Product Description 225L Programmable Temperature and Humidity Test Chamber Thermal Test ChamberTemperature humidity test chamber is used to test various types of materials for their tolerances of heat, cold, dry, humidity. It is applied for quality inspection for all types of electronic products, electric appliance, and products from communication, instrument, automobile, plastic, metal, food, chemical, building materials, medical and aerospace industries. Temperature and humidity testing help to determine the behavior of the components in severe test conditions and environments that involve fluctuatingenvironment, high temperature, and different relative humidity. The tests can be done with constant temperature and humidity in a static state and can bedone in a dynamic state where the moisture is used to induce a failure of the components or materials.Main Features1.The constant temperature and humidity test box is mainly composed of control panel, distribution panel, insulation layer, air supply fan, heater, humidifier and refrigeration unit. The main specifications can be divided into 6 standard sizes and 10 specifications under different conditions.2.The controller can be connected to the computer through LAN interface. Users can design programs on the computer screen, collect test data and records, call program execution, remote control machine switch and other functions.3.The use of multi-wing air supply fan strong air circulation, to avoid any dead angle, so that indoor temperature and humidity distribution is uniform.4.Complete safety protection device, if abnormal conditions occur, the controller screen will automatically display the fault status, cut off the power switch, and provide troubleshooting methods.Model AvailableModel TMAX-80(A~F) TMAX-150(A~F) TMAX-225(A~F) TMAX-408(A~F) TMAX-800(A~F) TMAX-1000(A~F) Internal DimensionWxHxD (mm) 400x500x400 500x600x500 600x750x500 600x850x800 1000x1000x800 1000x1000x1000 Internal Dimension WxHxD (mm) 950x1650x950 1050x1750x1050 1200x1900x1150 1200x1950x1350 1600x2000x1450 1600x2100x1450 TemperatureRange Low Temperature(A:25°C B:0°C C:-20°C D:-40°C E:-60°C F:-70°C) High Temperature 150°CThe temperature range can be customized/selectable HumidityRange 20%~98%R.H.(10%-98% R.H. / 5%-98% R.H ,is a special optional condition, need Dehumidifier) Analytic Accuracy/Distribution uniformity oftemperature and humidity 0.1°C; 0.1% R.H/±2.0°C; ±3.0% R.H.A.Testing ParameterTemperature range-70oC~+150 oC(Air-cooled type)The temperature range can be customized according to your actual needsHumidity range20%-98% RH (the distribution range is as follows) The cooling rate (no-load)About 1oC/minThe heating rate (no load)About 3oC/minTemperature stability±0.5oCAnalytical accuracy of temperature0.01oCPrecision of humidity control±2%R.HTemperature uniformity ±2.0oCHumidity uniformity≤±3%R.H(+2,-3%RH)Working noiseA sound level is less than 75 dB (A) (measured in a soundproof room with 25 C ambient temperature and less echo; measured the average value of 8 points by A weighting; measured the level of each test point is 1 metre from the noise source and the height is 1 metre from the ground).B.Machine StructureMaterial of inner and outer boxesSUS # 304 Outer box light sourceHigh brightness lampStructural design of stratosphereEffective avoidance of condensation at the top of the boxObservation WindowObservation sample use (W*L 28*35 cm)Anti-sweat design of windowsElectrical heating device to prevent condensation of water and gas (40 W)Test Holes Can be used for connect external test power cord and signal (diameter 50 mm)Machine pulleyPulleys are movable and positioned with strong bolts (200Kg/wheel)Insulation LayerRigid polyurethane foam (its advantages are: 1. High efficiency and energy saving, seamless after filling, strong bonding after curing.2. Seismic and compressive resistance, no cracking, no decay, no falling off after solidification.3. It has ultra-low temperature heat conductivity, weather resistance and heat preservation.4. High efficiency insulation, sound insulation, waterproof and moisture-proof after curing.5. waterproof performance is good, because the foam hole is closed, the sealing rate is 95%, and the rainwater will not permeate through the hole.Inner rackMovable adjustable grids and two stainless steel strip grids (5.0 cm per grille) Box door Double-channel heat insulation and tight gas to effectively isolate external temperature leakageC.Safety Protection SystemLeakage/Surge ProtectionFUSE.
