GQ-300 Modified Atmosphere Refrigerator
Introduction
GQ-300 Modified Atmosphere Refrigerator, with microelectronics technology, is for making preservation experiment on fruits, vegetables, flowers and plants in modified atmosphere conditions, and keeps them fresh by controlling concentration of O_2,N₂, CO₂, and C₂H₄ and the temperature and humidity in the boxes. It is widely used in industries of microorganisms, environmental, food, research institute and so on.
Features
1.  Hardware and software
The product consists of controlling section, implementing section and workroom. The control section can set a variety of parameters (including temperature, humidity, gas concentration, etc.), to meet the growth requirement of different animals and plants and the preservation needs of various living things.
Three test chambers. Each chamber independent controlling system, illumination system and sterilization system (With ultraviolet disinfection and ozone sterilization function).
The workroom is made of stainless steel plate with surface of spray plastics, so it is of great antirust performance.
lImported precise sensors ensure wide test range and high accuracy.
Configured with: transparent window, sterilization system, built-in headlight and self-occlusive design cabinet.
Can automatically record the respiratory status of fruits and vegetables and check data handily. Computer-controlling system is optionally available and can save historical records.
Real color touch screen displays the parameters and results visually.
With software, real time monitor and continuous record of gas composition, temperature and humidity; can achieve distant monitoring.
Online analysis system is optionally available.
2.  Temperature control
Adopts quartz tube to heat up and scroll compressor to cooling down, so the temperature can be risen and lowered quickly, with high performance and little noise.
PID algorithm works together with solid relay to control the heating tube, controls the temperature precisely, evenly and constantly, without rigid mechanical contacts and with long lifetime.
3.  Humidity control
High frequency atomization humidification provides large humidification range and stable humidity. Can humidify for a long time without getting hot.
The humidifying system of each chamber works independently. Automatically humidifies after setting the humidity parameters, reach the set humidity and stay at that humidity constantly.
4. Gas control
Automatically control the concentration, temperature and humidity of the gases.
Accurate flow controller (resolution ratio: 0.01ml/min) controls the gas flow exactly.
With ethylene eliminating device and gas substituting pump, controls the concentration of ethylene effectively.
Two ways to provide nitrogen: gas cylinder or nitrogen generator. High-power nitrogen generator (3 m³/h, purity>99.5%) is more cost-saving.
Auto replacement of gas, fast removal.
