VOC Emissions Chamber
This system can test everything from plywood, wallpaper, curtains, and other building materials and automotive interior parts to everyday heat-generating home appliances, such as computers and printers. In addition, it is equipped with cable ports to electrify the specimen.
Choose from 2 different capacities (1m³ and 2m³) of the VOC Emission Test Chamber according to the size of the specimen. You can perform VOC emission testing in various fields, from compact specimens to large specimens.
In addition to having a clear air producing unit, this system uses stainless steel in the test area and reduces the amount of volatile organic compounds (VOC) generated from non-specimen materials. The test area is mirror finished and prevents the accumulation of VOC generated from the specimen for more accurate testing.
The ventilation count can be adjusted in the range of 0.2 to 2.0 times/hour (0.2 to 1.5 times/hour on VOC-020 only) according to test conditions.

External alarm terminal and specimen power supply terminal
External alarm terminal: This connection terminal provides external notification of an error when the safety device activates on the system.
Specimen power supply terminal: Electrifies the specimen. It consists of connection terminals.
Emergency stop switch
The system is equipped with an emergency stop switch. Pressing the emergency stop switch shuts down the chamber.
Rotating signal light
The system is equipped with a rotating signal light. This lights up and rotates when the system has a problem.
Time signal
Set this during program operation to control external equipment by opening and closing the circuit contacts. When an error occurs, the chamber stops and the contacts open.
Air compressor
This system is equipped with an air compressor to supply compressed air to the chamber.
Compressor: Oil-free scroll compressor (with built-in air dryer)
Air-circulating fan
The chamber comes with an air-circulating fan to improve temperature uniformity of the test area when a heat-generation load is generated in the compact chamber. Only one can be set at the prescribed location (front center interior of the compact chamber).
Chamber fastening bracket
This bracket secures to the floor to prevent the chamber from falling.
Cable port
The chamber comes with one cable port at a prescribed location at the left center of the unit.
Accessories
Compact chamber cable port (φ50 mm)
Test area cable port (φ100 mm)
Cap (φ50, φ100 mm)
Fluororubber plug (φ50 mm)
Silicon sponge rubber plug (φ100 mm)
* Air tightness cannot be guaranteed when passing equipment such as a power code through the cable port.
Plug sockets (external)
These sockets are used to electrify the specimen and supply power to peripheral instruments that are used in conjunction with chamber operation.
Power cord
5, 10m
