High temperature and low temperature constant temperature bathWork environment:
1. The constant temperature bath should be placed on a sturdy workbench;
2. No vibration;
3. The room temperature should be relatively stable and not fluctuate rapidly, otherwise it will affect the temperature control accuracy; The room temperature should be around 25 ℃ (-40 ℃, -65 ℃, -80 ℃ constant temperature bath). Excessive room temperature can affect compressor heat dissipation, reduce refrigeration efficiency, and easily cause malfunctions;
4. The constant temperature bath should be regularly maintained. If the cooling rate slows down after working for a period of time, the plastic mesh plate of the constant temperature bath should be removed and the dust on the compressor and heat dissipation plate should be cleaned.

Description of optional temperature control function inside/outside the constant temperature bath

This sink has internal and external circulation functions (optional with external PT100 temperature sensor), which can conduct constant temperature experiments inside the sink and also establish a closed second temperature field externally. When used as a second temperature field, the internal and external temperature sensors behind the machine can be usedMeasure and control the temperature of the second temperature field.

High temperature and low temperature constant temperature bathUsage:

When conducting a constant temperature test in the sink, simply turn the temperature switch to the internal temperature.

When it is necessary to establish a second temperature field for use, connect the external temperature sensor equipped on this machine to the machine, first turn the temperature switch to the internal temperature, set the water tank temperature to the desired temperature, wait for the instrument to display a stable temperature for 10-20 minutes, then turn the temperature switch to the external temperature. At this time, the constant temperature bath can be controlled by a PID temperature control instrumentControl the temperature of the second temperature field.

Attention: Do not directly turn the temperature setting switch to the external temperature, in order to avoid accidents caused by the slow rise of the external temperature and the high temperature inside the constant temperature bath.
