Low temperature detection tank HC2010
1.1 technical parameters
Temperature range: - 20-95 ℃
Temperature fluctuation degree, plus or minus 0.05 ℃
Refrigerant: R12
Studio size: 180X100X200mm
Opening size: 180X100mm
Installation power: 0.8kw
2. Working conditions
Power supply: 220 + + 22V, 50Hz
Medium used in the tank: non-corrosive liquid
Ambient temperature: 5-23 ℃
Ambient humidity: less than 85%
The use of ambient ventilation is good, without strong column vibration, dust - free Egyptian corrosive gas
3. Control system
The refrigeration compressor is normally open during the low temperature test, and the digital control temperature meter is used to control the heating to achieve thermal equilibrium
The platinum resistance RT detects the actual temperature and passes it to the digital display control thermometer.At the same time, the digital display temperature control device automatically drives the controlled heating power of the thyristor after the actual temperature and the setting temperature, so that the temperature in the slot is stable in the set value.
When the above room temperature + 5 ℃ above, please do not open the compressor.

2. There is no inflammable and explosive material around, no strong vibration, no strong electromagnetic field, no high concentration of dust and corrosive substances, no direct sunlight or other direct radiation.
3. The equipment should be placed horizontally in a well-ventilated laboratory, with adequate space for operation and maintenance.
4. Power supply for single-phase three-wire power supply of 220 + + 22V, 50-plus or minus 1Hz.
5. Structural features
5.1.1 the equipment is divided into two parts, the structure is compact, the upper left side is the work area, the right side is the electrical control part, the lower box is the refrigeration system.
5.1.2 the electric control cabinet is mainly composed of temperature computer control instrument, ac contactor, insurance, solid state relays and other low-voltage devices.
6. Working principle
Controller according to the measured temperature control heating power, the temperature sensor and controller set point to compare, compare the results after a series of operations, adjust the on-off time of heating solid state relay, to adjust the heating power, make to the desired work indoor temperature constant values.
7. Operation and operation
7.1 use
7.1.1 only operators are allowed to use the equipment.
7.1.2 only the experimental material allowed by the equipment can be put into the box for testing.
7.1.3 the sectional area of the specimen shall not exceed 1/3 of the area of the studio in this section.
7.1.4 failure to collide the box door and box body when placing the specimen.
7.1.5 the weight of the specimen shall not exceed the weight of the base plate.
8. Quality assurance
In using comply with the product installation and after-sales service, the user rules and conditions, the product is 12 months from the date of the consignment is not work properly due to poor quality, we free repair for the user, and the warranty of products to provide long-term technical services.
