The DPI 822 is a compact and easy to use instrument for testing, configuring and calibrating Thermocouples (including Type K). The instrument is 35% smaller than competing models. The windows-like menu-driven display offers simple operation of the instrument with few buttons, making it simple and easy to understand. The DPI 822 can be extended with a datalog option, so you don't have to carry extra datalog instruments in the field.
So-called IDOS pressure sensors can also be connected. The connected pressure sensor is automatically recognized by the DPI 822. For the specifications of the IDOS sensors, please refer to the separate web page on our site: http://eurotronbenelux.nl/product/idos-sensoren.
The instrument is accurate and with a single push of a button you set it to the value to be measured or simulated. The DPI 822 measures and simulates all Thermocouple signals. To calibrate transmitters, you can measure mA signals and supply the instrument with 24 V supply voltage under test. The built-in 250 Ohms resistor can be switched on if you want to calibrate Hart transmitters.
