SHA-2 cryogenic water bath constant temperature oscillator

Freezing water bath constant temperature oscillator(with refrigeration) Purpose:

The low-temperature water bath constant temperature shaker, also known as the low-temperature constant temperature shaker, is mainly suitable for the oscillation cultivation of various liquid and solid compounds such as biology, biochemistry, cells, and bacterial strains in scientific research departments such as universities, petrochemicals, health and epidemic prevention, and environmental monitoring. This product has the characteristics of reasonable structure, easy operation, and high stability performance, making it an ideal equipment for laboratory workers to handle with ease.

Freezing water bath constant temperature oscillatorcharacteristic:

1. Temperature control range: 0-100 degrees (with cooling).

2. Temperature control method: using microcomputer temperature control, temperature control, no overheating or overshoot phenomenon.

3. There are three oscillation modes: rotary, reciprocating, and dual function. (Choose when placing an order)

4. Inner liner material: stainless steel, universal spring clamp, and different clamps can also be designed according to requirements.

5. Shell material: Static spray coating on the surface of the cold plate for rust prevention and extended service life.

6. Motor type: Permanent magnet DC motor, small size, high power, long service life, and also has the characteristics of low noise.

7. Speed regulation mode: stepless speed regulation, or microcomputer closed-loop control speed regulation mode (speed display, speed deviation of 0) can be selected.

8. Safety category: equipped with leakage protection, automatic power-off function, over temperature protection, and sound and light alarm.

9. Timing range: 0-120 minutes or microcomputer 0-9999 minutes with timing and normally open function.

Freezing water bath constant temperature oscillatorusage method:

Firstly, check if the water valve of the instrument is closed, add water to the appropriate height, and then plug the power plug of the instrument into a power source with a capacity of not less than 2 kilowatts and a "grounded" connection. Select the timer to the desired working time or to the normally open position. Press the power switch, and the power indicator light will turn on to indicate that the internal power supply has been connected. Rotate the speed control knob to select the desired oscillation frequency.

Temperature selection: Press the 'set' (function key) to select the desired temperature when the temperature controller displays' sp '. Adjust the up or down key to select the desired temperature. Once selected, press the' set 'key to exit. At this point, the upper digital display shows the actual temperature inside the slot, and the lower display shows the set temperature. Due to the use of a temperature controller, the instrument has an automatic switching function between heating and cooling, eliminating the hassle of previous operations.

Freezing water bath constant temperature oscillatorPrecautions for use:

1. The cooling process must be stopped and restarted with a 3-minute interval.

2. Before adding water to the water tank, heating work cannot be carried out, that is, the temperature should be set below room temperature. To prevent damage to the heating tube.

Low temperature water bath constant temperature oscillator (with refrigeration) maintenance:

1. When the power is turned on but the instrument does not operate, it may be due to fatigue elongation or aging fracture of the belt, which should be replaced.

2. If the instrument is not used for a long time, the water in the water tank should be drained, the water tank should be wiped clean, and placed in a dry and ventilated place.

3. Distilled water should be used for the experiment to avoid water contamination inside the box, which may affect the performance indicators of the instrument.
