Troubleshooting method 1. Imported sand and dust test box does not light up when the instrument is turned on and there is no power: check whether the power supply is normal, check whether the phase sequence is normal, and whether there is a neutral line. 2. Do not blow dust:...
In order to solve the customer’s worries and effectively reduce the company’s production costs, high and low temperature test chamber HUANYI instruments have maintained five mobile maintenance teams in various provinces and cities across the country. Each maintenance team is divided by region and area. Users...
HUANYI instruments adhere to the moderate market price of the high and low temperature test chamber (neither the lowest market price nor the highest market price). In terms of product quality, HUANYI Instruments insists on the high and low temperature test chambers developed and produced, using Korean ternary...
Although the temperature of the high and low temperature test chamber is not very high, the heat dissipation of the high and low temperature test chamber is still the first place. These environmental requirements are also applicable to other drying equipment: such as blast drying ovens, vacuum...
1. Non-heat-dissipation test sample and heat-dissipation test sample: After the temperature of the test sample is stable during the condition test, when measured under free air conditions (that is, without forced air circulation), the hottest spot temperature on the surface of the test sample is 5 degrees higher...
High and low temperature test chamber High and low temperature test is the most commonly used type of climate and environmental test. The high and low temperature test mainly assesses the environmental tolerance and environmental adaptability of the complete equipment, components, electronic components, etc....
In the daily test process, customers will find that the current of the refrigeration compressor of the constant temperature and humidity test box is large, which makes many users puzzled. The following are the points summarized by HUANYI instrument in many years of practice: 1. constant temperature and...
First, observe the pressure gauge on the back of the constant temperature and humidity test chamber to see if the pressure is within the normal range. If it is lower than the normal value, it means that the refrigerant is leaking. The refrigeration system of the high and low temperature test box must be leak-tested....
High and low temperature chamber body is processed by CNC machine tools, with beautiful appearance, non-responsive handle, and convenient operation. High and low temperature chamber The inner tank of the box adopts imported high-grade stainless steel (SUS304) mirror panel, and the outer...
Cooling is an important part of a constant temperature and humidity machine. It is important to determine the performance of a constant temperature and humidity machine. The high and low temperature test chamber is composed of compressor, condenser, throttling device and evaporator. The compressor is for...
When the tested product (component, component, component or complete machine) is placed in a constant temperature and humidity test chamber for testing, in order to ensure that the surrounding atmosphere of the tested product can meet the environmental conditions specified in constant temperature and...
In addition to the temperature, the most important thing about the constant temperature and humidity test chamber is the humidity system. If there is no humidity system, it will not be able to achieve damp heat, constant humidity and other related functions. Below we will carefully understand the effect of...
