||PINPOINT™ ORP Monitor
American Marine is proud to introduce PINPOINT REDOX/ORP
Monitor™, the only truly accurate and affordable continuous
monitoring ORP (REDOX) system. Every PINPOINT REDOX/ORP
Electrode features a 10-foot high suppression cable, BNC Connector
as well as a 99.9% platinum sensor tip. A PINPOINT AC Adapter
Kit is recommended since ORP values are most important when
continuously monitored. Standard 9-volt battery can be used and should be
replaced every few months when visually indicated on the display as
NOTE: The REDOX/ORP Monitor
unit is NOT waterproof and must be operated on a dry surface. Liquid
contact on the printed circuit board will cause corrosion and void
protective plastic packaging from the PINPOINT REDOX/ORP Monitor unit.
Remove the battery cover on the back of the monitor and install a new
9-volt battery or the PINPOINT AC Adapter Kit. Use the pop-up stand on
back and place meter on a flat, dry surface. Velcro can be used to mount
the meter onto a vertical surface. Carefully remove the plastic storage
container installed on the end of the electrode. A small amount of storage
fluid may be expelled this is normal. SAVE the plastic storage container
for future use. Rinse the end of the electrode briefly under lukewarm
water. Place the electrode tip into the fluid to be measured using the
suction cup probe holder if desired. Attach the BNC Connector from the
electrode onto the BNC input of the ORP Monitor. Turn the connector ¼ turn
clockwise to lock the connector. Activate the unit by setting the power
switch to the ON position. Your PINPOINT
REDOX/ORP Monitor is now ready for calibration.
As with any
lab quality REDOX/ORP Electrode it is important to wait the full 24–36
hours before recording ORP values when continuously monitoring. During
this period the electrode should "settle in" to the new
The PINPOINT REDOX/ORP Electrode is widely considered
to be a superior grade and should be precisely calibrated to the PINPOINT ORP/REDOX
Meter before initial installation. Place the tip of the REDOX/ORP
Electrode into the REDOX 400 Calibration Fluid and wait a minute or so for
the measurement to settle in. Adjust the calibration screw on the front of
the monitor to read 400mV. Calibration should be checked monthly for
maximum precision. Do not reuse the calibration fluid.
electrode occasionally (every 3–4 weeks) using a wet soft toothbrush with
long bristles. Gently push the electrode tip down into the wet bristles
and rotate the probe 3–4 times. This will clean the inner surfaces of the
electrode as well as the platinum pin and reference junctions. REDOX 400
Calibration Fluid also performs a thorough chemical cleaning of the
platinum tip and the reference junctions during the calibration process.
Typical readings in established, well-maintained saltwater systems should
be in the 350–450mV range. Maintenance should be increased if the range
would fall to 225–275mV. Drinking water is considered sterilized at
REDOX/ORP values of 700–800mV. Artificial oxidation agents like potassium
permanganate or ozone gas must be monitored with a PINPOINT REDOX/ORP
Monitor™ to prevent overdose. Danger levels will vary according to
the livestock, however readings in the 500mV range should be examined
PINPOINT REDOX/ORP Electrode life is 18 months at which
time the probe should be replaced. While calibration may be possible on an
old probe, the probe's ability to react to changes in REDOX/ORP value will
be severely limited and therefore not adequate for
Important Points to
ORP Monitor has been designed as a continuous monitor. The AC
Adapter Kit is recommended however a regular 9-volt battery can be
successfully used until "LOBAT" is indicated on the display.
ORP meter is NOT waterproof and must be operated on a dry

corrosion and void warranty.
- The plastic storage container must be removed from the tip of the
probe so that REDOX/ORP values can be measured.
- Calibrate the REDOX/ORP probe to the PINPOINT Monitor by using PINPOINT REDOX/ORP
400 Calibration Fluid. For best accuracy the calibration should
be checked monthly with new 400mV fluid.
- If the probe is to be transported or stored, the plastic container
should be filled with storage solution (4.00 calibration fluid +
potassium chloride crystals) or 4.00 calibration fluid prior to being
installed onto the probe. Do not use deionized or reverse osmosis water
as storage fluid.
- Probe should be inserted about 1 inch into the liquid to be
measured. Probe may be totally submerged if desired.
- If several probes are used (i.e., pH and ORP, several pH, etc.)
space the probes 3–4 inches apart so that the probes will not react with
each other and yield erroneous readings.
- Clean the sensing glass, platinum tip and reference junctions of the
probe every few weeks by using a wet toothbrush or soaking the tip in
PINPOINT REDOX/ORP 400 Calibration Fluid.
- Replace the probe every 18 months for optimum performance.
- The PINPOINT ORP Electrode should be mounted vertically +/- 45
