AM319-Formaldehyde is a compact multi-sensor device that monitors an indoor environment for safety, air quality, comfort, and usage. It measures levels of formaldehyde and pollution in the air, as well as temperature, humidity, light, CO2 concentration, TVOC, barometric pressure, and motion. The E-ink screen shows real-time data, including overall assessment of the conditions of your environment. 

The nine sensors in AM319 can be configured to trigger text and email alerts whenever thresholds are exceeded. 

Why is formaldehyde monitoring important? 

Formaldehyde is one of the most used chemical compounds in the world. It is used in a variety of applications from healthcare and cosmetics to food additives, as well as resins used in wood processing and plastics manufacturing. However, Formaldehyde is a highly toxic substance when inhaled. It can cause severe irritation of the respiratory tract, skin and the eyes. Formaldehyde is considered a probable human carcinogen by the EPA - prolonged exposure to airborne Formaldehyde vapor may lead to lung and nasopharyngeal cancer. 

The AM319-Formaldehyde helps you monitor the level of TVOC, Formaldehyde and other pollutants ensuring the safety of your environment.
