Selective Measurements

The Model PHB-357 microprocessor­based, benchtop meter brings very
accurate pH and mV measurements to the
laboratory. Useful design features include
automatic buffer recognition, automatic
calibration, recorder output for permanent
recordkeeping, splashproof keypad to
prevent damage from spills, display hold
function and 9V battery memory back­up. With 0.1 mV resolution, this versatile
instrument can also perform ion selective
measurements. It operates on either
115 Vac line power or a 9V battery.
Supplied with the PHB-357 meter
is an epoxy-bodied general purpose
pH electrode, a temperature
probe and an AC power adaptor.

smaller than actual size.

pH electrode and
temperature probe included.
