COM-3700高精度空气负离子监测器
COM-3700 　Air Ion Counter

Large ion counter
5.3800 ~ 0.00269 ｃ㎡／Ｖ・ｓｅｃ (2000 Steps Electric mobility)

Earthquake prediction air ion measuring instrument

The atmospheric ion counters of our company are the highly efficient products which use the "double cylinder pipe electrode" used by a scientific area of research.
The "double cylinder pipe electrode" is said for an electric field to have few turbulent flows of uniformity and air.

The positive ion and the negative ion which exist in natural environment can be measured by the highly efficient sensor of COM-3700.
Ion measurement of the various products which generate ion.Indoor ion distribution.In order to use it in various fields, such as ion measurement of natural environment, the personal computer output has.

The minimum range R1. 0-8,000 pieces/cc A wide range which can be measured without a range change.
R4 is the maximum range. 5 million pieces/cc
Setting change of electric mobility is possible.
The main part, data collection display software which can be used overseas.

Measurement system	The Gerdien capacitor method
Measurement	There are two kinds of measurement modes, automatic measurement and manual measurement, and it chooses according to a use and can measure. ■ Automatic measurement : A positive ion and negative ion are measured automatically and the display output of the measured value is carried out. ■ Manual measurement : A positive ion and an anion are measured individually and the display output of the measured value is carried out.
Time base range	Positive ion, Negative 0-5,000,000 1 piece/cc Measurement range : R1= 0 - 8,000 ion/cc　　 R2= 0 - 50,000 ion/cc R3= 0- 500,000 ion/cc　 R4= 0 - 5,000,000 ion/cc
Display for indication	Character 16-figure liquid crystal of two lines The display for indication of a STN system liquid crystal, and back light with an ON/OFF control facility
Clock function	The built-in clock which had a function of - part and a second at the time of year, moon, and day - is used.
Memory function	In order to carry out a memory, there are two kinds, automatic mode and a manual mode. 500 data can be saved. ■ Automatic memory : A memory is carried out with arbitrary time preset values. A preset value is 1, 2, 3, 4, 5, 10, 15, 20, 30, and 60 minutes. (It synchronizes with a built-in clock 5 minutes or more) ■ Manual memory : A memory is carried out to the arbitrary time under measurement by "MEMORY switch" setup.
Analog output	■ Analog output 1 (OUT1) : The measurement range under measurement, (0-1V) An analog recorder, a data recorder ■ Analog output 2 (OUT2) : The output range of R1, R2, R3, and R4 is set up. (0-1V) An analog recorder, a data recorder
Serial communication (RS-232C)	Data is outputted to external apparatus, such as a personal computer, in real time. It can be used for an external monitor etc. A set period is 1, 5, 10, 15, 20, 30, and 60 seconds.
Personal computer output	The data which carried out the memory can be outputted to a personal computer in the Excel form.
Printer output	Drawing of data and digital printing are performed to a thermal printer.
Electric mobility	5.3800 ~ 0.00269 ｃ㎡／Ｖ・ｓｅｃ (2000 Steps Electric mobility)
Power supply	DC12V ±10% (Power supply protection fuse 2A)
Temperature sensor	Time base range: 0 - 50 ℃ Accuracy: 1 ℃
Humidity Sensor	Time base range: 5% - 95% Accuracy: 5%
Ion measurement	5 ~ 35 ℃ 85%RH ≧ (Don't dew)
Main part	size: 130mm x 260mm x 340mm (A projection thing is not included) weight : About 7 kg
Detector	size: 160mm x140mm x 720mm (A projection thing is not included) weight : About 8 kg
