The APPA-365 is capable of simultaneously measuring three air pollutants (benzene, trichloroethylene, and tetrachloroethylene) generated through automotive and factory exhaust emissions that are known to pose a high risk to human health. Measurement is performed in 10-minute cycles, allowing the accurate detection of subtle density changes. In addition, its ease of operation and ability to produce stable measurements over the long term make the equipment well-suited to air-pollution monitoring.

The APPA-365 is capable of the automated, on-site, and simultaneous measurement of three air pollutants. The equipment automatically absorbs and measures a fixed amount of air sample, thus eliminating the need for extended sampling and troublesome preprocessing.

Because it fits into a 19-inch rack, the APPA-365 can be used to upgrade other HORIBA dry-type measurement equipment for air-pollution monitoring.

Automatic self-diagnostic functions and system-generated maintenance information enhance the ease of operation.
