Overview
HUITAI LHS-250SCN + RS485 interface Constant Temperature and Humidity Chamber is an environment simulation equipment that provides precise temperature and humidity control. It provides various environment simulation conditions required for industrial research and biotechnology testing, and can be widely used in Spinning & weaving, Food processing and other aseptic tests, Stability inspection, and industrial product raw material performance, product Encasement, product life and other tests.
Features
1. Humanized design: large-screen LCD display, one-screen display of multiple sets of data, menu-style operation interface, simple and easy to understand.
2. Environmental protection and energy saving: use 134a without fluorine refrigerant, effective and energy saving.
3. Easy to clean structure: mirror stainless steel liner, four corners and half arc design, adjustable shelf spacing.
4. Adjustable wind speed: The wind speed of the equipment fan is adjusted in'fast and slow 'gears to prevent the sample from losing moisture too quickly.
5. Save space: The instrument control of the whole machine is placed in the upper left corner of the door panel, and the whole machine is beautiful and elegant, saving space for placement.
6. Insulation observation: The double-decked door structure is used, and the thermal insulation performance is good. It does not affect the temperature in the box when observing the situation in the box.
7. Easy to test: There is a 25mm diameter test hole on the left side of the box, which is convenient for experimental operation and temperature measurement.
8. Durable and easy to clean: the overall surface of the box is sand blasting, not easy to scratch.
9. Reliable core components: the use of brand Compressor, independent research and development of Compressor cooling system, can effectively extend the service life of the Compressor.
10. Uniform temperature field: using JAKEL tube flow circulating fan, coupled with a unique design of the air duct structure, to create a good air circulation system.
11. Accurate humidity control: Adopt international good brand humidity Sensor, self-designed built-in water tank electric heating tube humidification system.
12. Precise control: PID Control mode, temperature control, humidity control accurate fluctuations.
13. The program is powerful: with 99 cycles of programs, each cycle is divided into 30 sections, each section is 99 hours and 59 minutes of cycle steps, which can satisfy almost all complex experimental processes.
14. Safety options: An independent temperature limit alarm system can be selected. If the temperature exceeds the limit, the operation will be automatically interrupted and sound and light alarms will be issued.
15.Easy data processing: standard RS485 interface, can be connected to a printer or computer, can record the change of temperature parameters.
Principle
The equipment precisely regulates the environment in the box through the built-in refrigeration system (using brand Compressor and 134a without fluorine refrigerant), heating system and humidification system (built-in water tank electric heating tube humidification). The PID control algorithm is used, combined with the feedback of High Accuracy Temperature and Humidity Sensor, to achieve precise and stable control of temperature and humidity. The air in the box is forced to circulate through the JAKEL pipe flow circulation fan and the unique air duct structure to ensure uniform temperature and humidity at all points in the box.
Applications
Spinning & weaving, Food processing and other aseptic tests, Stability inspection, Raw material performance testing of industrial products, Product Encasement testing, Product life testing, Biotechnology testing, Industrial research
Standards
The data did not mention specific compliance criteria.
Steps
1. Connect the AC220V 50Hz power supply.
2. Set the required temperature, humidity, program cycle and other parameters through the large-screen LCD menu operation interface.
3. Adjust the shelf spacing in the box and place the sample as needed.
4. According to the experimental requirements, select the'fast 'or'slow' gear of the fan wind speed.
5. Start the device to run.
6. Experimental operation or measurement can be carried out through the test hole on the left side of the box.
7. During or after the experiment, a printer or computer can be connected to record data through the RS485 interface.
Notice
The input power of the device is 1950W, please ensure that the power supply meets the requirements of AC220V 50Hz and has the corresponding load capacity.
• Temperature range is 0~ 65 ℃, humidity control range is 40~ 95% RH, do not use outside the range.
• When placing the sample, please be careful not to block the air duct, so as not to affect the uniformity of temperature and humidity in the box.
• Using a slow wind speed gear helps prevent the sample from losing moisture too quickly.
• When observing the situation in the box, please observe through the double-decked door to minimize the opening time and times to keep the environment in the box stable.
• Regularly clean the mirror stainless steel liner to keep the equipment hygienic.
• For key experiments with overtemperature risk, it is recommended to choose an independent temperature limit alarm system to ensure safety.
When connecting to the RS485 interface for data transmission, please use dedicated software.
