COM-3700PRO Specification

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.
