INTRODUCTION
This thermometer is an advanced electronic tool. It has the advantages of
low battery consumption, hight stability and easy use. It has a long stainless
probe so that you can use it to measure the temperature of an object which
other thermometers are not suitable to measure. For example you can use it to
measure oil temperature in engine but also the diet under cooking, the cereal
in storage, the wine, the water, room temperature…
It can automatically record the maximum and minimum temperature readings.
