Product Description

Featrues: Test Range: 1000--9999104ions/ cm Simple: two buttons to complete all testing operations Operating voltage: 2X3V Battery: CR2032 button batteries use two(not included) Portable: Size is 120mm (length) x 45mm (width) x20mm (H) Operation: 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. As the air ions have instantaneous, multiple factors affect the air flow, environmental disturbance, wind direction, temperature and humidity, sound and vibration that, when making the ambient air ion concentration measurement, instantaneous value, the average of multiple measurements taken as a reflection of generous environmental conditions ion concentration. When measuring the negative ion generator products, can not interfere in the test chamber by describes several methods for measuring taking the mean value as a product index.
