Manually switch the cavity to display the temperature and humidity of each cavity, as well as the concentration of oxygen, nitrogen, carbon dioxide, ethylene, and so on.   24 inch 100,000 real color touch screen, can set the parameters of each cavity and control operations respectively; Detailed data and work status are displayed in real time.  Built-in ozone sterilization, manual button sterilization, can set the sterilization time.  Built-in ethylene catalytic removal device and gas displacement pump control ethylene concentration, fast degassing speed.  Imported high-precision sensors to detect various gas concentrations and ethylene concentrations. The sterilization system adopts ozone sterilization, the manual button for sterilization, automatic control of sterilization time, and automatic stop when the set time is reached. Temperature control: using heating wire heating, scroll compressor cooling, stable performance, low noise; PID algorithm with solid state relay control, no hard mechanical contacts, long service life, average temperature heating, constant temperature. The temperature control of each chamber adopts unified control, and the temperature of the three chambers is set manually. Humidity control: high-frequency atomization humidification, the humidification range is large, long-term humidification does not heat, does not affect the cavity temperature; Each chamber humidification system operates independently, automatically humidifies and maintains humidity after setting the humidity. The inner wall of each cavity is made of stainless steel, the special double-layer glass door, and the shell is made of special color steel plate.  Transparent windows, drainage system anti-condensation, built-in lighting, and self-entry box design.

Application W301 2.0 water vapor permeability analyzer is designed to test the water vapor transmission rate (WVTR) of films or sheets materials with the principle of Gravimetric Method.

GB-MH180 Respirator Fit Test Machine is a specialized instrument for measuring leakage ratio of dust concentration quantitatively in and out of mask to select fitted mask and check leakage, which is compatible with the requirements of OSHA and GB 19083-2010 .The Respirator Fit Test Machine is widely used in workplaces such as hospitals, manufacturing plants, production sites, and other testing institutions.  

GC9802-K Face Mask Ethylene Oxide (EO) Residuals Testing Gas Chromatography has a reasonable structure, stable and reliable performance, simple operation and convenient maintenance. Can be widely used in petroleum, chemical industry, pesticides, medicine and health, commodity inspection, environmental protection, universities and other production and scientific research departments. It can be used to detect ethylene oxide and other organic solvents. Detects purity or content of a single solvent

Test Principle Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.
