Product features: 1. the box body adopts polyurethane board with good thermal insulation performance. The inner surface is stainless steel and the surface is color steel plate, which is durable and beautiful. 2. the observation window adopts the anti nebulization function to facilitate the observation of the sample during the test. 3. display control device using text display or touch screen. 4. the air duct inside the box is carefully designed to ensure that the air distribution in the box is evenly distributed. 5. the pressure balance device in the box ensures deformation of the box wall due to thermal stress. 6. has multiple protection functions: overtemperature protection, over-current protection, high and low voltage protection, anti dry burning protection, overload protection and other protection measures, ensuring the safe and reliable operation of the equipment (specific function is determined by the equipment model). Technical indicators: Temperature range: -20,40,60,70 C ~60, 80100120 C (basic customer requirement design) Precision range: temperature is + 0.1 C Indication precision: temperature + 0.1 C Temperature deviation: less than or equal to 2 degrees C (difference between setting temperature and actual temperature difference between workplaces) Temperature fluctuation: 5 degrees centigrade Power supply voltage: AC380 (+ 10%) V/50HZ three-phase five wire system Ambient temperature: 5 ~ + + 28 C (average temperature in 24 hours is less than 28 C). Ambient humidity: less than 85%
