As a professional manufacturer of high and low temperature test chambers, based on our accumulated experience over the years, our company now briefly describes the environmental conditions of the on-site installation of high and low temperature test chambers for everyone to share. 1. Main technical indicators of high and low temperature test chamber: 1. Temperature range: -70 ℃, -40 ℃, -20 ℃ ～ + 150 ℃ 2. Temperature fluctuation: ± 0.5 ℃ 3. Average temperature: ≤ ± 2 ℃ 4. Rate of temperature rise and fall: 0.7 ～ 1 ℃ / min (can be customized according to customer requirements) 5. Heating rate: 2 ～ 3 ℃ / min 2. The premise of using the high and low temperature test chamber on site 1. Temperature: 15 ℃ ~ 35 ℃ 2. Relative humidity: not more than 85% RH 3. No strong vibration or strong electromagnetic field nearby 4. There is no high concentration of dust and aggressive substances nearby 5. No direct sunlight or direct radiation from other heat sources 6. There is no strong airflow nearby. When the nearby air needs forced flow, the airflow should not be directly blown onto the box. 7. The test chamber should be placed steadily and kept level. 8. There should be a certain interval around the test box to facilitate maintenance and operation. 9. The installation site is well ventilated 10. Single phase (220V 50Hz) 3KW 11.
