The IT-10 measures the concentration of negative ions in air and displays results in pieces per cubic centimeter (Pcs/cm³).
Measurement range is 0–99,990 Pcs/cm³ with a resolving power of 1 Pcs/cm³. Values above 9,999 are displayed using X10 magnification.
The stated measurement accuracy is less than ±15% under normal operating conditions.
The IT-10 provides Quick Measurement, Standard Measurement, and Accurate Measurement modes. Quick is for fast checks, Standard for routine monitoring, and Accurate for more stable/precise readings (longer averaging).
Results appear on a 4-digit LCD display. The device can store up to 28 recent test data entries for review and comparison.
The tester is powered by a universal 9V dry battery, making it portable and suitable for field use.
Operating temperature range is -20°C to 60°C and humidity range is 5%–95% RH, allowing use in a wide variety of environments.
Dimensions are 151 × 80 × 36 mm and the weight is approximately 0.35 kg, so it is compact and lightweight for carrying.
The IT-10 uses a high-performance GM (gm) ion detector as its measurement principle to detect negative ions.
Yes, the device is CE certified (EMC1674), indicating compliance with relevant safety and electromagnetic compatibility standards.
Yes. The IT-10 is suitable for evaluating negative ion concentrations produced by ionizers, air purifiers, and similar devices, as well as in rooms and public spaces.
No. The ONETEST IT-10 is designed specifically to measure negative ion concentrations.
Yes. The tester automatically shuts down after 15 minutes of no operation to conserve battery power.
Keep the unit dry and avoid exposure to extreme conditions beyond the specified ranges. For calibration or service procedures, refer to the user manual or contact the manufacturer or authorized service center for recommended calibration intervals and instructions.
Allow the device a short stabilization time after power-on, ensure you are within the specified operating temperature and humidity, and verify battery condition. If problems persist, consult the user manual or contact customer support for troubleshooting and possible recalibration.
