I. Introduction
Formaldehyde (HCHO) is one of the most common, poisonous substances found in daily
life and industry. The HAL-HFX205 handheld Formaldehyde meter is a compact personal
monitor that can provide a rapid indication of hazardous airborne formaldehyde levels at the
touch of a button.
The HAL-HFX205, based on reliable electrochemical sensing technology, features directly
display of the formaldehyde concentration in ppm, and is easy to use. A short, low-
resistance diffusion pathway with a built-in pump enables a rapid reaction time.
Low power design allows long operation time. Exceptional linearity and stability allow easy
and very long intervals between calibration checks. The external digital temperature and
humidity sensors or pressure sensor, if applicable, allows compensation or correction for
accurate measurement. A USB port provides capability of downloading stored data and
possibly continuous, real-time monitoring of the environment remotely.
The HAL-HFX205 Formaldehyde Monitor is designed for use in a wide variety of
applications such asfurniture, floor boards, wall papers, paint,gardening, indoor decoration,
construction, dye stuffs, paper manufacture, hospitals, pharmaceutical, medical, food,
cleaning, synthetic resins, textile treatment, horticulture, and cosmetics.

II. Basic Operation
Six control keypads are used to operate the instrument: , RUN/STOP, ENTER, BACK,
, . Each button controls the following features:
•Power button : While the unit is off, press and hold the power button for
approximately 2 seconds to turn on the instrument. While the unit is on, press and
hold the power button for approximately 2 seconds to turn off the instrument. If the
instrument is not taking measurements it will automatically power off after 5 minutes
of inactivity.
•RUN/STOP: Start or stop measuring/sampling.
• : Move the cursor to select desired screen or item.
•ENTER: Confirm the current selection, enter a parameter, or save the current
sampling value.
•BACK: Change the concentration unit while the unit is measuring or return from the
current selection.
The side of the enclosure includes
•USB Interface: Connect the USB interface to a computer for data downloading or data
logging.
•POWER port: An AC adapter plug-in port: 5 VDC @ 1 A.
•Charge Status LED: LED flashes during charge cycle and becomes steady after the
charge cycle is finished.
