RHA-503ATC models are equipped with °C unit system. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol-based cooling systems. And they can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze liquids. There's also an additional scale for measuring the freezing point of windshield cleaning fluid. It's FULLY EQUIPPED with ATC that automatically adjust itself to correct temperature discrepancies during use. Refractive index is very temperature dependent, it is important to use a refractometer with automatic temperature compensation to give you the most accurate measurement in any type of environment temperature. Capable of measuring with high accuracy and provides precise results. It's equipped with vivid and sharp reticle chart for easy and comfortable reading. It uses ambient light only and no batteries are needed. Made by experienced craftsmen and are unlikely to break down! Get the RHA-503ATC and be able to measure four main types of Antifreeze/Battery/Cleaning Fluids!

Measuring Range: 1.30 - 1.81 RI Minimum Graduation (RI): 0.01 RI Illumination: Internal illumination with momentary switch Size: 30mm x 70mm x 130mm Scale Division: 0.01 nD Weight: 0.4 kg Ranges of Application: Laboratory, Gemology Filter: Polarizing filter Made of durable heavy metal and scratch proof glass This item is commonly known as Gemstone Refractometer, is the primary and most powerful tool in identifying and authenticating polished precious and semiprecious gemstones and also observing the optical properties and the structure of gemstones. This model is just as good as the expensive models used in gemological institutes, it has a built-in light source and with the aid of the Contact liquid (RI Fluid), which creates an optical contact between the glass and the gemstone, you can measure or test the Refractive Index of faceted stones, its transparency or opacity, and its beauty, durability and scarcity. The refractive index (RI) of a gemstone provides the single most important piece of information to a gemologist seeking to identify an unknown stone. Due to its chemical composition and crystallization structure, each gem has a typical refractive index. In fact, you can also use this tool to measure R.I. for many minerals in crystal form as long as the crystals have a flat and polished face. Through these parameters, you can determine whether the gem is a Single Refraction (Isotropic) or Double Refraction (Anisotropic or Birefringence).

Manufacturer: Grand Index Brand: Grand Index

This hand-held optical refractometer measures the density of sugars in the solution and gives you an instant gravity readings at any point during the boil, or run off from the mash. You do not need to convert the reading from Brix to specific gravity or do an adjustments for temperature. Great for quick and frequent check on the gravity of your running or while sparging, and also for those who do not like to deal with the temperature compensation necessary with a hydrometer. Unlike a hydrometer, it only requires a very small amount sample, about 2-3 drops of sample only. This refractometer is specifically created for brewing of BEER but it can also be great for: Fruits, vegetables & grasses: Monitor and control sugar concentrations in foods, beverages, crops and plants, checking the "ripeness"of fruit in the field and verifying product quality after harvesting and/or controlling concentrations during processing and packaging to ensure product quality Wine or beer: Use Brix readings to get wort sugars and help determine finished alcohol readings (for alcohol reading, best use in conjunction with a hydrometer) Metalworking fluids: Helps in maintenance of CNC coolants and water soluble drawing & stamping compounds and commonly used for controlling the concentration of various industrial fluids like cutting lubricants and flux rinsing compounds The need to consult temperature correction charts is eliminated with the built-in 10-30°C ATC. The unit also comes with a manual calibration knob that is secured with a lock nut and has a brighter display than the more narrow range refractometers. One of the popular instrument with many homebrewers! Measuring Range: 0-32%Brix; SG: 1.000-1.130 Minimum Division: 0.2%Brix; 0.001sg

Manufacturer: Cole-Parmer Brand: Extech Model: RF20

Use these refractometers to take accurate and repeatable measurements of sugar, salt, lubricants, antifreeze, cutting fluids, and more! simply place 2 or 3 drops of your sample on the prism; the focus adjustment makes the scale easy to read. Automatic temperature compensation ensures accurate readings from 50 to 86°f (10 to 30°c). includes calibration solution to ensure accurate results.
