The Hydrometer is an instrument which is constructed on the Archimedes principle that a solid body displaces its own weight of the liquid in which it floats. Hydrometers can be divided into two general classes; namely for liquids heavier than water and for liquids lighter than water. The base hydrometer scale is Specific Gravity, in which distilled water equals 1.000 as the initial point. Liquids lighter than water are scaled below 1.000 specific gravity and liquids heavier than water are scaled above 1.000 specific gravity. Hydrometers are usually calibrated at 60°F/60°F. To determine the density of a liquid, the liquid should be at 60°F. If the temperature varies, the liquid will either contract or expand, depending upon the temperature. Where there is a variation from the standard 60°F, corrections must be applied to the hydrometer reading. To assure proper corrections, a separate accurate thermometer should be used, or a hydrometer in combination with a thermometer, which is sometimes referred to as a "thermohydrometer."

Manufacturer: Sper Scientific Brand: Sper Scientific Model: 300006

Salt Refractometer 0 ~ 28% Measures salt content in sea water, pickling-brines and other applications. While the scale is calibrated for sodium chloride, it can also be used for calcium chloride, barium cobalt, magnesium, cesium, potassium, sodium chloride, cupric sulfate, potassium iodide, citric acid, acetic acid and (vinegar).Place a drop or two of a sample on the prism and read the results. Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. A refractometer measures the extent to which light is bent (refracted) through a liquid sample. They are commonly used to help identify or confirm the identity of a sample, assess the purity of a sample, or determine the concentration of a solute in a solution. They can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care, their reliability, precision, and optical performance will last forever. All Sper Scientific refractometers come complete with: • Rubber coated hand grip and construction, which insulate the test solution from inaccuracies caused by the user's body heat.• Covered eye piece and bright, clearly defined scale, with large easy-to-read measurements.• All the accessories for immediate use, including calibration tools and solutions, full instructions, transfer pipettes and protective cases. Dimensions: 6½" × 1½" (165 × 38 mm) Weight: 3.0 oz. (86 g).

Manufacturer: Thermco Products Inc. Brand: THERMCO Model: 1221F15EA

Thermco’s Plastic Hydrometers are fabricated from polycarbonate (PC) which makes the instrument shatter-proof, while offering glass-like clarity for ease of reading. All models are plain form, so a separate hermometer should be used to measure the temperature of the sample and correct for any temperature variations.

Manufacturer: Thermco Products Inc. Brand: THERMCO Model: GW2601

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: Hanna Instruments Brand: Hanna Instruments Model: PRIMO2

The Hanna Instruments Primo 2 is a total dissolved solids (TDS) and temperature tester for water quality applications, with automatic temperature compensation, automatic calibration, and automatic shutoff after five minutes of non-use. The meter is operated by two buttons at the top: one for TDS and one for temperature. It has a direct probe connection. Conductivity meters are commonly used in the water-quality testing, waste-water treatment, hydroponics, agriculture, and aquaculture industries, in cosmetics manufacturing, and in laboratory research.Specifications Range 0 to 1999ppm (mg/L) and 0.0 to 60.0 degrees C Resolution 1ppm (mg/L) / 0.1 degrees C Accuracy + or - 2% Full Scale / + or - 0.5 degrees C Calibration Automatic, at 1382ppm Temperature compensation Automatic, 0 to 60 degrees C (32 to 140 degrees F), temperature coefficient equal to 2% per degree C Power source Two 1.5V batteries (included) Dimensions (meter only)180 x 50 x 25 mm / 7.1 x 2.0 x 1.0 inches (H x W x D) Weight 227g / 8oz  H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. Conductivity meters, also known as electrical conductivity (EC) meters, measure the ability of a solution or material to conduct an electrical current. This measurement helps determine if the solution is, for example, contaminated or contains too much saline. In general, pure solutions, such as distilled water, have low conductivity. More saline- or nutrient-rich solutions, such as seawater or fertilizers, have high conductivity. Conductivity measurements are often used with total dissolved solids (TDS) measurements, which are typically expressed in ppm (parts per million). TDS consist of dissolved minerals and salts. To determine the amount of TDS, conductivity is measured, and the result is converted to a TDS measurement. Different meters provide results for conductivity, TDS, or both, and the application determines meter s...
