AlphaLab รุ่น IC-1000-W เครื่องวัดปริมาณการปล่อยประจุไอออนบวกและลบ,Air Ion Counter meter of positive and negative ion,Meas.range:100～19,990,000(pcs/cc)

Detectable ion

Positive/Negative small air ions

Air flow rate

400 (cm³/sec)

Efficiency of ion collection

65%

Input resistance:

10¹⁰ Ohms

Battery

One 9V alkaline. Current drain is about 5mA on STANDBY, and 40mA on MEASURE. All 3 decimal points display when battery becomes weak (below 7.4V). Battery life is about 40 hours on STANDBY and 2-3 hours on MEASURE.

Measurement range

100 - 19,990,000 (pcs/cc)

Range 199.9T: 100 - 199,900 (pcs/cc)
Range 1.999M: 100,000 - 1,999,000 (pcs/cc)
Range 19.99M: 100,000 - 19,990,000 (pcs/cc)

Measurement method

Parallel flat plates method

Mobility

0.8 (cm²/Vs)

Noise level

(2 second-weighting) approximately 10 ions/cm³

Accuracy

+/-25% for fast ions (mobility greater than 0.8 (cm²/VS) - these are the most numerous ions. This ion counter is less sensitive to "slow" ions such as charged pieces of dust).

Minimum detectable density

100 (pcs/cc)

Setting time

approx. 2 seconds (response time), and 10 sec (after switchover between "+" and "-")

Ion Selectivity (crosstalk)

1:5000. That is, if POLARITY is set to "+", the meter will display 1/5000 of the "-" ion density (as a negative number) if there are many negative ions and no positive ions. With POLARITY set in its center position, the meter will read a number which is 1/10 the "+" density, minus 1/10 the "-" density.

Operating temperature range

0-50C (14-122F)

Operating humidity range

90% R.H. or below (no condensation)

Weight

approx. 460g

Dimensions

W90xH160xD58 (mm)
