Features:
(1). DRB series Digital Refractometer for Brix are 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). This instrument is equipped with an Automatic Temperature Compensation System making it ideal for field use.
(2). The DRS series are developed for measuring the concentration of ketchup, mayonnaise, pickle juice, salt water and brine. The DRS series proves themselves invaluable for agriculture, food processing and wildlife management. This instrument is equipped with an Automatic Temperature Compensation System making it ideal for field use.
(3). The DRH-300 is specially designed for measuring the refractive index, Baume, Warter of honey
(4). The digital ¡ãOe Testers are ideal for concentrated fruit juice and canned foods that use a sugar infusion.It has four scales: Oechsle(Oe¡ã), MASS s/v(Brix), AP and KMW.
(5). The DRA series are designed for measuring the concentration of the battery fluids. the freezing point of antifreeze liquid and windshield cleaning fluid. With the indication of the percentage you may know at which temperature the fluid will be frozen for both propylene glycol and ethylene glycol. It can also be used for checking the strength of electrolyte solution battery.
(6). The DRC series are designed for clinical usage and intended for both Veterinary and Human Being. This unit provides veterinarians and Human Being with quick and accurate indication of vital fluids levels. It can read urine specific gravity, total serum protein and refractive index.
