Dependably measure volatile organic compounds with the TVOC sensor. With the deployment of a fixed continuous monitor, users can avoid dangers by monitoring areas in question. A variety of industries use the TVOC to minimize poisoning and explosions. 

Requires analog port selection during U30 system configuration and use of a S-FS-CVIA when using the H22-001 data logger. When using a U12 data logger or ZW series data loggers, this sensor requires a 4-20mA input cable (CABLE-4-20mA) and external power provided by an AC adapter (AC-SENS-1).
