Low temperature water bath

Low temperature water bathIt is a constant temperature equipment developed according to the requirements of JTGE20-2011 "Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering" to provide sample maintenance for testing the three major indicators of asphalt. The machine adopts a compressor refrigeration system with an internal circulation device and a highly intelligent temperature controller. It has the advantages of high temperature control accuracy, fast cooling speed, complete machine design, scratch resistance, generous appearance, and durability. This machine can also be used in fields such as petroleum, chemical, pharmaceutical, and biology, or for constant temperature experiments on test samples.

1Low temperature water bathtechnical indicators

1. Working power supply: AC 220V (-5%~10%), 50Hz.

4. Heating power: 1000W.

5. Refrigeration device: 500W

6. Temperature control range: 5 ℃ to 80 ℃.

7. Temperature control accuracy: ± 0.1 ℃.

8. Environmental temperature: ≤ 30 ℃.

9. Relative humidity: ≤ 85%.

10. Power consumption of the whole machine: not exceeding 2000W.

11. Dimensions: 560x540x950mm

12. Net weight of the instrument: 50kg

IIInstrument operation:
1. When the required temperature is higher than the ambient temperature, operate as follows:
A、 Turn on the power switch
B、 Set the desired temperature on the temperature control instrument.
Attention: When setting the temperature, do not press the SET button. When the instrument is in normal state, press the up or down button to enter the setting value modification state. At this time, the decimal point in the lower right corner of the digital display flashes. Press the up, down, and left buttons again to modify the setting value. After modification. Press the SET button to save and exit. If there is no button operation, it will automatically exit the set state after about 5 seconds and return to the normal measurement and control state.
C、 After setting the desired temperature, turn on the circulation switch and also turn on the cooling switch. At this time, the heating system will automatically run, while the cooling system will always run, relying on the heating system to compensate for the heat loss caused by the cooling system.
D、 This machine has a compression mechanism for long-term use.
E、 *If the instrument is not used, the liquid inside the instrument must be drained.
IIIPrecautions for Circulating Water Bath Instruments
1. When installing the device, please check if the connection is correct.
2. To ensure safety, please connect the ground wire.
3. If the device is not working properly, please contact the manufacturer or intermediary and do not disassemble or operate it without authorization.
4. The machine cannot be turned on without adding water. The water level must be 3 centimeters higher than the test piece before the experiment can be conducted
