New COM-3010PRO Portable Negative Anion Concentration Detector Solid Ion Meter Specification: Item: negative ion tester Dimension: W76xH140xD53 (mm) Weight: About 420g (battery excluded) Power: 4x UM3 alkaline dry battery (Not Included!) Consumption power: Approx. 100mW Measurement range: 0 to 100,000 (ions/cc, pcs/cm3) Detection accuracy: Approx. +/- 5% Minimum detectable (ion) density: 1 (pcs/cc) Display: LCD, 4+1/2digit Temperature Range: Measurement -10 ~ +50,When custody -20 ~ +60 Detectable ion: Negative air ions Detector effective area: 15.5cm2 (2.3 in2) Description: 1.The Ion tester is a high performance ion tester which is designed to measure anion (negative ion) generated by natural ores, and ceramics goods. 2. We recommend the best way to measure the measurement ten times, delete whichever is the average maximum and minimum values. 3.The sensor of tester is GM-Tube. It will count this signal to transform the amount of anion. For measure anion only, not for cation (positive ion) The Ion tester have 5 measurement modes 1. standard mode: The counter measures the average negative ions per 20 seconds. 2. High speed mode: The counter measures the average negative ions per 10 seconds. Good for fast measurement 3. Automatic measurement mode: The counter measures the average negative ions of 8 consecutive 20 second measurements. A thermal printer prints the maximum / minimum / average negative ion data if the 8 negative ions count. 4. Moving average mode: The counter measures the average of 16 negative ions counts collected during the first 20 seconds and those collected every second during the following 15 seconds. This mode provides more accurate negative ion count data. It takes 35 seconds to measure. 5. Radiation detection mode: The reading increases depending on the radiation dose the counter detects. The greater the dose, the faster the reading increases. Good for finding the source of the radiation. Measurement in progress: 1. Push the "POWER" button, and choose the mode to test; 2. Push the "START" button to start measurement. No reading is displayed and "---" moves from left to right on the display after 20 second for mode 1 measurement, and 10 second for mode 2 measurement, and 20 second for mode 3 measurement for once, total will display 8 times, then the average value; After 35 second will show the reading value for mode 4 and mode 5 will display real-time value. Remarks: when batteries gonna die, the display will show LOBAT, pls replace the batteries, so as not to affect the accuracy.
