Advanced Features:
Large LCD with Multiple Display
Display of pH, temperature and time simultaneously
Autolock Measurement
Meter automatically sense a stabilized endpoint reading
This ensures workers only takes in an accurate reading
all the time and every time.
Multi-point calibration
Automatic buffer recognition with built in standards:
ISO - pH7.00, 4.01, 10.01
NIST - pH6.68, 4.01, 9.18
Custom - Manual set to any buffer standard.
Up to 5 points calibration
Electrode status indicator
Able to display percentage of slope of the electrode after successive calibration. This feature enables user
to determine if the electrode should be replaced due to wear and tear.
Real Time Memory
Able to save records of up to 99 data memory with date and time, enable download to PC.
Online PC link
Able to link to a PC for online display with optional PC kit (sold separately) and download saved data.
Meter uses regular AAA size batteries and tap power source from PC when connected via the USB cable.
