Price and availability on request

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.
LCD with green light backlight, easy reading.
Can default auto power off or manual power off.
Data hold, record max. and min. reading.
