Brand: Kalmor
Brand : POLFA
Product Features:
Graph display
POLFA indicates measurement result instantly on display. It is easy to understand that odor intensity changes.
High Sensitivity
POLFA adopted Metal oxide semiconductor gas sensor which are higher sensitivity than conventional Odor measuring instrument of Karumoa.
Working Principle
The oxygen in the air absorbs the electrons on the sensor surface when it is heated at high temperature. It becomes a resistance of electrical flow in the sensor element. If an odor component with a reducing potential comes to the sensor under this condition, the electrons in the sensor can move freely and the electricity can flow highly. This product reads this voltage difference and displays the odor intensity as the measured value calculated by our original formula.
Why I need Polfa ?
1) I want to measure the odor level inside the factory and around the boundaries of the site.
2) I want to use it for daily odor measurement work for environmental management and odor management.
3) I want to measure the effectiveness of deodorizing equipment.
4) I want to use it to measure indoor odors and manage the presence or absence of odors.
5) I want to see the effects before and after deodorizing measures/work, etc.
6) I want to measure odor and control quality when receiving and shipping products.
7) I want to measure bad breath and body odor
Various Functions of POLFA
Do not need other app DATE COLLECT
POLFA is equipped with date collect function mode. It is possibility that you measure long hours at 1 second, 1 minutes, 30 minutes and so on intervals. Date format is CSV files and this is recorded to micro SD card, so you do not need install any application.
Record atmospheric temperature / humidity SIMPLE THERMO/HYGROMETER
POLFA is equipped simple thermometer and hygrometer to support measurement. POLFA is affected from temperature and humidity. After measurement, use the measured value as reference.
Change a measuring range SCALE CHANGE
When odor is weak, you use this function. This function makes the difference big, so you can measure a slight difference.
Make a graph of odor fluctuations GRAPH DISPLAY
A graph is a real-time measured value, which is plotted every 2 seconds. you can see odor fluctuations conveniently.
Possible to adjust zero point ZERO POINT CALIBRATION
Usually you do not need calibration but you can get a temporary zero point calibration value when sensor material deteriorate or you need.
Long hour working outside AA-SIZED BATTERY
Power saving design, up to 16 hours operation available with four AA dry cell batteries. Compared to rechargeable batteries, it’ s easy to bring spare power supply, and convenient in the field. ※ Up to 8 hours operation with the condition of display light always on.
Indicate max value PEAK-HOLD FUNCTION
It is possible to indicate max value during peak-hold. If you miss a measured value, it is ok.
Bilingual ENGLISH LANGUAGE MENU
MENU is written in simple English for every users. Anyone can use this.
