Shanghai Hengyue Medical Instruments Co. Ltd

Model Number: WJ-2-80 Brand Name: Hengzi Key Specifications/Special Features: Structure features:Water-jacket or air-jacket heating.High quality stainless steel working chamber.Forced convection for an even temperature and CO 2concentration.Convection and heating will be automatically off toprevent contamination when door is opened. (for WJ-3series, CO 2 inlet is also cut off)Temperature adopts microcomputer data analysis andP.I.D controller ,which is accurate and interference-free.( For water-jacket type, there are 3 sensors separatelyfor work room temperature, water temperature and door
temperature. For air-jacket, there are 2 sensors for work
room temperature and door temperature. )
Touch button, and digital display with LED indication.
Self protection for over-temperature, water-shortage and
gas-shortage.
Ultraviolet disinfection light tube to prevent
contamination.
Natural evaporation to guarantee the humidity in working
chamber
Gas Mixture:
WJ-2: Gas proportion type. The CO 2 gas and air are
mixed proportionally at will. The Direct reading with
needle valve glass rotameter is easy to read with
accurate scale.
WJ-3: The imported infrared CO 2 sensor which is gold
plated ensures the accuracy of the measurement.
Working life of CO 2 sensor is up to 15 years. CO 2
concentration is adjustable at will in the range of 0~20%
with the microprocessor data analysis and intelligent
P.I.D control. It also adopts alarm of over-concentration,
slow increasing of concentration , and gas shortage.
