Extech VFM200 VOC/Formaldehyde Meter
Extech VFM200 gives fast and clear air checks for formaldehyde and VOC levels. It is made for indoor air work, and it helps users see changes in air quality in real time.
Readings for HCHO and TVOC appear at the same time on the backlit screen. As a result, users can check both values at once and act quickly when levels rise.
Clear Readings for Daily Air Checks
This handheld meter uses professional fuel cell technology for steady sensing. It also shows results in mg/m³ or PPM, which makes the Extech VFM200 easy to use in different test needs.
Response time is less than two seconds, so the unit reacts quickly to changing air conditions. In turn, this helps users check rooms, work areas, and enclosed spaces with less delay.
Portable Design for Practical Use
High and low alarms can be set by the user for simple warning control. Because of this, Extech VFM200 can give a clear alert when the reading moves outside the chosen limit.
A rechargeable lithium-ion battery supports portable use, while auto power-off helps save charge between checks. The battery reaches full charge in about three hours with the supplied AC charger and plug set.
Its compact body is light enough for regular field use and easy storage. The backlit LCD stays simple to read, and the carry pouch helps protect the meter when moving between jobs.
Extech VFM200 suits industrial sites, indoor air checks, and general environmental monitoring. It comes with the main items needed to get started, and it is backed by a 1-year manufacturer’s warranty.
