Matters needing attention when measuring high and low temperature alternating heat and humidity test chamber
The high and low temperature alternating heat and humidity test chamber, also known as the “constant temperature and humidity test chamberâ€, belongs to the high and low temperature series. It is an indispensable test equipment for aviation and scientific research. It is used to test and determine the high temperature of electrical, electronic and other products and materials. What are the problems we should pay attention to when making measurements, low temperature, alternating damp heat or constant test temperature and environmental parameters?
1. When reading the hygrometer indication value of the high and low temperature alternating heat and humidity test chamber, the front and back time should be as short as possible. It is best to read at the same time at three points, and pay attention to the uniform vision of the reader. For the same thermometer, read the wet bulb temperature first.
Second, the temperature and humidity curve automatically recorded by the temperature and humidity meter configured inside the equipment, the fluctuation of the data should be basically consistent with the data measured by the hygrometer, otherwise the record is considered inaccurate. The temperature and humidity of the constant temperature and humidity test chamber meet the standard requirements, and the recorded temperature and relative humidity must be within the allowable limits at all times.
3. When reading the indication of the hygrometer, objects that are different from the temperature of the device, such as the hands and faces of the human body, should be kept away from sensitive mercury spheres.
The inner liner of the high and low temperature alternating heat and humidity test chamber is made of imported SUS304 stainless steel plate. The spray is ultrasonic humidification, high power compressor, double vacuum glass door, temperature and humidity digital display intelligent instrument can be installed with micro printer, it is laboratory, quality inspection. The best equipment for the center to test the parameters and performance of the product.
