Overview

      The negative ion test equipment for the air negative ion generator to measure the negative ions and positive ions generated by the concentration of the design. The use of this machine, you can determine the air anion generator or air purifier negative ions produced by the polarity is correct, and roughly estimate the concentration of ions generated by the measurement. If after calibration, can make the tester reading under certain conditions and standard air ion concentration meter reading close to.2, functional characteristics

2.1 The tester is suitable for a variety of positive and negative ion generator, air purifier, air conditioner and other high concentration ion source for testing. Measuring range: 10,000 ~ 1999 (ion / cm3)

2.2 The tester easy to carry, nice. Can carry, can be used as decorations and gift gifts.

2.3 Power: 1.5vx2 LR44 battery3 use method

3.1 Turn the switch to "ON" position

3.2 keep the thumb in contact with the square metal plate on the front panel, the back of the metal plate toward the negative ion generator to be detected, and the closer to the negative ion generator to be measured, the higher the degree of the tester, and vice versa small. Therefore, in order to ensure the accuracy of the measurement results, please keep the tester at the proper distance from the negative ion generator to be tested.

3.3 During the measurement, do not touch the back of the tester square metal sheet. Otherwise it will make the degree inaccurate.

3.4 If there is no sign in front of the displayed degree Said that measured positive ions; if "-", then expressed as negative ions.

3.5 Hold the machine switch in the "off" position before each measurement.4 matters needing attention

4.1 The tester is a high impedance tester, the use and collection process to prevent moisture, if the moisture will cause the test instability, the degree of the problem of confusion. At this point you can use the hair dryer to dry and restore. Can also be placed in the sun for a few hours.

4.2 When the machine runs out of battery, it will display low voltage symbol, then open the back cover, replace the same type of battery, replace the battery should pay attention to the polarity of the battery.

4.3 If you need a more accurate number of ions or the ion content of the environment under test 10,000 (ion / cm) below, please choose other negative ion detector.
