Characteristics and operation precautions of digital display low temperature thermostatic bath

Issue date:2022/03/08    Views：83    Classification：Company news

Features of digital display low temperature thermostatic bath:

A. refrigeration of fully enclosed compressor unit;

B upper and lower limit temperature alarm can be set;

C inlet temperature control program, stable operation;

D has multiple protection devices for overheating and overcurrent;

E has power-off protection function, which can automatically delay for 3 minutes;

F adopts XMT analog digital PID automatic control system and LCD display;

G circulating pump can lead the thermostatic liquid out of the tank to establish a second thermostatic field;

The cold liquid in H tank can be introduced outside, and the test container outside the cooler can also be used for low temperature test directly in the tank.

The inner and upper outer grooves of the digital display low-temperature thermostat are made of high-quality stainless steel, the shell is made of simple cast steel, and the bottom is made of pulley structure (equipped with a pedal to control the rotation of the pulley). The whole machine has a beautiful and simple appearance. The thermostatic bath introduces a new generation of temperature control program from the United States in the temperature control area. Combined with its own experience and technology in producing thermostatic water bath pots for many years, the temperature control accuracy can be accurate to 0.05 ° C in the temperature control area. For the medium is oil with high consistency, the accuracy can also be accurate to 0.1 ° C. It is equipped with internal and external circulation in the low-temperature constant temperature bath. Internal circulation: cyclic huff and puff of liquid medium in the tank through the pump to increase the uniformity of temperature in the tank and reduce temperature fluctuations. External circulation: through the circulation capacity of the pump, the water outlet is used to connect the insulation hose with the external equipment to form a closed loop, which flows back to the water inlet of the equipment. It is to introduce the constant temperature medium in the tank and establish an external constant temperature field.

Precautions for using digital display low temperature incubation bath:

1 keep 40mm around the instrument without obstacles;

2. The power supply power should be greater than the power used by the instrument;

3. The instrument has pump circulation, and it is recommended to turn on external circulation;

4. For the use of media, please refer to the instructions;

5 clean up in time and keep the instrument clean;

Selection principle of liquid medium in digital display low temperature constant temperature bath:

When the working temperature is 5-85 ° C, the liquid medium is generally water;

When the working temperature is 85-95 ° C, the liquid medium can be 15% glycerol aqueous solution;

When the working temperature is 95 ° C, the liquid medium is generally oil, and the open cup flash point of the selected oil should be more than 50 ° C higher than the working temperature;

There is a pulley at the bottom of the instrument, which can be opened during the movement to facilitate the movement. When the instrument is running, please fix the pulley to avoid damage caused by the movement of the instrument during operation. The instrument has high power. Before use, ensure that the power supply power is greater than the use power of the instrument to avoid short circuit of the instrument. Percival low temperature constant temperature bath adopts three foot plug and has bottom line device.

When adding medium into the low-temperature constant temperature bath, it should be ensured that the water level of the instrument is exceeded, so as to avoid the dry burning of the instrument heater. Percival low temperature constant temperature bath has the function of low water level alarm. When adding media, you can hear the beep. If there is a beep when the instrument is running, it means that the instrument is in a low water level state, you should add sufficient media in time. Ensure the safe operation of the instrument. When using the digital display low-temperature thermostat at high temperature, do not look too close to the opening directly. If the medium used is oil, it may splash.

For the instrument with external circulation function, it is recommended to turn on the pump circulation when it is used at low temperature to prevent the freezing phenomenon due to low water temperature from affecting the experiment. The pump circulation is conducive to more constant water temperature, so it is recommended to turn on.

When the instrument is used, turn off the instrument switch first, and then disconnect the connecting line. Clean the instrument in time to avoid dirt affecting the next experiment. The instrument should be placed in a ventilated place to avoid humidity.
