Overview
HUITAI LHS-250HC + RS485 interface Constant Temperature and Humidity Chamber is a precision environment simulation device with a volume of 250L. It uses a large-screen LCD display and mirror stainless steel liner, Temperature range -5~ 80 ℃, humidity control range 40~ 85% RH, PID control to achieve accurate temperature and humidity adjustment, with small fluctuations. The box adopts double-decked door structure, which has good thermal insulation effect, and comes standard with RS485 interface for data recording.
Features
1. Humanized design: large screen LCD display, menu operation interface; environmentally friendly without fluorine refrigerant; mirror stainless steel liner, four corners and half arcs are easy to clean, shelf spacing is adjustable; double-decked door structure, good thermal insulation performance; optional test hole and box door observation window.
2, quality assurance: using brand Compressor and self-developed cooling system; JAKEL pipe flow circulating fan and unique air duct to ensure the temperature uniformity in the box; using international good brand humidity Sensor and built-in water tank electric heating tube humidification system to effectively ensure humidity deviation; PID Control mode, temperature control and humidity accurate; support 99 cycles, 30 sections per cycle of complex program settings.
3. Safety and data processing: Optional independent temperature limit alarm system, automatic interruption and alarm over temperature; standard RS485 interface, can be connected to a printer or computer to record temperature parameter changes.
Principle
The equipment uses the Compressor cooling system and the electric heating tube humidification system to cool and humidify the environment in the box respectively. The PID control algorithm is used to precisely adjust the temperature and humidity, and the air in the box is evenly circulated through the circulating fan and the unique air duct structure to maintain the set constant temperature and humidity conditions. RS485 interface is used for external equipment connection to realize data monitoring and recording.
Applications

Steps
1. Connect the AC220V 50HZ power supply.
2. Set the required temperature, humidity, and program (if necessary) through the large-screen LCD menu-type operation interface.
3. Place the sample and adjust the shelf spacing in the box.
4. Start the device running.
5. A computer or printer can be connected through the RS485 interface to monitor or record changes in temperature and humidity parameters in real time.
6. After the experiment is completed, shut down the equipment according to the procedures.
Notice
● The equipment should work under the conditions of environment temperature of 20 ℃, environment humidity of about 50% RH, no strong magnetism and no vibration to ensure accurate performance parameters.
● Pay attention to the equipment Temperature range (-5~ 80 ℃) and humidity control range (40~ 85% RH), do not use beyond the range.
The optional independent temperature limit alarm system can automatically interrupt the operation when the temperature is exceeded. It is recommended to choose according to the experimental safety requirements.
● When cleaning, please note that the liner is made of mirror stainless steel, and avoid using sharp or corrosive cleaning tools.
● When conducting experimental operations and measurements, the optional test hole on the left side of the box can be used to reduce the impact on the environment in the box.
● Non-standard volume products can be customized according to user requests.
