Hydrometers & Refractometers

Tropic Eden Salinity Calibration Solution The Tropic Eden Salinity Calibration comes in a set of two bottles (one bottle of 35ppt of ~5-6ml, and one bottle of 0ppt of ~5-6ml).One set is good for about 50 calibrations which should be enough for well over a couple of years for most people.Each calibration takes only 2-3 drops, and each bottle has more than 150 drops.

Tropic Eden Salinity Refractometer A refractometer designed for measuring actual seawater (not brine!) in the same temperature range of the typical reef aquarium. These simple facts are what set this refractometer apart from the vast majority available in the aquarium industry. The Pro-1 Normal Seawater Refractometer of Tropic Eden can determine the salinity & specific gravity of natural or artificial seawater, oceanic water, and brackish water intermediate with extreme accuracy and reliability.The Pro-1 is meticulously designed according to the optical properties of normal seawater, based on the proportional sum function of the refractive index (RI) of all 70+ major, minor and trace elements, further taking into account temperature factor and the mean of natural seawater samples obtained from more than 120 locations in the sea and coral reefs around the world.The Pro-1 is highly precise and well built with special high density alloy for immediate heat conduction, and crisp high quality lens, which is quick and easy to use for laboratories, seawater marine aquariums and research out in the field. Specifications of the TE Salinity Refractometer Type: Full Spectrum Seawater Scale Range: 0-45ppt (full spectrum seawater), 1.000-1.035 S.G. @ 78.8deg F / 26deg C Division: 0.1%ppt / s.g. 0.001 Temp Range: Automatic Temperature Compensation 59-113deg F / 15-45deg C Accuracy: +/- 0.2% Weight of unit: 260 grams Dimensions of unit: 1.2" x 1.2" x 7.4" Other Features of the Tropic Eden Refractometer Easy calibration with distilled water Ruggedized cardboard case w/ included fabric bag. Pipette & calibration screwdriver included.

Hygger Hydrometer The hygger aquarium hydrometer is accurate and reliable aquarium salinity tester. It delivers precise full-range salinity and specific gravity readings. This also includes a built-in base so you can rest the hydrometer on a counter top or other flat surface when taking salt readings. The salinity tester is best used with brackish and marine aquariums. and includes specific gravity and salinity PPT Scales The hydrometer supplies an optimal specific gravity/salinity range indicator and a bubble diffuser on water intake prevents micro-bubbles from forming on the needle. The salinity tester is made of transparent acrylic material, which is relatively hard and easy to read. Easy-to-Read Marine Hydrometer. Hygger Hydrometer Specifications Temperature-corrected and accurate to +/-0.001. Specific Gravity Range: 1. 000-1. 030 (ppt value: 0-43.9 degrees) Safe Area for Marine Aquariums: 1.020-1.023 (ppt value: 30.2-34.2 degrees) Low Specific Gravity Area 1.000-1.019 (ppt value: 0- 28.9 degrees) Higher Specific Gravity Area 1.024-1.030 (ppt value: 35.5-43.9 degrees). Using the Hygger Hydrometer Insert the hydrometer into the tank or the fish pond until the plate spills. (slowly filling to prevent bubbles from attached to the pointer) When the hydrometer is full, take out the hydrometer and place it on a horizontal surface. Read the specific gravity according to the inner scale, and read out the salinity (PPT) according to the outside scale. Rinse with clean freshwater after each use.
