Conductivity, TDS, Salt, Temp., Data Logger
●
One meter for multi purpose operation: Conductivity, TDS (Total dissolved
solids), Salt measurement.
●
Conductivity : 200 uS/2 mS/20 mS/200 mS.
●
Salt : 0 to 12 % salt (% weight).
●
Conductivity measurement can select
Temp. Coefficient of measurement solution.
●
ATC for the conductivity
measurement.
●
Separate probe, easy for operation of different
measurement environment.
●
Real time SD memory card Datalogger,
built-in Clock and Calendar, sampling time can set from 1 sec to 8 hour 59
min. 59 sec.
●
Manual datalogger is available, during execute the manual
datalogger function, it can set the different location no. (position 1 to
position 99).
●
Innovation and easy operation, computer is not needed to
setup extra software, after execute datalogger, just take away the SD card
from the meter and plug in the SD card into the computer, it can down
load all the measured values with the time information (year/month/date/
hour/minute/second) to the Excel directly, then user can make the further
data or graphic analysis by themselves.
●
SD card capacity : 1 GB to 16
GB.
●
LCD with green light backlight, easy reading.
●
It can default auto
power off or manual power off.
●
Data hold, record max. and min.
reading.
●
Microcomputer circuit, high accuracy.
●
Power by UM3/AA (1.5
V) x 6 batteries or DC 9V adapter.
●
RS232/USB PC COMPUTER interface.
●
Wide applications:
water conditioning, aquariums, beverage, fish
hatcheries, food processing, photography, laboratory, paper industry,
plating industry, quality control, school & college, water conditioning.
