Portable odor detector for odor detection

Portable odor detector for odor detection

There is a smell all around us. In our daily life, we are surrounded by "smells" such as the smell of food, the odor of factory exhaust gas, and the fragrance of flowers and perfume. Moreover, the 'scent' generally does not stay in one place, but rather drifts away with the flow of air.

Humans are generally easy to smell(a kind of)'Smell', but in reality, this smell is formed by a mixture of various substances. Odorous substances mix with each other to form different "smells", some further enhance, some cancel each other out, and are almost imperceptible.

Function *, easy to useXP-329III can captureppbgrade(10one in a hundred million)The constantly changing 'scent' can“0000”～“20000”The digital digits and odor index display subtle changes that are difficult for human smell to perceive.

3： AboutXP-329IIIRExplanation of terminology for odor detectors:

odor

Odors include the "aroma" that represents fragrance and the "odor" that represents foul odor.

Here, "fragrance" and "odor" are collectively referred to as odors.

clean air

Clean air purified using activated carbon filters.

Zero position adjustment(Zero position setting)

Before measurement, inhale clean air and set the zero position as the measurement standard.

surveillance mode

Continuous and timely display of measurement values in measurement mode.

Normally, the peak value is displayed at the bottom of the measured value.

batch(BATCH)pattern

display1Measurement mode of minute peak value.

grade(LEVEL)display

To“0000”～“2000”The digital display shows the strength of the odor.

The so-called level value refers to the numerical value measured by displaying the level.

Odor index(INDEX)display

Convert the data measured by odor sensors using an odor index conversion table to obtain the odor index . To“00”～“40”Display the digital digits.

The definition of the so-called odor index in the odor prevention law is "the dilution factor multiplied by the dilution factor when using odorless air to dilute until no odor is felt10The numerical value. Specifically, the three-point comparative odor bag method is used, which is called the panel test subject sniffing the pre prepared odor bag3Select a bag containing an odor and slowly dilute it with odorless air until the bag containing the odor is no longer detectable. The dilution factor represents the concentration of the odor.

The dilution ratio is called odor concentration. Take the logarithm of the odor concentration and multiply it by10It's the odor index. The conversion formula is,

Odor index=10×10gOdor concentration.

The odor index of this machine(INDEX)Display the value of odor index equivalent to olfactory measurement method.
