●
pH : 0 to 14.00 pH, mV (ORP) : ± 1999 mV.
●
pH measurement can select
ATC or manual Temp. adj.
●
Optional ATC probe for pH measurement.
●
pH
measurement can make the auto calibration for pH 7, pH 4 and pH 10 or
other value.
●
Real time SD memory card Datalogger, it Built-in Clock and
Calendar, sampling time set from 1 sec to 8 hour 59 min. 59 sec.
●
Manual
datalogger is available (set the sampling time to 0), during execute the
manual datalogger function, it can set the different position (location) No.
(position 1 to position 99).
●
Innovation and easy operation, computer is
not need 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 the all the measured value 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.
