Precautionary Statements
The following precautionary statements must be observed in order to use the unit safely and to
make the most of its functions:
WARNING
Avoid damaging or abusing the power cord. A short circuit may cause variations in
current, resulting in overheating and fire.
Make sure that the unit is grounded and that the plug is fully inserted into the power
supply. Ignoring this warning may cause overheating and fire.
Avoid inserting/disconnecting the plug into/from the power supply with wet hands.
Ignoring this warning may cause serious disaster due to electric shock.
Do not modify the unit in any way. It may cause an accident or a breakdown.
Do not insert the syringe for collecting oral gas samples deeply into the oral cavity.
Inserting the syringe deeply into the oral cavity may cause injury or respiratory
problems.
If you should recognize something unusual while using the machine, immediately stop
operation and contact the sales agent from whom you purchased this unit for inspection
and repair.
If the unit is used in a manner not specified in this manual, the unit’s protection may be
impaired.
CAUTION
Avoid installing, using, or storing the unit under the following conditions, which may
cause inaccurate measurements or damage of the unit, as well as significantly decrease
product life.
・Ambient temperature is outside the range of 10 to 30 °C.
・Ambient relative humidity is above 80%.
・Temperature and humidity change drastically and condensation occurs.
・Presence of odor or gas (including hydrogen, methane, odor of alcohol, formalin
and other chemicals, cigarettes, or aromatic oils, etc.)
・Vibration or impact directly affects the unit.
・Exposure to water, oil, chemical, or steam.
・Presence of dirt or dust.
・There is a serious induction problem where static electricity, magnetism, and noise
tend to be generated.
・Exposure to direct sunlight.
・The airflow from an air conditioner blows directly on the unit.
・Rooms in which gas- or kerosene-fired heaters are used without ventilation to the
outside

3
・Places where gas tends to accumulate, such as a low position near a floor.
This is a single-purpose oral breath-measuring unit. Never inject any material other than
breath samples (E.g., liquid substances including chemicals, water, and saliva, or any
kind of gas). Ignoring this warning may cause mechanical failure or performance
degradation.
To obtain a stable measurement result, leave the power on during office hours. If you
have not powered on the machine for more than one week, the measured value may be
lower than the actual value immediately after power on due to the characteristics of the
sensor.
If you are not using the unit for a long period of time, disconnect the plug from the power
supply. Ignoring this warning may cause fire.
Do not wipe the surface with benzine, thinner, alcohol, etc. Use a clean, dry cloth when
cleaning. Ignoring this warning may cause inaccurate measurements, degradation of the
unit, or fire.
Do not wipe the syringe by rubbing it with alcohol. Do not touch the syringe with a bare
or gloved hand that has been exposed to an antiseptic solution.
Use only designated syringes.
Allow ten minutes before measuring if the subject has used a product containing
alcohol, such as mouthwash or toothpaste. It may affect the measurement results, or
influence measurement value.
Do not place anything on the machine. Ignoring this warning may cause overheating or
damage.
Do not disassemble the unit. We do not guarantee the accuracy of data or operation of
the unit if the unit has been disassembled.

Overview
The OralChroma measures and classifies volatile sulfur compounds in human breath samples
into three causal components (hydrogen sulfide, methyl mercaptan, and dimethyl sulfide), then
displays each gas concentration on your PC. It is easy to use and requires only four minutes to
analyze the sample. It provides more opportunities for people to check their oral breath.
■ Features
・Measures volatile sulfur compounds in the oral breath sample; classifies the sample
into three causal components of halitosis: hydrogen sulfide, methyl mercaptan, and
dimethyl sulfide; and displays each gas concentration on your PC in units of ng/10 ml
and ppb.
・Measures gas concentrations with a high degree of accuracy by using a supersensitive
semiconductor gas sensor and a column developed only for the purpose of detecting
halitosis.
・Does not require a carrier gas cylinder although the gas chromatograph method has
been adopted. Thus, the unit can be considered portable. It is very easy to operate and
does not require any specialized knowledge. Just connect it to the power supply and
use immediately.
・Requires only 4 minutes to measure the concentration of all three components.
・Small and light, the OralChroma is easy to carry.
・Real-time graphical representation of the measured data is produced by connecting the
machine with a PC and using specially designed software.

5
■ Mechanism of measurement
The following constitutes the procedure for measuring oral breath concentrations:
1. Collect oral breath samples and inject the specified volume of gas into the column.
2. Separate volatile sulfur compounds from the gas by using the column and detect the
gases with the semiconductor gas sensor.
3. Calculate gas concentrations from the peak patterns obtained.
