TEMPERATURE CONTROLLER PT-421


PT-421 is a device used for air or water temperature continuous measurements.


The controller cooperates with a PT-1000s platinum temperature probe of higher accuracy, build in a steel pipe of 3 mm diameter.
It is possible to calibrate the meter by entering the probe's data.
Cable and probe length may be determined by the customer (standard: 5 m).
The meter is equipped with a large, easy-to-read backlit LCD display.
Recomended types of cables: silicone, resistant to temperature up to 250°C, with additional protection (steel braid) 250 °C.
