Negative Air Ion Detector, Portable Negative Ion Concentration Meter
KEC-900A/KEC-990A/KEC-900M
一、Product features:
1, LED digital display value with continuous hold (HOLD) function, easy to take photos and interpretation;
2, standard with a mini tripod, fixed in the display place;
3, standard with an exquisite suitcase, portable and convenient;
4、The product is easy to use;
5, with the exclusion of electrostatic influence design, accurate test results;
6, good moisture resistance, suitable for high mountains, forests, waterfalls, caves and other high-temperature environment measurement;
7, AC and DC dual-use: can use 9V dry battery; can also use the socket power.
二、The function introduction:
- LCD display ( X 1000ION/CM ): displays the number of detected ions X 1000 = the actual number of detected ions.
- Hold the value (HOLD): LCD display of the number of continued to remain unchanged.
- Static shielding plate: Located in front of the air inlet (opposite to the operation panel), installing this static shielding plate and grounding wire at the same time can effectively reduce the impact of static electricity.
- Air inlet (visible to the internal measuring electrode plate): The air to be measured is sucked in here during measurement.
- Setting the sensitivity (SENS) for measurement: This can be changed depending on the measurement environment.
- Suction fan switch (FAN): Turn the switch up to ON and down to OFF.
- Zero adjustment knob (ZERO): Before the measurement starts, adjust the value to the “0” state.
- Grounding point (E): Connect the ground wire to this point to reduce the impact of static electricity.
- Power switch PWR, the switch is pulled to ON for on, pulled to OFF for off. Can use a 12VDC power adapter or a 9V battery power supply.

四、Usage:
1, before connecting to the power supply, make sure the suction fan (FAN) is off, choose to set the sensitivity of the measurement (SENS), and connect the ground wire to the ground.
2, access to the power supply (battery BAT or power cord DC), at this time the suction fan (FAN) continues to remain closed, at this time the LCD display figures from the big gradually decline, at this time do not touch the tester, until the figures almost no change. Adjust the zero (ZERO) button to the digital approximate zero.
3、Turn on the suction fan (FAN), then start the measurement.
4、If you want to adjust the sensitivity of the measurement (SENS), you must turn off the suction fan (FAN), and re-do the zero (ZERO) adjustment.
5、After the measurement is completed, the suction fan (FAN) and the power switch must be turned off. Please make sure the ground wire is grounded to maintain the accuracy of the measurement.
五、The scope of application:
Negative ion generator, air purifier, negative ion air conditioner, negative ion content of the measurement of health products; diatomaceous earth, negative ion wood flooring, negative ion wallpaper, and other decorative materials product testing; nano-coating room negative ion detection garden; forest system, forestry surveys, scenic spots, university laboratories, research institutes, and other ecological meteorological measurements and assessments.
