Description Overview Stack type humidity temperature control cabinet used for conditioning of samples prior to testing. Can also be used for a variety of materials of high-low temperature alternating test. Test temperature, humidity and time can be programmed. Bigger storage space and load heating value within same volume. Uses pwm cooling scheme when in low temperature operation. Avoids dew formation on the specimen. Equipped with detection system and wireless alarm system. Reliable and versatile, easy to use and maintain, high operational efficiency. Test Space Options Capacity: 80 liters, 120 liters, 150 liters. Inside dimension w x h x d (mm): 400 x 500 x 400, 400 x 500 x 600, 500 x 500 x 600. Outside dimension w x h x d (mm): 1050 x 1580 x 1640, 1050 x 1580 x 1840, 1150 x 1580 x 1840. Key Specifications Temperature range (optional, can be custom-made): -20 to 150°C, -40 to 150°C, -60 to 150°C. Humidity range: 20% to 98%, can be set. Rate of temperature increasing: room temperature to 150°C about 45 minutes (non-linear no-load, about 3.5°C/minute). Rate of temperature decreasing: room temperature to -20°C about 45 minutes (non-linear no-load, about 1.2°C/minute). Machine Precision Control accuracy (test precision): temperature +/-0.5°C, humidity +/-1% rh. Distribution accuracy (uniformity): temperature +/-1.0°C, humidity +/-2% rh.
