Description: The Metravi ET-99HT HCHO and TVOC Meter is an instrument for real-time measurement of HCHO (Formaldehyde) and TVOC (Total Volatile Organic Compounds) in the surrounding air.
The formaldehyde sensor adopts an electrochemical sensor with high-precision and fast response. TVOC measurements are done using a semiconductor sensor, which needs preheating when working. The values of TVOC and formaldehyde can be switched between PPM and mg/m3 units by pressing a key. This instrument also has the functions of MAX and MIN measurement modes and HOLD mode. In addition, it also has an automatic shutdown function that can be disabled, if need be, along with the backlight off and on function and the low power prompt function. |
