TEMPERATURE CONTROLLER PT-421

PT-421 is a device used for air or water temperature continuous measurements. Enables the temperature regulation with use of relays (maximum and minimum).

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.
PT-421 is equipped with a hanger for mounting on a wall.
24 months of warranty.

The meter enables storing of 8000 results. The built-in memory allows you to remember the results with a set time interval: the shortest 1 minute, and the next possibilities: 2, 5, 10, 15, 30, 60 minutes. When the memory is full, the oldest result is deleted and a new one is added. The results can be transferred to a computer via USB. The delivered in the set computer software allows to transfer the results of the measured function and temperature with the date and time of recording.
