PINPOINT™ digital display monitors have been used by professional aquaculture all over the world 1991. PINPOINT monitors offer the most in value, performance and reliability. Every PINPOINT monitor is battery powered and come with a 2-year guarantee. These are true laboratory grade instruments with dedicated, replaceable probes. With proper care, the monitors should last a lifetime.

PINPOINT pH Monitor™ is in use by thousands of customers worldwide. This affordable unit remains the only full-time pH monitor with .01 resolution. The PINPOINT pH Monitor™ is sold complete with probe and calibration fluids (9 volt battery not included). The electrode is also available separately and fits any pH meter, monitor or computer controller.

PINPOINT ORP Monitor™ will measure the ORP (oxidation-reduction potential, commonly called 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. It is also popular for measurement of hydrogen rich water. 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. This unit features a 1mV digital resolution and a platinum sensor electrode. This is a full range REDOX/ORP instrument (–2000 to +2000 mV)

PINPOINT Conductivity Monitor™ is an instrument for the measurement of hardness in freshwater. The conversions are 33 µS=17.9 ppm=1dH. Good quality reverse osmosis water measures 5–15 µS, while de-ionized water typically measures 0–1 µS. The Conductivity Monitor is automatically temperature-compensated and has two ranges, making it useful for several different applications. Both freshwater fish keepers and those who use deionized/reverse osmosis systems often rely heavily on this meter.

PINPOINT Calcium Monitor™ is the only truly affordable and accurate digital calcium measurement instrument for marine saltwater. Powered by a 9-volt battery the PINPOINT Calcium Monitor™ will operate for approximately 150 hours before battery replacement is visually indicated on the display. The PINPOINT Calcium Monitor™ comes complete with Calcium Meter, Calcium Selective Probe and Calibration/probe fluids.

PINPOINT II Oxygen Monitor™ will quickly and accurately display a digital readout for dissolved oxygen in either % oxygen or ppm saturation. The measurement range is 00.0 – 20.0 ppm. The probe is a high performance polarographic type, which uses pre-loaded Teflon membrane caps and electrolyte fluid. This is the #1 preferred oxygen monitor in the aquaculture industry. The PINPOINT II Oxygen Monitor™ is an extremely good value, considering its high precision and ruggedness. The PINPOINT II Oxygen Monitor™ comes complete with Membrane caps and electrolyte fluid, a high performance probe with 5-foot cable and meter. Extra Membrane Cap/Fluid kits are available, and the 4-meter probe extension cord is an optional accessory. The commercial aquaculture market purchases a significant number of these units on a very regular basis. This meter is very field portable and fits inside a shirt pocket.

PINPOINT Salinity Monitor™ will accurately and immediately measure the amount of salt in any marine or freshwater system. The reading is fully temperature compensated, which is difficult or impossible with nearly any commercial hydrometer. The conversion chart will precisely show the corresponding density (specific gravity) or % salt (refractometer) values. This monitor is especially useful to determine the low level of salt required for Koi, whether in an aquarium or outdoor pond.

PINPOINT Wireless Thermometer™ will measure the temperature at the waterproof probe tip on the remote sensor(s), utilizing a radio wave signal, and will display the temperature in Fº or Cº degrees. The PINPOINT Wireless Thermometer can accept a maximum of 4 remote sensors, thus expanding the monitoring capability to 4 different locations to be displayed on the same PINPOINT Temperature Display Monitor (2-AAA batteries are required, but not included, for the meter and 2-AAA are required for each remote sensor). AC operation is not an option here because of the efficient power management of the electronics. Battery life is approximately 2 years.

PINPOINT pH Controller™ is an inexpensive yet rugged controller, which includes the appropriate probe and calibration fluids. This device will automate another electrical device such as a calcium reactor or magnetic solenoid for the addition of CO2 into an aquaculture or process system. This full feature controller will handle up to 5.0 amps at 110VAC. There is also a 220VAC version available.

PINPOINT ORP (REDOX) Controller™ is an inexpensive rugged controller complete with a platinum ORP probe. This device will automate another electrical device like an ozone generator. This full feature controller will accommodate an electrical device up to 5.0 amps at 110VAC. There is also a 220VAC version available.

PINPOINT Temperature Controller is a simple but rugged controller that can be used for a chiller or a heater or both a chiller and a heater. Fully programmable setpoints, Farenheit only readout and resolution to 1/10 of a degree, e.g. 78.6 F make this an easy choice for larger reef systems. Available 110VAC only.

PINPOINT AC Adapter Kit™ (110VAC) is optional to replace the 9-volt battery, which some monitor owners find convenient when monitoring full time. This AC adaptor kit now contains special electronic filtering to avoid electrical interference that was occasionally seen in the past from some lighting systems.

PINPOINT™ High-Precision Calibration Fluids: 4.000 +/- 0.002, 7.000 +/- 0.002. 10.000 +/- 0.005. These come in plastic envelope packets and are extremely accurate and field portable. Each packet contains ample fluid for calibration (about 30 ml). There is a free sample of these included with each PINPOINT pH Monitor™ and PINPOINT pH Controller. All electronic pH instruments should be calibrated monthly.

PINPOINT ORP/REDOX 400 Calibration Fluid. Another American Marine first. ORP/REDOX calibration fluid. With a precise measurement of 400mV this calibration fluid is included with every PINPOINT ORP Monitor and ORP Controller. Occasional retesting with this fluid will keep your readings dead-on accurate. Also very useful to determine if an ORP/REDOX probe is ready for replacement.

PINPOINT™ pH and ORP Replacement Electrodes are designed especially with your purpose in mind. They feature long, continuous duty expectancy, fast response and, most importantly, are non-toxic to your system. Each probe features a 10 foot cable with a high interference suppression jacket, Ag-AgCl reference, and the ORP probe is 99.9% pure platinum.
