Detailed Information
Convection current to right and left directions that provides stable testing environment
MARUI's neutralization acceleration apparatus creates convection current to fixed directions of right and left. So constant temperature, humidity, and CO2 density can be obtained in any part within the chamber.
The humidifier installed outside the testing chamber does not allow excessive CO2 intake and saves the costs.
In addition, drained water goes back to the humidifier to save water.

Electrostatic capacity type humidity sensor provides excellent humidity control
Conventional neutralization testing apparatus have used psychrometer type of humidifier to control humidity. However, that control method needs tremendous knowledge to constantly gain correct measurement values, as gauze (wick) handling, ventilation condition, water quality, temperature change, etc. may cause measurement unevenness. Also the gauze (wick) must be maintained and replaced when it has been damaged.
MARUI's neutralization acceleration apparatus uses electrostatic capacity type of humidity sensor to reduce the measurement unevenness or management work, and keeps a constant condition inside the testing chamber.
It measures water vapor adsorption by measuring electrostatic capacity changes and then converting to the humidity. It can also catch the change in electric capacity in low humidity and measure it.

Perfect CO₂ leakage prevention
A special double packing is used on the door part to prevent CO2 leakage.
In addition, it is designed with the "safety automatic locking function" not to accidentally open the door while testing operations.
