Available Configurations

The Doric Instruments 400A Series Digital Indicator has a -1000 to +3500 and -10000 to +35000 count resolution, and a large, easy-to-read LED display. Signals from thermocouples, RTD, and thermistors can be displayed with 1°, 0.1°, or 0.01° resolution. High instrument accuracy is achieved with a superior combination of low noise analog-to-digital conversion, multi-segment linearization conformity, and isolated electronics stability. It can measure temperature in °C or °F without recalibration. Plug-in options make field enhancements and application changes easy. Installations can be made in minutes without special instructions or soldering equipment.
