Formaldahyde and TVOC Meter - (FM260)
The Triplett Model FM260 Formaldehyde and TVOC Meter can simultaneously display real-time measurements of HCHO/CH2O (Formaldehyde) and TVOC (Total Volatile Organic Compounds) concentrations in the air. Read More > 
DESCRIPTION
The Triplett Model FM260 Formaldehyde and TVOC Meter can simultaneously display real-time measurements of HCHO/CH2O (Formaldehyde) and TVOC (Total Volatile Organic Compounds) concentrations in the air. Potential sources for TVOCs include paints, finishes, adhesives, cigarette smoke, pesticides, personal care products, car exhaust, new furnishings, wall coverings, household cleansers, and cooking fuels. Chemicals include: Acetone, Ethylene Glycol, Formaldehyde, Xylene, 1,3‐butadiene, Tetrachloroethene, Hydrogen Sulfide, Ammonia, Toluene, Benzene, Methylene Chloride, Perchloroethylene, and MTBE. The meter features Fuel Cell Formaldehyde Sensor Technology for high accuracy measurement, a backlit dual LCD, two selectable units of measure (ppm, mg/m³), audible and visual high/low alarms for HCHO. Auto power off conserves battery life. Includes rechargeable 7.4V Li-Po battery and AC charger/adapter. 1-year warranty.

Q. Is my Triplett FM260 Formaldahyde and TVOC meter calibrated?
A.If you wanted to periodically check to make sure the unit is accurate yourself, you would invest in some formaldehyde reference calibration gases. The range of this meter is 0.00 to 5.00 mg/m³ (or PPM) so you would want to find a gas in this range and then you’d have to set up some sort of chamber or stable temp, humidity, and pressure environment. The less expensive option may be to find a calibration lab that offers this type of service and see if they can verify it and provide you with a NIST certificate.
Here is some online information that may help you - GASCO Formaldehyde Calibration Test Gas (calgasdirect.com)
If you are looking for what a “good, bad” reading should be – I would suggest you look at the latest OSHA standard guidelines here for this type of info as they are always changing and depends on environments – closed/open etc.,

Q. What sensors FM260 uses. Are they MOS sensors or electrochemical sensors? Does it use two different sensors for Formaldehyde and the mixture (TVOC), respectively?
A.The FM260 utilizes a fuel cell type sensor. It uses the same type sensor for both TVOC and HCHO.
-
Q. What calibration comes with the FM260 and do I require a standard gas calibration?
A.The FM260 is calibrated to the standards specified in the user manual before it leaves the factory. The unit should arrive to you ready to use (unless the battery requires charging).
