The impact test low temperature meter series developed by Liangong has a temperature control accuracy of ±0.5°C; a wide range of refrigeration, from room temperature to -196°C, any temperature can be controlled. For any high-precision equipment, be sure to familiarize yourself with the precautions of the equipment and perform routine maintenance work during use.
Impact test low temperature meter (low temperature tank) routine maintenance and precautions:
1. Keep the equipment clean, strictly prohibit vibration and collision, and do not disassemble it at will.
2. The equipment should not be placed near high temperature or exposed to sunlight.
3, The electric control box should pay attention to moisture, it is strictly prohibited to enter any liquid.
4. The sample placed in the cooling tank should be dry and clean. Do not bring foreign matter such as iron filings into the cooling tank. The notch of the sample faces the left, that is, the side of the injection cylinder, which is convenient for holding the impact.
5. Wear dry protective gloves when installing samples at low temperature to avoid frostbite.
6. When using, the temperature is gradually lowered from high temperature to low temperature. If the temperature is low, 50 °C should be used for a section of constant temperature for 5 minutes to gradually cool down. When used from low temperature to high temperature, the solenoid valve may be out of control, and it is necessary to return to normal temperature and then cool down again.
7. If it is a low temperature tank for liquid nitrogen refrigeration, the liquid nitrogen tank must not be moved during the test to avoid liquid nitrogen overflowing frostbite.
8. When the equipment fails, please contact our company in time.
