PA202X and PA203X Misco Palm Abbe Digital Seawater Refractometer

The MISCO Palm Abbe AQUAR™ digital refractometers are engineered specifically for measuring the physical properties of seawater, saltwater and brackish ocean water.  The AQUAR Digital Seawater Refractometer is the first refractometer in the world able to express results in Practical Salinity Units (PSU), while also providing an instant digital field-determination of specific gravity, density, sigma-t, conductivity, and Chlorinity.

Designed specifically for oceanography, aquaculture, professional aquariums, desalination plants, and research, the MISCO AQUAR Digital Seawater Refractometer is equally at home on ship or on shore.  It achieves higher accuracy and overcomes many of the limitations of other test methods including chloride titration, hydrometers, and conductivity meters.

The AQUAR series refractometers are based on the accepted physical properties of seawater, and the latest scientific research, as published by the United Nations Educational, Scientific & Cultural Organization (UNESCO) and others.  It is this seawater basis that separates the MISCO AQUAR refractometers from other refractometers that are based on only sodium chloride.  The user may select from a number of physical properties of interest including, salinity expressed in Practical Salinity Units (PSU), specific gravity and density at a number of reference temperatures, sigma-t, and conductivity.

The Palm Abbe AQUAR refractometer requires only a couple of drops of seawater to fill its stainless-steel sample well and the sapphire optics, the next hardest substance to diamond, will withstand years of wear and tear.  A simple, user-friendly interface consists of two buttons: one to take readings and the other to step through various menu options.  The large 24-character LCD display is easily read, even in dim light, and an evaporation cover helps prevent evaporation and keeps out stray light.

Protection against inaccurate readings due to temperature differences, a major concern with refractometer measurements, is assured with nonlinear temperature compensation specific to seawater.  Temperature compensation is automatic for fluids read between 0 and 50 °C (+32 to 122°F).  Calibration of the AQUAR is automatic and does not require special calibration solutions or tools; they automatically calibrate themselves to water.

Adding a Rubber Armor Jacket to a Palm Abbe refractometer increases its durability and provides a better grip.  Made of high-grade silicone rubber, the Rubber Armor Jacket is custom fit and will help protect your Palm Abbe from minor bumps and scratches.

Custom contoured bumpers provide a soft, firm grip while also adding additional shock protection.  The Rubber Armor Jacket is soft to the touch and fits the Palm Abbe like a glove.  It is easily slid over the refractometer and does not have to be removed before use.

The durable jacket is tear and chemical resistant and weighs only 1.8 oz. (51 grams).  There is even a hole on top for a carabiner (included) so that you can hang the Palm Abbe refractometer from your belt loop.  The form-fitting Rubber Armor Jacket fits the Palm Abbe PA201, PA202, and PA203 series instruments and comes in three colors (black, gray, and safety orange).

Although the Rubber Armor Jacket is not guaranteed to completely protect your instrument from damage due to shocks and impacts, it does provide an additional layer of protection and provides a better grip to help you avoid dropping it in the first place.

Need proof? Our rugged Proof Case is water-proof, crush-proof, dirt-proof, dust-proof, drop-proof, rain-proof, snow-proof, sink-proof, even goof-proof. It is perfect for providing an additional level of protection when you use your Palm Abbe in demanding environments or when you just want to know that your instrument is safely stored.

The virtually indestructible case has a fitted foam insert that cushions the Palm Abbe in the event of rough handling. Two heavy-duty latches secure the lid against an integral O-ring providing a waterproof seal to 100 feet (30.5 meters) under water.

NIST Traceable Certified Refractometer Calibrations - The MISCO Refractometer Certified Calibration program provides all the requirements for the confirmation of calibration accuracies for refractometers and for the preparation and control of measurement standards traceable to the U.S. National Institute of Standards & Technology (NIST). The intention of this program is to minimize uncertainty of measurements and minimize the risk of refractometers producing results having unacceptable errors. This program is compliant with International Standard ISO 17025.
