ZAQ VOCs On-line Monitoring Sensor (ZAQ12V)
ZAQ12V (ZAQ12VG with GPS)
The ZAQ12V measures volatile organic compounds using a photoionization detector (PID), covering a range of 0-50 ppm with 1 ppb resolution. It also reports temperature and humidity, and is available with optional GPS as the ZAQ12VG. MetSensor UK supplies the ZAQ12V as the UK supplier of professional environmental monitoring sensors.

Frequently asked questions
How does the ZAQ12V measure VOCs?+
The ZAQ12V uses a photoionization detector (PID), which ionizes VOC molecules with UV light and measures the resulting current to determine concentration, over a range of 0-50 ppm with 1 ppb resolution.
Does the ZAQ12V measure anything besides VOCs?+
Yes. The ZAQ12V also reports temperature (-50 to 85°C) and humidity (0-100%) alongside VOCs.
Is GPS available on the VOCs sensor?+
Yes, the ZAQ12VG variant adds a built-in GPS module for location tagging of readings.
What industries use the ZAQ12V?+
It is used in Environmental Protection Department (EPD) style monitoring, industrial parks, factories, mines and urban pollution detection.
