American Marine PINPOINT ORP Monitor** |
PINPOINT ORP Monitor™
PINPOINT
ORP Monitor will measure the ORP (oxidation-reduction potential,
or REDOX) of your system. It is popular with those who use ozone gas
or potassium permanganate as an artificial oxidation agent in fresh
or saltwater. Constant monitoring of the ORP is useful in keeping tabs
on the overall health of a system, as a drop in ORP often precedes visual
or other indications of trouble. Many serious marine enthusiasts who
do not use ozone gas use this meter to judge the overall health of their
reef systems. This unit features a 1mV digital resolution and a platinum
electrode. Comes complete with meter and probe.
- Given
proper care, the PINPOINT ORP Monitor should last
a lifetime.
- PINPOINT
ORP Probe comes with a 10 foot high supression cable and a BNC
connector.
- The
range is 2000 to +2000 mV.
- Powered
by a standard 9-volt battery (not included).
- Replacement
ORP probe and Optional AC Adaptor Kit available.
American
Marine is proud to introduce PINPOINT ORP Monitor,
the only truly accurate and affordable continuous monitoring ORP (REDOX)
system. Every PINPOINT ORP Electrode features a 10-foot
wire cord and standard BNC Connector as well as a full platinum band
(not a wire strand as in pens and lesser quality electrodes). 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 when visually indicated on the display as "LOBAT".
NOTE: The 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 warranty.
Set-up
Unwrap the protective plastic packaging from the PINPOINT
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. Carefully remove the plastic storage cap installed on the end
of the electrode. A small amount of storage fluid will be expelled,
this is normal. There may also be traces of a white crystalline powder
(KCL) on the outside of the clear plastic cap which can easily be washed
away with tap water. SAVE the plastic storage cap 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. The probe may be totally submerged. Attach the BNC Connector
from the electrode onto the BNC input of the ORP Monitor. Turn the connector
1/4 turn clockwise to lock the connector. Activate the unit by setting
the power switch to the ON position. Your PINPOINT ORP Monitor
is now ready for use.
As with any high quality ORP Electrode please wait a full 24-36 hours
before recording ORP values. During this period the electrode should
"settle in" when placed in a salt-water environment.
The PINPOINT ORP Electrode is widely considered to be
a superior grade and does not require any calibration or adjustment.
As a very approximate guide the ORP measurement of deionized (or reverse
osmosis) water and regular household liquid bleach (5 parts water/1
part bleach) should measure about 700 when the temperature of this liquid
is about 68°F. The electrode should be replaced every 18-20 months
with a new PINPOINT ORP Electrode.
The calibration offset adjustment is located inside the battery compartment.
It is recommended that the offset adjustment labeled as O not be adjusted
unless the user is absolutely certain of their calibration materials.
As shipped to the consumer, this adjustment is made at the factory and
does not require any other adjustment. Clean the 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 glass bulb surface, platinum band and reference junctions.
Typical readings in established, well-maintained saltwater systems should
be in the 350-450 range. Maintenance should be increased if the range
would fall to 225-275. Artificial oxidation agents like potassium permanganate
or ozone gas must be monitored with a PINPOINT ORP Monitor
to prevent overdose. Danger levels will vary according to the livestock
however readings in the 500 mV range should be examined closely.
Important Points to Remember
- PINPOINT
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.
- PINPOINT
ORP meter is NOT waterproof and must be operated on a dry surface.
Liquid contact with the printed circuit board will cause corrosion
and void warranty.
- The
clear plastic cap must be removed from the tip of the probe so that
ORP values can be measured. A small amount of storage liquid will
be expelled; this is normal.
- There
may be some white salt-like residue (potassium chloride crystals)
around the clear plastic cap. This is normal and should be washed
off with water.
- Keep
the sensing surface of the probe WET at all times. If the probe
is to be transported or stored, the plastic cap must be filled with
storage solution (4.00 calibration fluid + potassium chloride crystals)
or 4.00 calibration fluid prior to being installed onto the probe.
- 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 band and reference junctions of the
probe every few weeks by using only a wet toothbrush.
- Replace
the probe every 18-20 months for optimum performance.
- The
PINPOINT ORP Electrode should be mounted vertically +/- 45 degrees.
- Do
not allow air bubbles to accumulate under a vertically installed
electrode.
