Hanna Instruments Multi-Range Conductivity Meters are portable, waterproof multi-range conductivity meters designed for use in production and quality control. An LCD screen provides instructional prompts and the meters come with a cabled probe. The meters have multiple ranges for testing a variety of samples, from deionized water to brine. 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. 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 selection. Conductivity meters are used in research laboratories and a variety of industries, such as water-quality testing, waste-water treatment, hydroponics, agriculture, aquaculture, and cosmetics manufacturing. Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) standard 9001.

Consists of a heavy cast base and a pillar for collimator support. The telescope arm moves along a fixed circular plate 150mm diameter graduated in degrees. This Advanced Spectrometer has a double ended vernier for better and accurate measurements, with a least count of 30”. Fine adjustment is accomplished by using a knob while the coarse adjustment can be done by hand. Both the collimator and the telescope are mounted with an axis adjustment system. The telescope has a 10X Ramsden eyepiece and is fitted with a cross hair reticle. Both the telescope and the collimator are fitted with coated achromatic objectives of 178mm focal length and 32mm diameter, providing light for a brighter and sharper image. The focussing is done by a concealed rack and pinion. The collimator slit 6mm long, is specially designed for retention of initial accuracy during the life of the instrument. The prism table 75mm diameter is held with the help of a clamping screw enabling the table to be rotated in any direction. It has lines and concentric rings marked to assist positioning of prism in relation to levelling screws. It is fitted with a diffraction grating holder of aperture 25mm x 25mm and a clamp for holding prisms (not included) up to 38mm high.What's in the Box?SpectrometerDiffraction gratingPolystyrene foam caseInstructions
