85LD Air Negative Ion Measuring Instrument Ion MeterAeroanion Detector Air Negative Ion Measuring Instrument Ion OOTDTY Air Negative Ion Measuring Instrument Ion Meter Aeroanion Detector Negative Oxygen Ions Anion Concentration Detector Auto Air Features: This negative ion can only measure some household appliances with negative ion , such as negative ion air , air conditioning fan, air conditioner, etc. which can release more than tens of thousands of high concentration negative oxygen ions. It can not test negative ions released from some ordinary natural environment and some solid ions. The is easy to carry and is suitable for testing high concentration ion sources such as various positive and negative ion s, air s and air conditioners. Measurement range: 10,000-19,990,000 (ion/cm³) Usage method: 1. Turn the switch to ON gear 2. Keep the thumb in contact with the square metal sheet of the front panel. The metal sheet on the ba faces the air negative ion to be tested. The closer the distance between the thumb and the air negative ion to be tested, the higher the degree of the , and vice versa, the smaller the degree of the . Therefore, in order to ensure the accuracy of the measurement results, please keep the at an appropriate distance from the air negative ion to be tested. 3.Do not-touch the square metal sheet on the ba of the with your hands during the measurement. Otherwise, the degree will be inaccurate. 4. There is no sign in front of the degree shown. Indicates that positive ions are measured; if "-" is displayed, negative ions are expreed. 5. Keep the hine switch in "off" position before each measurement. Specifications: Shell Material: Plastics Size: 80*30*10mm/3.15*1.18*0.39" Weight: 91g Notes: 1.
