Proccess pH/ORP Electrodes

Totally Nonglass pH Electrodes for Fluoride solutions

Before you buy another glass pH electrode
consider these advantages

*Useable in all Fluoride solutions.  Use this totally
 nonglass pH probe in acid pickling baths, chromium
 plating baths, aluminum polishing baths, and any other
 bath which contains fluoride and does not permit the
 use of glass pH electrodes.

*Unbreakable.  An added advantage of this solid state
 probe is that it is unbreakable, saving you money in
 replacement costs.

*Use with All Standard pH/millivolt meters or monitors.
 The nonglass pH probe can be used directly with all
 standard pH/millivolt meters.  The probe plugs directly
 into the meter.

*Bath and laboratory size Electrodes Available.  The
 nonglass pH probe comes in two industrial sizes for
 dipping directly into your bath or laboratory size for
 beakers.

INLINE pH/ORP ELECTRODES FOR INSTALLATION IN A PIPE TEE

The inline electrodes are designed for mounting on standard
1/2" or 3/4" pipe tees for continuous pH or ORP flow-thru
monitoring.  They are constructed with a sealed gel-filled
reference which requires no pressurization or refilling
during use.   The electrode reference junction features our
standard annular ceramic junction which permits use where
high-solution currents prevail and is unaffected by
streaming potentials.  With the large reference surface
area, reference clogging is not a problem.  Order GX3 glass
for high pH measurements where high concentrations of sodium
are present.  The double junction is used for samples
containing organic compounds, proteins, heavy metals, or
other compounds which inter-react with silver.  For ease of
installation detachable leads are available.

 Submersible Electrodes 

DISPOSABLE LOW MAINTENANCE SUBMERSIBLE ELECTRODES

This series of electrodes is designed for ease of
maintenance and electrode replacement.  They are designed to
be submerged into a tank or trough for waste water or
industrial use where continuous pH or ORP monitoring is
required.

The combination electrode is encapsulated in a 1" O.D. by 3
ft. ABS pipe, eliminating electrode replacement in the
housing and resultant seal leakage.

The sealed, gel-filled reference requires no pressurization.
The annular reference junction is of special design,
allowing operation in processes that would normally foul a
standard combination electrode reference.

A wide variety of electrode types is available:
1. pH, ORP (platinum or gold) electrodes.
2. Single or double junction references.
3. Low sodium ion error electrodes.
4. Antimony pH electrodes.

The electrode assembly reduces maintenance cost due to the
ease of electrode handling and replacement.  Electrodes
compatible with nearly all pH and ORP instrumentation are
available.  They may be ordered with an optional integral
temperature compensator.  Refer to Temperature Compensator
Selection Sheet, Bulletin 1187.

Optional construction of CPVC or Kynar is available.  Longer
pipe length is also available.
