When the thermometer is the IC thermo sensor (S8100) or diode (1S1588) is used as thermal sensors.When using the IC thermo sensor, the thermometry to +100 ° C -40 ° C are possible.
Also, when using the diode, measured at 150 ° C from -20 ° C are possible. Both sensors are contained in the set.
This time I used the diode as a heat sensor to measure more than 100 ° C. ICL 7136 of Intersil (Harris) used for the thermometer and measure the voltage change minute by management before the temperature diodes.
The 3-1/2 digit LCD (SP521PR) applied to the screen. The most significant digit can display a “1″.
ICL7136 electricity consumption is very small and it is possible to run about 3 months with 9-V cell.
The essential parts are contained in the set. The plastic casing and the cell is contained. But there is a cable connecting the sensor.
