Heating and cooling thermostatIt is a high-precision constant temperature source with built-in cooling and heating, which can be used for constant temperature experiments in the machine's water tank or connected to other equipment through a hose as a matching constant temperature source. Heating and cooling thermostats are widely used in research departments such as petroleum, chemical, electronic instruments, physics, chemistry, biotechnology, medicine and health, life sciences, light industry and food, physical property testing and chemical analysis, as well as in higher education institutions, enterprise quality inspection and production departments. They provide users with a controlled and uniform temperature field source for constant temperature testing of test samples or products, and can also be used as a direct heating or cooling source and an auxiliary heating or cooling source.

The heating and cooling thermostat is a constant temperature metal bath product manufactured using microcomputer control and semiconductor cooling technology. The heating and cooling thermostat can be configured with multiple modules and can be widely used for sample preservation, enzyme preservation and reaction, nucleic acid and protein denaturation treatment, PCR reaction, electrophoresis pre denaturation, and serum coagulation. The following is the operation method for its use:

Temperature setting of heating and cooling thermostat:

(1) Turn on the power switch, and all indicator lights and digital tubes of the heating and cooling thermostat will light up. After about 5 seconds, the number displayed on the real-time temperature display window (PV) is the real-time temperature of the metal module, and the number displayed on the set temperature display window (SV) is the set temperature from the last use.

(2) Press the (Set/SET) button once, and the number on the left side of the temperature display window (SV) will flash. Use the up and down keys to change the flashing number to the desired value.

(3) Press the (Set/SET) key again, the flashing number shifts one digit to the right, and use the up and down keys to change itHeating and cooling thermostatBlink the numbers until the desired value is reached.

(4) Press the (Set/SET) key again, move the flashing number to the right by one digit, and use the up and down keys to change the flashing number until the desired value is reached, completing the temperature setting process. Or press the (Set/SET) key again and start setting again from the left.

(5) After 8 seconds of completing the temperature setting, the digital flashing phenomenon disappears, indicating that the local system has entered the running state and is operating according to the current set temperature value.

Precautions for using heating and cooling thermostats

1. When either the automatic sampler or the heating and cooling thermostat is powered on, the cable between these two components must not be disconnected or reconnected. This will damage the circuit of the module.

2. Unplug the power cord from the automatic sampler and the heating and cooling thermostat to disconnect the automatic sampler from the circuit power supply. But even if the power switch on the front panel of the automatic sampler is turned off, the automatic sampler is still live. Please make sure to unplug the power plug at any time.

3. If the device is connected to a voltage exceeding the specified line voltage, it may pose a risk of electric shock or damage to the instrument.

4. Ensure that the condensate pipe is always above the liquid level of the container. If the condensate pipe extends into the liquid, the condensate cannot flow out of the pipe and clogs the outlet. This will damage itHeating and cooling thermostatThe circuit.
