Benchtop pH Meter LBPM-B11

Benchtop pH Meter LBPM-B11


Benchtop pH meter LBPM-B11 is a tabletop meter with a pH range of -2.000 to 20.000 and 1 to 5 calibration points. Automatic temperature compensation provides accurate reading over entire pH range. Solution temperature coefficient compensates for the pure water samples. Relative and absolute modes provide reliable ORP measurements.
