ECFP21A1A1 pH Differential
Electrode and ECFR21A1A1 ORP Differential
Electrode
Unlike conventional combination
electrodes, the differential electrode
is designed for more durability in harsh
industrial environments such as wastewater
treatment. The unique electrode design
prevents fouling of the reference electrode
system. The salt bridge and reference
solution is replaceable hence providing
greater reliability, better accuracy and
a more cost effective measurement system.
Product Features
::
Extended electrode
life - Larger reference chamber filled
with buffer solution
minimises the effects of dilution and
prolongs electrode life.
::
Cost savings - The soiled
salt bridge and buffer reference solution
can be easily
replaced at a fraction of the cost of
a new combination electrode.
::
Automatic Temperature Compensation
- Built-in temperature sensor.
::
Up to 3000 feet signal transmission
- Built-in preamp eliminates high impedance
wiring problems hence signal transmission
is possible up to 3000 feet and hand
capacitance is prevented.
::
Minimised susceptibility
to ground loops - With differential pH/ORP
measurement technology.
::
Optimal mounting positions
- Compact design ensures less obstruction
when
used in pipe mountings and universal 1.5"
NPT mounting threads enables optimal
mounting positions.
