Erma  range of hand held refractometers are ideal for use in beverage, confectionery, jam and other sugar applications as well as for calculating concentration or blend ratios in industry such as antifreeze, coolants and quenchants.

The instruments are particularly suited for testing semi-solid substances such as apples, melons, grapes sugar beet and potatoes during the harvest period in order to establish fruit ripeness. Juice from the product may be squeezed onto the prism surface or alternatively a slice 2mm thick may be placed on the prism surface for direct reading of sugar content.

The instruments feature an internal device that corrects for temperature (ATC) making the measurement fast and accurate. The device will automatically take into account any difference in temperature over the range 10-30°C from the industry standard reference temperature of 20°C.

This refractometer is particularly suitable for measuring the sugar content of honey, jams, syrups, etc. Accurate, yet easy to use: simply place a few drops of liquid on the prism and the density is directly readable.

Portable Hand-held Refractometer Features : Used to measure the salinity and specific gravity of the water. Sturdy and light weighted Aluminum body. Superior quality rubber grip. High quality and accurate testing result. Can be easily calibrated with a mini-screw driver. Automatic temperature compensation (ATC) Easy to use, convenient to carry. Specifications : Size(approx) : 195 x 40mm

This dual scale salinity refractometer is used to measure, monitor and control the concentration of salt water and brine, especially useful for aquarium and marine applications. This high quality refractometer measures on 2 scales, specific gravity (D 20/20) and parts per thousand and replaces your poor quality and difficult to read hydrometer. With just a couple of drops of aquarium water you know exactly what your salinity is.

RHB-62 refractometer is developed for working with sugar related liquids (fruit juices, soft drinks, wine), help monitor and control sugar concentrations in foods and beverages. Whether users are checking the “ripeness” of fruit in the field, verifying product quality after harvesting, or controlling concentrations during processing and packaging, refractometers provide critical information to ensure product quality. But,it is also commonly used for controlling the concentration of various industrial fluids cutting lubricants and flux rinsing compounds). Full ranges of measurement is available.

This optical refractometer (brix meter) is equipped with a Brix scale in range from 58 to 92 °Bx (% mas sucrose). The measurement precision is ±0.2 °Bx. Is suitable for measurement of condensed milk, vegetable oils, sugar syrups, fruit jams, molasses, water-based adhesives and glues etc.

Example: if you measure value 25 °Bx it means that in the 100 g of aqueous solution is dissolved 25 g of sucrose. In other words, in 100 g of aqueous sucrose solution is 25 g of sucrose and 75 g of water. That is why is sometimes used the percent sign (%) as a unit because the sucrose content is a sucrose percentage by weight.
