Manufacturer: Red Sea Brand: Red Sea Model: RS7945

Red Sea’s Seawater Refractometer offers exceptional accuracy, for measuring the absolute salinity of seawater at a temperature of 25oC/77 0F. Most refractometers used within the aquarium hobby are not specifically designed for reef aquariums and use an algorithm for the measurement of brine (NaCl – rather than seawater) and at a temperature of 15oC/59 0F rather than 25oC/77 0F. Thus, a measurement deviation of up to 1.5ppt is possible, which can have a significant adverse effect on coral growth and coloration.

Each thermo-hydrometer comes with a Certificate of Conformance traceable to NIST. Bio-degradable, non-mercury performance liquid provides safe and easy cleanup in case of breakage. Scales are bold and easy to read. All instruments measure 15" in length and come with a built-in thermometer. Hydrometer cylinder of at least 390 mm x 50 mm is required. 1.000-1.220 Specific gravity range. 0.002 divisions. 20 - 150 degree F Thermometer range.

Manufacturer: Thermco Products Inc. Brand: THERMCO Model: GW2502C

Hydrometers are manufactured to the exacting specifications provided by NIST, ASTM/API and IRS and are calibrated against standards traceable to NIST. A certificate is provided with each hydrometer assuring that the user receives a quality instrument.

Manufacturer: GENERAL TOOLS & INSTRUMENTS Brand: General Tools & Instruments Model: REF114ATC

These Economy Refractometers are an excellent choice when occasional dissolved solids measurements are needed. The instruments feature adjustable focus and a zero-adjustment screw that make reading and calibration a snap. To use, just aim the front end of the instrument at a bright light, turn the adjusting ring until the reticule can be clearly seen, open the cover plate and add a few drops of distilled water to the prism, and then close the cover plate and press lightly. The correcting screw can be used to align the light/dark boundary with the null line. Choose from standard units calibrated and adjusted to read at 20°C or models with Automatic Temperature Compensation (ATC) for applications where the temperatures of your sample vary. Each refractometer includes hard case, calibration screw driver and instructions.
