Every purchaser will first assess what equipment the company needs to conduct the experiment. This is the primary task, and it is also a cognition. However, after the introduction of the network or friends around, I know which manufacturers with good reputation and high-end equipment quality know how to use the constant temperature and humidity test chamber at what ambient temperature and how to use it. Suitable and standard? Temperature: 5 ° C ~ +35 ° C (the average temperature within 24 hours should be ≤ 28 ° C); Relative humidity: is ≤ 85% RH; Air pressure: is 86kPa ~ 106kPa; Power supply conditions: It is a three-phase four-wire + protective ground wire, voltage range: AC (380 ± 38) V; The frequency is the range of allowable fluctuations: it is (50 ± 0.5) Hz; The grounding resistance of the protective ground wire is less than 4Ω; The user is required to configure the air or power switch of the corresponding capacity at the installation site, and the switch must be used independently for the device; Water supply conditions: The humidification water of the equipment needs to use pure water. The constant temperature and humidity test chamber cooling rate is common standard type, linear temperature drop and linear temperature drop. The normal temperature and humidity test chamber cooling rate standard is generally about 0.7 °C ~ 1 °C. Linear cooling means that the temperature drop rate is constant from the high temperature to the low temperature. The temperature drop of the nonlinear rapid temperature change tester is uneven from high temperature to low temperature. At the beginning, the cooling rate is fast, the closer to the set low temperature point, the slower the cooling rate is from the linear cooling rate (5°C/10°C/15°C/20°C/25°C)/minute, but not Linear cooling is up to 30 ° C / min. The linear and nonlinear cooling rate is faster than that of the ordinary constant temperature and humidity test chamber. Therefore, we refer to the latter two constant temperature and humidity test chambers as rapid temperature change test chamber, fast temperature change test chamber, and rapid temperature change test chamber. The relevant knowledge of the use of the constant temperature and humidity test chamber will be introduced to you, hoping to help you better master the use of constant temperature and humidity test chambers.
