CAUTIONS
●Do not install, use, or store the unit at a place where:
- Ambient temperature is not in the range of -10 to 40℃. (14-104°F)
- Ambient humidity exceeds 90% R.H.
- Condensation occurs due to rapid temperature change.
- Corrosive and/or explosive gases exists.
- Direct vibration and/or steam occurs.
- Mush dust, salty materials, and/or iron powders exist.
- Static electrons, magnetic, and/or electronic noise can occur.
- Cool or warm air from conditioners has direct influence.
- The unit is exposed to direct sunlight.
- Heating occurs due to heat radiation.
●Do not turn off the power during detection.
●Do not remove the
button battery besides exchanging the battery is
needed. It causes loss of the the internal memory data and initializes
Date and Time.
- Exchange new batteries if battery status displays “Low.”
- Remember to transfer the the internal memory data to your PC before taking
out the battery.
- Taking out the battery causes loss of the internal memory data
. Check if no
necessary data is in the memory.
●Store the sensor assy at cool and dark place (below 25°C/77°F) in
the
sealed state aluminum bag before and after opening.
●
Accustom the sensor assy at ambient temperature before opening the
aluminum bag.

2．General Description
FMM-MD consists of portable base unit and detachable formaldehyde sensor assy.
The sensor assy can be used as stand-alone passive sampler and also can be used
in combination with base unit.
The sensor assy can be used repeatedly up to the usage limit.
Base unit reads absorbance change induced in the sensor before and after the each
measurement respectively and converted result into formaldehyde concentration.
Measurement can be done in multiple modes as follows;
1. Direct Measurement mode（Use base unit with sensor assy inserted.）
Base unit in combination with the sensor works for normal Direct Measurement for
duration of 30 min or 1 hour.
2. Samplers Measurement mode （Use sensor assy alone as passive sampler
and base unit reads out measurement result.）
Sensor itself can work as stand-alone passive sampler. No fan, nor pump necessary.
Use base unit to read the relative absorbance change induced in the sensor before
and after the sampling and covert that into formaldehyde concentration.
3. Continuous Measurement mode（Use base unit with sensor assy inserted.）
Base unit reads the absorbance change every 30 min and store the data sequentially.
All the measurement results can be viewed on LCD panel, and also filed into PC with
using Data filing software.

2-3-1Description
・Use the sensor assy till the date shown on the sealed bag.
・ The sensor assy is sealed with the diffusion filter capped.
・Store the sensor assy with the diffusion filter attached at cool and dark place(below
25℃/77°F) in the sealed state aluminum bag before and after opening.
・Accustom the sensor assy at ambient temperature before open the aluminum bag.
・For reliable measurement result, the sensor is designed to secure its primarily
performance by going through the prior exposure to measurement environment for
60 min, before the actual measurement.
・Be sure to attach diffusion filter to the sensor assy for Samplers Measurement,
unless reliable measurement cannot be detected.
・The sensor assy can be used repeatedly up to the usage limit.
・Use fresh (new) sensor assy to avoid unintended interruption of measurement,
when you plan for long-term measurement and/or expect high concentration
measurement such as ≧200ppb or so.

will apply to the

●
In case the sensor reaches the saturation point, measurement is
automatically stopped. LED light indicates when this occurs.

measurement, when you plan for long-
term measurement and/or expect
high concentration measurement such as ≧200ppb or so.
