Portable pH/ORP/mV Temperature Meter
50-HI991003 is protected
in a waterproof casing for use in humid and wet environments. It also features a
dual level LCD that displays pH or ORP and temperature (in degree C or F).
Automatic pH calibration can be performed with 5 memorized buffers (for NIST or
standard calibration). 50-HI991003 provides over 1500 hours of battery
life and an 8 minute auto-off period to save battery power.
With today's high level of
demand for quality and accuracy, it is critical, when measuring pH, to know the
status of the electrode, since it is the most important element of the pH
measurement system. An old, out of specifications pH electrode can result in
erroneous pH measurements that can seriously damage the process. The sensor check feature consists of a mV pH scale that shows the
characteristics (slope and offset) of the sensor, allowing the user to determine
if the electrode is in good condition. In several countries, local agencies
require pH electrodes to have slope % as high as 95%. This can only be done with
the sensor check feature.
50-HI991003 is supplied
complete with 50-HI1297D pH/ORP/temperature electrode, 3 x 1.5V AA
batteries, carrying case and instructions.
