Choose from two types of test areas

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.

Supports various measurement specimens

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.

Interactive input system for easy operation

The instrumentation has a color LCD screen and uses an interactive input system with touch operations to enable easy settings by anyone.

Ensures a TVOC value of at least 20 μg/m³ for the background concentration

The VOC Emission Test Chamber uses material with low organic emission and low adsorption, and it comes with a high performance clean air producing unit that removes unneeded gas in the air. It constantly provides clean air and ensures a TVOC value of less than 20 μg/m³ for the background concentration prior to test start.



VOC-1000 (air-circulating fan is provided as option)



VOC-2000

Accurate measurement

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.

Adjustable the ventilation count according to test conditions

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.




Paperless data recording

The paperless recorder enables recording of the test area temperature, humidity, and air exchange rate on a memory card (compact flash drive).

*1 Measurement method complies with Japan Testing Machinery Association (JTM). However, the calculation method is half the maximum value minus the minimum value when stable.

• This is the measured performance at the control point after stable operation for 30 minutes with an ambient temperature of +5 to +32°C and no load.
• The allowable voltage fluctuation is within ±5% of the rated voltage, and the allowable frequency fluctuation is within ±1% of the rated frequency.
• TVOC concentration of installation space (supply air) must be less than 300 μg/m³, and there must not be a significant fluctuation.
