Simple 1, 2, or 3 point calibration
Large, high contrast, LCD display; displays pH/mV and temperature simultaneously
AUTOLOCK mode holds stable measurements on the display
Accepts U.S. (7.00, 4.01, 10.01) or NIST (6.86, 4.00, 9.18) buffer sets
Automatic/manual temperature compensation*
Automatic lock mode and end point sensing feature will lock in stable measurements
BNC input allows for any pH or ORP electrode with BNC to be connected*
