Experience precise and reliable measurements with this professional refractometer, designed for high accuracy and ease of use. Perfect for various applications, including testing cutting fluids and salinity levels, this refractometer ensures accurate results with a clear calibration scale that is easy to read. Featuring a comfortable, ergonomic, and non-slip handle, it offers convenient handling for extended use. Choose from three types to suit your needs: cutting fluid testers with different measuring ranges or a salinometer for salinity measurements. Key Features: · High Precision Measurement: Provides accurate and consistent test results for cutting fluids and salinity concentration. · Clear Calibration Scale: Easy-to-read measurement scale enhances usability and reduces reading errors. · Comfortable and Non-Slip Handle: Ergonomic design ensures secure grip and comfortable operation. · Multiple Types Available: Includes cutting fluid testers (0-32%, 0-20%) and a salinometer (0-100‰) to cater to different measurement requirements. · Portable and Lightweight: Compact design with lengths around 17cm and lightweight construction (approximately 219g–245g), ideal for field or laboratory use. · Complete Kit Included: Comes with a screwdriver for calibration, a pipette for sample application, a cleaning cloth, and a protective storage box. Specifications: · Type Options: Cutting Fluid Tester (#1: 0-32%, #2: 0-20%), Salinometer (#3: 0-100‰) · Minimum Scale: 0.2% (Cutting Fluid Tester #1), 0.1% (Cutting Fluid Tester #2), 1‰ (Salinometer) · Length: Approx. 17 cm (6.7 inches) · Weight: Approx. 219g to 245g depending on model Instructions for Use: 1. Open the cover and clean the prism surface with a soft cloth before use. 2. Place a few drops of your test solution on the prism, then gently close the cover to avoid bubbles and ensure even spread. 3. Face the refractometer towards a light source and look through the eyepiece. 4. Adjust the eyepiece focus using the hand wheel until the blue and white boundary line is sharp and clear; the scale on the dividing line indicates the concentration of the solution. Care and Maintenance: · Handle with care to avoid impacts, shocks, or dropping. Do not loosen components arbitrarily. · Clean only with a soft, dry cloth; avoid immersion in water or abrasive cleaning methods. · Store in a dry, non-corrosive environment to protect the instrument’s accuracy and longevity. · Avoid over-adjusting the eyepiece beyond the 2 cm left or right range to prevent damage. Package Includes: · 1 x Refractometer · 1 x Screwdriver · 1 x Pipette · 1 x Cleaning Cloth · 1 x Protective Box This precise and easy-to-use refractometer is an essential tool for professionals and hobbyists who require accurate fluid concentration measurements. Its robust build, convenient calibration, and comprehensive accessories package ensure reliable performance for monitoring cutting fluids, salinity, and other liquid solutions.
