Zowaysoon Mini Air Ion Checker Meter Counter Negative Anion Concentration Detector Tester

Safety: The instrument is equipped with a ground wire 1M ohm
Power-saving mode: 5 minutes of inactivity, the instrument automatically shut down
Positive and negative display:When measured by positive ions, show positive data, when measured ions, after data showed the negative sign "-";
Operating voltage: 2X3V
Battery: CR2032 button batteries use two
Portable: Size is 120mm (length) x 45mm (width) x20mm (H)
<10000ions/cm, The direct display of data and units;
≥10000 ions/cmTime,The data rate, combined with the display unit;

ON / OFF: switch button, tap the key once boot; press again, off;
HOLD: Solutions for the lock button, after reading lock or need to re-test, press the switch again to unlock the re-test
Press the ON / OFF button to boot, so tester back metal plate align the measured ion source, its distance according to testing requirements may be, you can read the tester reading is stable until the lock was local ion concentration
maximum time, unless there are ion concentration is greater than readings appear, or press the unlock button reading is updated.
negative ion generator when testing a type of air purification products, according to industry rules generally should be 30 cm away from the ion source to measure the maximum reading as the ion concentration of the ion generator.
Contact with the front small metal plate with your fingers while rough measurement, accurate measurement of the front should be kept small metal plate in contact with the grounding device with this instrument, not touch the back of a large metal plate ion accepted. Measurement should avoid other high voltage electric field ion source or class objects, in order to avoid errors.
