Note: The size can be customized according to the actual requirements of the user.
The equipment meets the following testing standards
National Standard/T2423.1-2008 Test A: Low Temperature National Standard/T4243.2-2008 Test B: High Temperature (Partial) National Standard/T2433.3-2006 Test Cab: Constant Humidity and Heat Chinese National Standard/T2423.4-2008 Test. Decibel: Change, Damp Heat China National Standard/T2423.34-2012 Test Z/AnnoDominique: Temperature and humidity combination or other temperature and humidity tests within the equipment performance range.
Structure of the testing chamber
The outer shell of the test box is made of galvanized color steel plate.
The inner boxes are all made of SUS304 stainless steel plates; There is a hanging hole strip on the side of the two inner boxes that can be uniformly adjusted up and down, with a test track frame; At least 10 thermal insulation layers Cm rigid polyurethane foam and glass wool thermal insulation interlayer; The connection between the front doors of the inner and outer boxes adopts high-quality electric wood chicken glass fiber board door frames as thermal insulation partitions, which have excellent low-temperature insulation performance; The sealing strip on the door is a series of silicone foam with double channels and wide temperature resistance.
Experimental space air circulation:
The mature air supply system adopts multi blade aluminum wind turbines that are resistant to high and low temperatures, driven by motors, to deliver air to the upper louvers. The wind returns from the bottom, with a uniformity of less than 2 º C within the range of -70~100 º C; (Divided by 10 points internationally).
Controller operating system
Adopting the original low-power (8W) temperature and humidity control device, the temperature control accuracy can reach ± 3 º C.
1. High resolution screen:
Displayed as 7-inch TET. True color LCD resistive touch screen with a resolution of up to 800 * 480.
2. High program capacity:
Memory capacity: 1000 programs/1000 segments, 999 total loops, 999 partial loops; 10 sets of program linking functions; And there is real-time temperature curve display, which can be directly queried.
3. High data storage capacity:
Transfer the historical data of 300 days under storage operation status by directly uploading the hard disk or network cable to the computer or loading it into the controller.
4. Easy connection:
The controller adopts LAN standard Ethernet communication, and one software can connect up to 16 devices at most; Through the outflow interface of the machine, it is easy to connect to the regional network and achieve remote program control functions such as real-time monitoring and historical curve playback.
Heating and humidification system
Bare wire nickel chromium alloy electric heating tube, with low thermal inertia, small heating overshoot, and high precision fluctuation guaranteed by power.
1. Humidifier:
Using a humidification cylinder (boiler method) for humidification is more uniform. Surface humidification (water plate method) has faster speed and higher control accuracy, and there will be no impurities such as scale inside the box. Dyeing, good low humidity performance, easy to clean; The humidification tube adopts a seamless stainless steel shell, with an insulation resistance greater than 50M Ω, and is equipped with an anti dry burning controller.
2. Water consumption and energy conservation:
Front mounted 25L large capacity water tank with quick connection design for water and electricity plugging, easy to disassemble and clean: precise dehumidification control in three humidity zones, saving water consumption, and meeting national standards for high temperature and humidity such as 85 º C and 85% RH. The point cooling and dehumidification system is turned off. The closed design greatly reduces water consumption.
Purchase equipment that meets extreme testing conditions
1. Selection of circulating air mode: courtyard air supply or variable speed motor
If your product has special requirements for wind speed, this solution is your best choice.
2. Water supply system selection: RO reverse osmosis
When our equipment needs humidification, we need to use pure water. This automatic water production method can continuously provide pure water, saving time and achieving convenient results.
3. Polymer film/rotor dehumidification system
If long-term low-temperature and low humidity test conditions are your necessary requirements, then a cellular chemical dehumidification system is your inevitable choice, with a humidity range of up to 10 º C/10% RH or lower requirements.
4. LN.Two/ .LCO.2
We offer professional products with complete specifications imported from Europe and the United States. LN.Two/ .LCO.2
solenoid valves and related control systems to meet your rapid testing requirements for acceleration and temperature reduction.
5. Ultrasonic cooling and humidification system
If you have to perform dynamic testing of high heat load under high temperature and high humidity, then ultrasonic cooling and humidification system is the system that meets this strict requirement. It needs to be equipped as an auxiliary device.
6. Add a glass inner door and attach a manual operation hole
For the frequent movement and start-up of the tested object, adding manual operations related to the glass inner door (∧ 125Mm * Ea.) can eliminate the impact of the testing environment caused by the opening of the box door.
7. A recorder for real-time acquisition of test data
When multiple temperature measurements of both the testing environment and the tested object need to be recorded simultaneously, add records that comply with the specifications. A tape recorder is the only option that meets the demand.
8. Computer connection operation recording software
When the connection software is tailored for Mattel's environmental measuring machine kitchen, its powerful features can simultaneously monitor multiple machines, access data from operating machines, and provide the most convenient and advanced electronic functions for users.
