Sha-bab chilled water bath oscillator

1、 Overview

  Digital display freezing water bath constant temperature oscillator is widely used in medical, petrochemical, health and epidemic prevention, environmental monitoring, soil analysis and other scientific research departments in Colleges and universities for oscillation and constant temperature cultivation of various fluid and solid compounds such as biology, biochemistry, cells, bacteria, etc. This machine has the characteristics of reasonable structure, simple operation and high stability, which is an ideal equipment for the experimental personnel.

2、 Main technical parameters

The constant temperature range is 0 ～ 100 ℃± 0.5 ℃

Oscillation frequency starting ~ 300 times / min

Temperature fluctuation ± 0.1 ℃

Working mode: cyclotron plus reciprocating multi-function oscillation.

3、 How to use it

  First of all, please take off the stainless steel cover of the oscillator and add water into the water tank. According to the needs of the experiment, the amount of water should be controlled, but at least the water surface should be higher than the heating pipe to prevent the heating pipe from burning out. Generally, it is better to add 2 / 3 of the water tank. If too much water is added, the water will overflow and affect the experiment, Turn on the timer until it is normally closed "on" or you need to set the time, the indicator light is on, indicating that the power supply in the machine has been connected, and the oscillation frequency is controlled by the speed control knob, and it is adjusted from low speed to high speed from left to right. Set temperature: press set key to set or view the temperature set point. Press set key once, and the nixie tube character starts to flash, indicating that the instrument enters the setting state. Press the Δ key to increase the setting value, press the ▽ key to decrease the setting value. Long press the Δ key or ▽ key, and the data will change rapidly. Once again, the set key will return to the normal working state, and the temperature setting is completed. When the set temperature is lower than the ambient temperature, please turn on the refrigeration switch.

4、 Precautions

1. The instrument shell should be properly grounded to avoid accidents.

2. All kinds of liquids are forbidden to enter the machine, so as to avoid damaging the host.

When not in use, the power supply should be cut off, the water tank should be wiped dry and placed in a ventilated and dry place.
