Operation steps of low temperature constant temperature water tank

The selection of liquid medium should pay attention to:
(1) When the working temperature is lower than 5 ℃, the liquid medium generally uses alcohol.
(2) When the working temperature is 5-80 ℃, the liquid medium generally uses pure water.

(3) When the working temperature is 80-90 ℃, the liquid medium generally uses 15% glycerin aqueous solution.
(4) When the working temperature is 90-100 ℃, the liquid medium is generally oil.
2. Connection of the circulation pump A: connection of the internal circulation pump, connecting the outlet pipe to the inlet pipe with a hose, or a hose can be randomly provided B: external circulation pump is used for external circulation connection, and the outlet pipe is connected with a hose At the inlet of the container outside the tank, connect the inlet pipe to the outlet of the container outside the tank. Note: The pipe on the left side of the instrument is the inlet pipe, and the pipe on the back is the outlet pipe.
3. Plug in the power, turn on the "power" switch, and turn on the "cycle" switch.
4. Instrument operation A: Shift, ▲ Add, ▼ Decrement, 〖SET〗 to set function keys.
B: Temperature setting: Press the setting function key to enter the temperature setting state, the last bit of the setting value flashes, at this time, first press the shift and then press plus or minus to set the working temperature you need, then press the set function key And save the set value. At this time, the measurement shows the temperature of the liquid medium in the current tank, and then the microcomputer enters the automatic control state. The set working temperature should be higher than the indoor temperature + 8 ℃
C: If the working temperature of the low-temperature constant-temperature water tank is lower than the ambient temperature, turn on the "cooling" switch to cool to the desired temperature.
