Thank you for purchasing OMEGA’s HHAQ-108 Formaldehyde Meter. Please read this user’s manual carefully and thoroughly before using the product. The HHAQ-108 is an easy-to-use handheld instrument for measuring levels of gaseous formaldehyde (HCHO) as part of a workplace indoor air quality (IAQ) maintenance program or to spot-check a residential environment. - Page 5 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.
- Page 6 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.
- Page 7 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;...

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.

Page 12: Operating Instructions
OPERATING INSTRUCTIONS To power on the HHAQ-108, briefly press the PWR button. The CD will illuminate and immediately begin scrolling “Os” across the five positions on the upper readout to indicate that it is warming up. - Page 13 2) Calibrate the meter to 0 ppm. With the HHAQ-108 powered on in a room completely free of formaldehyde gas, enter calibration mode by pressing and holding the MODE button.
- Page 14 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 HHAQ-108 will “remember” the unit in use when the meter powers off and will resume using that unit when it is powered on again.

15 minutes by pressing any front-panel button (in effect, resetting the clock to zero) or by disabling the APO function and powering the HHAQ-108 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. -

HHAQ-108 powered long enough to calculate and display the three cumulative formaldehyde exposure metrics. Remove the batteries if you don’t expect to use the HHAQ-108 for an extended period of time (months or years). The meter uses a capacitive RH sensor and a thermistor... - Page 18 HHAQ-108’s temperature and/or RH drift. Following is a procedure that you can perform to offset either or both types of drift and thereby restore the HHAQ-108’s specified accuracy. 1) With the meter powered off, press and hold the MODE and...
- Page 19 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. There are two error messages you may encounter when using the HHAQ-108:...
- Page 20 Er1: Typically indicates damage to the formaldehyde sensor, ambient temperature sensor or RH sensor. Er2: Typically displayed for 1 second on the lower readout when the meter tries to measure a temperature or RH value outside the specified measurement range. It may also be produced by clearing the Max/Min memory.
