Davidson Measurement has released the DPI 800 series of calibrators. Nine models cover pressure and temperature, dual function versions also provide additional facilities for measuring mA, supplying 24 V power, testing switches and providing Hart compatibility.

Pressure models DPI800/802 use intelligent digital output sensors to provide 0.05% FS accuracy from 0 to 50°C, including one year stability (0.01% FS precision optional) and a choice of 22 pressure ranges is available from 25 mbar to 200 bar.

The DPI811/812 temperature variants provide RTD measure/source capability with 2, 3, 4 wire auto detection for identification of sensor and wiring faults.

The DPI820, a dual input data logging thermometer and the DPI 821/822 thermocouple calibrators use cold junction compensation to keep errors within 0.2°C, even for a 30°C rapid change in ambient temperature.

IDOS plug-in modules expand the range of any IDOS-compatible instrument and can convert a temperature calibrator into a fully featured pressure indicator.
