Introduction to products
The instrument is driven by a 9v battery, the temperature shown by a digital liquid crystal thermometer, which can be used as a temperature sensor by any k-type thermoelectric doll, which can measure the temperature of both degrees centigrade and fahrenheit and can also measure temperature differentials (two-channel temperature tables). There are multiple functions such as data maintenance, low voltage displays, tight design, accurate measurements, easy to use。
Ii. Product parameters
Single channel temperature table between -50°c and 200°c with resolution of -50°c
0. 1°c, double-channel temperature tables can measure t1 and t2 respectively, or
The temperature margin of t1-t2 is measured. It's all cm, fahrenheit conversion。
