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

Measurement range : Positive and Negative ion are simultaneously 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

Resolution

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.
