Measurement System

The Gerdien Capacitor Method


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

Measurement range : Positive and Negative ion 0 to 5,000,000

R1= 0 to 8,000 ion/cc

R2= 0 to 50,000 ion/cc

R3= 0 to 500,000 ion/cc

R4= 0 to 5,000,000 ion/cc


1 piece/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.
