainless steel option, the SCH15 ATEX versions are available for use in hazardous dust and gas areas.
