Product Description Product Description HY-831C desktop constant temperature and humidity testing machineTechnical Parameters1.Equipment performance:Humidity range: 20% to 95%Temperature range: -20-150°CTemperature stability: ±0.5°CHumidity stability: ±3%Inner box size: 400*400*500mmOuter box size: 900*900*1000mm2. Structural design:Inner box material: stainless steel plate ( SUS # 304 ),Outer box material: stainless steel surface brushed.Observation window: to observe the sample ( W*L 28 * 35 cm )×1Outer box light source: high-brightness lighting ( 13 W PL lamp )Anti-sweat window design: electric heater device to prevent condensation ( 40 W )Test hole: can be used for external test power line and signalMachine pulley: move the pulley to adjust the placement position and fix the position with strong bolts (200Kg / wheel)Insulation layer: flame-resistant and fire-resistant PU + heat-insulating glass wool (thickness of insulation layer: 10.0 cm)Pan frame in the box: movable adjustable grid pan frame and two stainless steel strip grid pans (5.0 cm for each grid of the pan rack, plus a non-conductive sleeve)Box door: double-channel heat-insulated and air-tight tight, which effectively isolates external temperature leakage3. Temperature electric heating cycle system:Electric heating circulation system: special moisture-proof and heat-dissipating design for temperature, stainless steel extended axis circulation motorCirculation fan: high/low temperature resistant aluminum alloy multi-blade circulation fanAir deflector design: adjustable air deflector design, effectively improve the uniformity of temperature and humidity distributionTemperature electric heater control method: balanced temperature adjustment P.I.D + P.W.M + S.S.RHumidity electric heater control method: balanced humidity control P.I.D + P.W.M + S.S.R primary and secondary double U-shaped humidity electric heater4. Refrigeration system:Refrigeration device: French Taikang high-efficiency power-saving ultra-low temperature refrigeration system (air-cooled heat dissipation method)Cooling and heat exchange device: Adopt ultra-high-efficiency SWEP cold coal cold and heat exchange design, which is more efficient than the traditional internal spiral type.Heating load adjustment: The mining computer automatically adjusts the flow of cold coal, effectively taking away the heating load of the product to be tested and synchronizing with German/Japanese technology.Compared with the traditional design, the control stability and reproducibility are higher, and the power saving and low humidity performance are achieved.High-efficiency components: condenser and evaporator adopt AC&R compound spoiler aluminum fin deviceLow-humidity design: using slope evaporator and dew point dehumidification control method (WDP)Moisture-proof design of the door wall: high-pressure compressor and high-temperature pipeline, sweat-proof and moisture-proof treatment.Standard modular design: high compatibility and high quality stability of interoperable parts and components.Expanded performance: HY600 control system can reserve isothermal control liquid nitrogen valve LN2V & refrigerant valve5. Control system:Temperature and humidity sensor: JIS RTD PT 100 Ω × 2 (platinum sensor)Temperature and humidity converter: microcomputer multi-function automatic linear compensation correctionDisplay surface: board color liquid crystal TFT LCD 5.7 " temperature and humidity setting (SV) and actual (PV) value are directly displayed.Operation interface: touch type (withstanding 100.000 times of line drawing test), Chinese and English can be switched arbitrarilyStorage device: USB2.0 interface, USB storage capacity supports up to 32M U diskProgram group: maximum 120 PATTEN.Program segment: 1200 SEGMENTS in totalProgram cycle: each command can be up to 999 times.Automatic control: refrigeration compressor, servo valve, temperature and humidity electric heating, PID, PWM, SSR ... etc. The safety detection device detects the failure of each part and alarms to stop.Other configurations: running cumulative time function; temperature and humidity program setting values are displayed in graphic curves, with real-time display program curve execution function; fault prompt screen display; program production adopts dialogue mode, with editing, clearing, inserting and other functions; SEGMENTS Time setting 0~99Hour59Min.; with power-off program memory, automatically start and continue to execute the program after power recovery; with scheduled start and shutdown functions; with date and time adjustment functions; key and screen lock (LOCK) functions.6. Safety protection system:Leakage/surge protection: LG leakage circuit breaker leakage protection FUSE. RC electronic surge protectionThe controller is protected against power supply lightning strikes: the primary side of the AC power supply of the controller is equipped with a lightning arrester ZRN deviceHumidity sensor (Sensor): open circuit or short circuit ( + - OVER )The first layer of high/low temperature over-temperature protection: operation control temperature high, low temperature over-temperature protection settingFault detection control interface: external fault automatic detection protection deviceThe second layer of high-temperature over-temperature protection: electronic high-temperature over-temperature protection deviceThe third layer of high temperature over-temperature protection: high temperature over-temperature protection deviceWater cut-off and air burning protection: humidity water cut-off protection and electric heating water cut-off and air burning protectionCompressor protection: refrigerant pressure protection and overload protection device.Expansion protection device: reserve two sets of fault detection input expansion protection device for useFault exception protection: cut off the control power supply and fault cause indication and alarm output signal when an abnormal fault occursActive water shortage prompt: the machine will automatically prompt for water shortage.Dynamic high and low temperature protection: dynamically adjust the high and low temperature protection value according to the set conditionsNormal temperature protection: After the machine stops, the product under test and the test area will automatically drop to normal temperature protection.Operating instructions, maintenance manuals, circuit diagrams, CD-ROMs, calibration reports, guarantees, maintenance record cards, personnel training7. Matters needing attention:1. The ambient temperature around the machine is maintained between +5°C and +30°C;2. Your factory is responsible for the construction of hydropower, water towers, civil engineering, etc. and connects them to the machine3. Power supply: AC 380V 50HZ 3∮ 5 wire 7.5KWA Execution StandardsGB/T2423.1-2008, GB/T10589-2008; GB/T2423.2-2008; GBR11158-2008; GBIT2423.3-2006; GB/T10586-2006; GB/T2423.22-002;Company Profile Founded in 2003, Hengyu Instrument is headquartered in Dongguan City, Guangdong Province.
