The Captive Purity Refractometer is an incredibly accurate and easy to use device that eliminates the confusion associated with inexpensive hydrometers. Just place a couple of drops of water on the prism and hold to the light. Reads in percent and specific gravity. An absolute must for the serious marine hobbyist. The Captive Purity Refractometer is an optical device (no batteries) dual scaled 0-100% specific gravity: 1. 0 to 1. 070. Calibrate with distilled water. Adjustable eyepiece, carrying case, pipette and calibration screw driver included. This model is ATC (automatic temperature compensating)

NYOS NITRATE REEFER TEST KITThe NYOS Nitrate Reefer test kit is one of the cheapest most accurate test kits available. The NYOS test kits are very accurate and are the best choice for saltwater reef tanks when water parameters are most important.Water properties as close to nature are the key for every aquarium's success. However, monitoring relevant parameters in seawater is difficult due to numerous interfering ions. Therefore, test kits considering the specific characteristics of seawater are needed to analyse the water precisely.NYOS REEFER test kits offer the customer two significant benefits:Highly precise analyses for seawater conditions. Furthermore, they offer a highly attractive price-performance ration and make test kits in laboratory quality affordable for the standard hobby user.Additional characteristics of our REEFER test kits: * calibrated dropper made by a German manufacturer ensures uniform drops during all repeat tests * reagents are made in Germany in accordance with EN ISO 9001 * reagents are analysed according to AAS and NIST standards * strict batch and quality control * easy to use with intuitive pictogram instructions * Made in GermanyNYOS REEFER test kits allows you to achieve precise and most importantly reproducible (i.e. in repeat measurements identical) measuring results.Number of Tests: 40
A very simple test for 8 heavy metals that anyone can use at home giving results in minutes. The results have been independently verified by a laboratory in Canada, Kemetco Research Lab. A very good preliminary test for the presence of heavy metals before going for more extensive testing.

This kit is capable of at least 75 tests for magnesium. It is designed specifically for seawater. The test is based on titration of magnesium with EDTA in the presence of a magnesium specific indicator dye after the coprecipitation of calcium and strontium. Natural seawater concentration for magnesium is approximately 1,300 mg/L. The magnesium concentration in kalkwasser treated aquaria may be as low as 600 – 700 mg/L. In general, it is prudent to maintain magnesium concentrations in reef aquaria between 1,200–1,400 mg/L. If magnesium levels are found to be deficient, Seachem recommends the use of Reef Advantage Magnesium® (ammonia free! unlike competing liquid magnesium supplements). Seachem also offers other reef specific test kits: Reef Status™: Strontium, Reef Status™: Calcium and MultiTest™: Reef Special (tests for phosphate, silicate and iodide).

Same method used by professional Wineries to determine the acidity level of a must before fermentation and again at bottling time. Measured amounts of reagent is added to a measured sample of juice or wine that has been prepared with indicator solution. When the sample changes color, the acidity is determined by measuring the amount of reagent used to obtain the color change. Includes: a Test tube, measuring syringe, reagent, indicator solution and complete Instructions.
American Marine PINPOINT Salinity Monitor + Calibration Fluid
Manufacturer: American Marine
Brand: American Marine
American Marine PINPOINT Salinity Monitor PINPOINT Salinity MonitorTM will accurately and immediately measure the amount of salt in any marine or freshwater system. The reading is fully temperature compensated and the conversion chart will precisely show the corresponding density (specific gravity) or % salt (refractometer) values. Every saltwater aquarist should own this monitor . the accuracy is superb! This monitor is especially useful to determine the low level of salt required for Koi, whether in an aquarium or outdoor pond. Comes complete with meter, probe and calibration fluid.
