DM640 Series Battery Powered Thermometer from Status Instruments, Inc.

The Model DM640 Cap Series is a line of battery powered temperature indicators which accept an RTD or thermocouple input depending on the model. The face of the Cap houses a 4 digit LCD display. The back contains the screw terminal connections, battery, and three push buttons used to program and calibrate the unit.

The sensor type is selected from a simple to use menu system which is navigated by the use of the three push-button keys. The menu also allows the user to select units (°C or °F ), offset temperature, decimal point position, and password protection.

The entire assembly is sealed into a Cap that fits directly into the SCH series of NEMA 4X and Explosion Proof housings. Optional mounting kits are available for placement of the Cap into other style housings if needed.
