Drop height (mm): 400-1500 Maximum weight of test piece (KG): about 60 Maximum size of test piece (mm): 1000*800*1000 Impact panel size (mm): 1400*1200*20mm Horsepower: increase 1/3P, manual width adjustment Overall dimensions of the test bench (mm): 1400×1200×2300 Net weight...
1, heat load: If enough test samples are placed in the working chamber of the thermal shock test chamber to affect the overall internal heat convection, it will inevitably affect the uniformity of the internal temperature to a certain extent. For example, when LED lighting products are placed, the...
The solution to the blockage of the spray hole of the rain test chamber: 1. Use mineral water for testing, and remove ash from the sample before testing to avoid bringing the tested water resources to the residue, which can prevent the appearance of dirt from the root...
Precautions for the purchase of thermal shock testing machine: First, we must select the thermal shock testing machine according to our product test items, and then check its impact temperature, test load, return time, defrost time, and whether the sensor is placed Meet the test standards of the product. Impact...
In the high performance liquid chromatograph analysis system, the requirements for column temperature control are getting higher and higher. Pharmacopoeias and many new analysis methods also provide conditions for column temperature, because the column can accurately and stably control the use of the...

1. Air circulation system of constant temperature and humidity chamber: the centrifugal fan is responsible for sucking in the air from the return air outlet, and the air passes through the steamer, humidifier, and electric heater, and after cooling or heating, dehumidification or humidification, it is sent to the...
low temperature test chamber Specific failure: The constant temperature and humidity test chamber frequently "jumps" during the day when it works, and the cooling effect is normal at night. low temperature test chamber Analysis: The refrigeration effect is normal at night,...
In the environmental test of solar cells, the humidity and freezing, temperature cycling, damp heat test, high and low temperature damp heat aging tests mentioned in the specification must be carried out. Confirm whether the solar cell fails or fails during the test. The failure of solar cells can be judged through...
①The deflation time should not be too long each time, it can be performed 2-3 times continuously to avoid wasting refrigerant. ②If there is a spare shut-off valve on the top of the condenser or accumulator, the air can also be discharged directly from the valve. high...
The working principle of high and low temperature chamber refrigeration: the refrigeration cycle adopts the reverse Karo cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor,...
The first step is to check whether there is water in the upper water tank of the constant temperature and humidity testing machine. If there is no water, then check whether there is water in the lower water tank; if there is no water in the upper and lower water tanks, you need to add water to the lower water tank...
