Detailed information

• 

  With a left-right convection structure, a stable testing environment is achieved. Marui's neutralization testing device circulates air adjusted in the air conditioning chamber in a consistent left-right direction within the testing tank, allowing for stable temperature, humidity, and CO2 concentration at any position inside the tank. Additionally, by placing the humidifier outside the testing tank, there is no excess CO2 intake, resulting in cost savings. Furthermore, the structure allows drain water to return to the humidifier, contributing to water conservation.

• 

  The capacitive humidity sensor offers excellent humidity management accuracy. In neutralization testing machines that manage humidity using a wet and dry bulb hygrometer, there is a possibility of errors due to factors such as handling of gauze, ventilation conditions, water quality, and temperature fluctuations. Achieving consistently accurate measurements requires considerable expertise, and there is also a need for management and replacement to prevent the deterioration of the gauze. Marui's neutralization testing equipment employs a capacitive humidity sensor, eliminating such measurement errors and management hassles, allowing for stable conditions within the testing chamber at all times.

• 

  Measures against CO2 leakage are thorough. Double special gaskets are used in the door section to prevent CO2 from leaking. Additionally, with the "automatic safety lock feature," the structure is designed with safety measures in mind to prevent accidents from inadvertently opening the device door during testing.
