The ST4 dual digital thermometer for K-type thermocouples.

The ST4 dual digital thermometer provides accurate measurements using any K-type thermocouple. It comes with two bead-type K-type thermocouples for measurement of temperatures in different locations at the same time. The unit can note the real-time difference between the two readings and display it. The unit can be used while still inside the carrying case. A supplied magnet allows it to be hung. The unit can be calibrated in the field. Once calibrated, it is accurate to plus/minus one degree between 0°F and 180°F.
