Product Description Product nameStep in Constant Temperature and Humidity test ChamberProduct descriptionIt is widely used in aviation, aerospace, automobiles, electronics, instruments and meters, electrical products, materials, components, equipment, etc. for high-temperature tests, low-temperature tests, cold resistance tests, and low-temperature storage, so as to analyze the performance and behavior under the proposed environmental conditions during the testsGb2423.1-2008/1 EC6008-2-1-2007 Test Methods for Low TemperatureGB/T2423.2-2008 Test Methods for High TemperatureGJB150.3A-2009 High Temperature Test MethodGJB150.4A-2009 Test Method for Low TemperatureGB2423.22-2008 Test Method for Rate of Temperature ChangeGBT2424.5-2006 Performance Confirmation of Temperature Test ChamberGB/T10586-2008 Technical Conditions for Low Temperature Test ChambersGB/T2423.3-2008(1EC68-2-3) Test Method for Constant Damp HeatGJB150.9A-2009 Wet Heat Test MethodG/BT2423.4-2008/1EC6008-2-30:2005 Alternating Wet Heat MethodGB/T5170.18-2005 Verification Methods for Basic Parameters of Test EquipmentTechnical Conditions for Wet Heat Test Chambers GB/T10586-2006GBT2424.6-2006 Performance Confirmation of Temperature and Humidity Test ChamberGBT2424.7-2006 (with Load) Temperature Test chamber measurement Detailed parametersModel:LT-BTH-8000(T~S)LT-BTH-10000(T~S)LT-BTH-20000(T~S)LT-BTH-30000(T~S)LT-BTH-40000(T~S)Internal dimensions WxHxD (m)2.0x2.0x2.02.5x2.2x2.04.0x2.0x2.54.0x2.5x3.04.0x2.5x3.2External dimensions WxHxD (m)3.0x2.3x2.23.6x2.3x2.265.1x2.3x2.765.1x2.8x3.36.1x2.8x3.5Temperature range-70oC~+150oC ( T:-20oC F:-40oC S:-70oC)Humidity range20%~98%R.H.(10%-98%R.H/5%~98%R.H For special selection conditions)Accuracy/uniformity of temperature and humidity analysis±0.1oC;±0.1%R.H./ ±1.0oC;±3.0%R.H.Temperature and humidity control accuracy/fluctuation±1.0oC;±2.0%R.H./ ±0.5oC;±2.0%R.H.Heating/cooling timeAbout 3.0oC per minute; Approximately 1.0oC per minute (a decrease of 2 to 10oC per minute is a special selection condition)Internal and external materialsThe outer box is made of SUS304# stainless steel with surface stripe treatment or cold-rolled steel plate with baking varnish treatment (optional), and the inner box is made of SUS304# stainless steelThermal insulation materialHigh-temperature resistant and high-density ethyl chloroformate foam insulating materialCooling systemAir-cooled/single-stage compressor (-20oC to -40oC), air-water-cooled/double-stage compressor (-40oC to -70oC)Protective deviceFuseless switch, compressor overload protection switch, refrigerant high and low pressure protection switch, over-humidity and over-temperature protection switch, fuse, fault warning systemAccessoriesRecorder (optional), viewing window,50mm test hole,PL box lamp, partition, dry and wet bulb gauzeControllerYou can choose either "TEMI" South Korea or "OYO" Japan's "OYO" BrandCompressorThe French brand "Tecumseh"PowerAC380V 50HZ/60HZ RemarksFor volumes under 10 cubic meters, it can be selected to be made as a movable whole machine structure or a panel assembly structure. For volumes over 10 cubic meters, it is all a panel assembly structure Machine parametersAppearanceDifferent colors can be matched according to the interior design or a fully stainless steel design can be chosen. The interior space is made of SUS304# stainless steel at 30% to 70%. Rectangular double-pane glass viewing windowIt can be used for observing the test samples during the experiment. The window is equipped with an anti-sweat electric heater device to prevent water vapor condensation and water droplets. Install explosion-proof lamps indoorsDuring the test, the product test status can be clearly observed. Anti-slip aluminum plates are installed at the bottom of the test laboratory for safe use.Another layer of heat insulation sealing strip is placed on the box door,It can effectively prevent the leakage of internal temperature Pure water filtration unitIt can be directly used for filtering tap water without the need for manual water addition, making it very convenient to use Refrigeration and dehumidification systemIt adopts imported brand compressors, featuring energy conservation, low noise, low energy consumption and stable performance. It uses environmentally friendly refrigerants (R23, R404a). ControllerIt adopts an imported LCD display screen, which can simultaneously show the measured value, the set value, time, etc.It features multi-segment program editing and allows for QUICK or SLOPE control of temperature and humidity TEMI2700 watch7.5-inch true-color LCD display with RS-232/RS-485 communication interfaces and 2GB standard SD memory card, which can be connected to Ethernet for use. TEMI880 meter 5.7-inch color display with RS-232/RS-485 communication interfaces (optional as required) The bottom of the machineThe load-bearing capacity is increased by welding channel steel into a mesh structure, which will never deform during use. The bottom of the integral laboratory is equipped with mobile casters to position the foot cups, while the bottom of the assembled laboratory is directly installed on the laboratory floor with channel stee
