Formaldehyde—which is colorless and has a characteristic pungent, irritating odor—is ubiquitous. It is produced by the oxidation or combustion of methane and other carbon compounds and is therefore present in forest fires, automobile exhaust, and tobacco smoke. When produced in the atmosphere by the action of sunlight and oxygen on atmospheric methane and other hydrocarbons, formaldehyde becomes part of smog.

hardeners and nail polish, and as the wet-strength material added to sanitary paper products such as facial tissue, table napkins and roll towels. Production of formaldehyde resins accounts for more than half of formaldehyde consumption. Other formaldehyde derivatives include methylene diphenyl diisocyanate, an important ingredient of polyurethane paints and foams.

levels, starting at around 1.9 ppm, has been shown to result in significant damage to pulmonary function, resulting in reduced maximum mid-expiratory flow and forced vital capacity. There is also research that supports the theory that formaldehyde exposure contributes to reproductive problems in women. RESIDENTIAL EXPOSURE In the residential environment, formaldehyde exposure comes from a number of different routes;...

0.3 ppm. In controlled chamber studies, individuals begin to sense eye irritation at about 0.5 ppm; 5 to 20% report eye irritation at 0.5 to 1 ppm; and greater certainty for sensory irritation occurred at 1 ppm and above. While some agencies have used a level as low as 0.1 ppm as a threshold for irritation, the expert panel found that a level of 0.3 ppm would protect against nearly all irritation.

WHAT’S IN THE PACKAGE The FD08, a 110VAC adaptor and this user’s manual come in a soft pouch inside a white box. PRODUCT OVERVIEW Fig. 1 shows all controls, indicators and physical structures of the FD08. Fig. 2 shows all possible indications on the LCD.
5. Threaded tripod mounting screw hole (on bottom) 6. Jack for AC adaptor (on side) Fig. 2. All possible display indications SETUP INSTRUCTIONS INSTALL BATTERIES The FD08’s battery compartment (Fig. 1, Callout 4) is located on the lower back of the meter.
OPERATING INSTRUCTIONS To power on the FD08, briefly press the PWR button. The LCD will illuminate and immediately begin scrolling “0s” across the five positions on the upper readout to indicate that it is warming up.

2) Calibrate the meter to 0 ppm. With the FD08 powered on in a room completely free of formaldehyde gas, enter calibration mode by pressing and holding the MODE button.

4) Change the unit of the ambient temperature value shown on the lower readout to/from °F and °C by pressing the UNIT button. The FD08 will “remember” the unit in use when the meter powers off and will resume using that unit when it is powered on again.

RH at multiple locations. The session begins when you power on the FD08; it typically ends 15 minutes after you finish making measurements with the activation of the APO function. You can extend a measurement session beyond...
15 minutes by pressing any front-panel button (in effect, resetting the clock to zero) or by disabling the APO function and powering the FD08 through the optional AC adaptor (see page 11 to learn how to do this). The value of being able to quickly determine where the level of formaldehyde is highest and lowest in an area or facility should be obvious.
FD08 powered long enough to calculate and display the three cumulative formaldehyde exposure metrics. Remove the batteries if you don’t expect to use the FD08 for an extended period of time (months or years). The meter uses a capacitive RH sensor and a thermistor...

Blow off loose particles with compressed air. Gently brush remaining debris away with a lens hair brush. Never use a solvent or an abrasive cleaner on the FD08. To clean the housing, use a soft, damp cloth. Do not drop or disassemble the meter or immerse it in water.
