Antifreeze refractometers are designed to test the concentration of battery fluids, antifreeze liquid and cleaning fluids. The indicated percentage show 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 battery solutions. This model uses °C unit system chart. With the indication of the percentage you will know the freezing point of either ethylene or propylene glycol based cooling systems. Also, it can be used to test the concentration of ethylene or propylene glycol in antifreeze liquids. Ideal for field use - the refractometer has ATC (Automatic Temperature Compensation) for precise measurement without having to re-calibrate after changes in ambient working temperature. Features * With Built-in Calibration Knob, no need for a mini-screwdriver * Needs ambient light only during test * Adjustable manual focusing * Soft rubber eye piece for comfortable viewing * Accurate testing results guaranteed * Extremely focus and easy-to-use * With non-slip grip * Clear chart, easy and comfortable reading of results * Made w/ highest and finest quality of aluminum & rubber making it lightweight, durable and last long Specifications Measuring Range: Ethylene Glycol: -60 - 0°C (0-66.6%) Propylene Glycol: -50 - 0°C (0-62.4%) Battery Fluids: 1.100 - 1.400sg Resolution Factor: Ethylene Glycol: 5°C Propylene Glycol: 5°C Battery Fluids: 0.01sg Automatic Temperature Compensation (ATC): 10-30°C (50-86°F) Set Includes 1 x Refractometer with Built-in Calibration Knob 1 x English Instruction Manual 1 x Pipette Sturdy Plastic carrying case

The Visi-Float® flowmeter bodies are cut and precision machined from solid, clear acrylic plastic blocks. This construction not only produces a handsome finished product, but permits complete visual inspection. As a result, the Visi-Float® flowmeters are especially popular for medical and laboratory equipment applications. The front scale location and white background provides excellent visibility. The direct reading scales are hot stamped into the plastic and will not wear off. Mid-range calibration is established with a master flowmeter. Accuracy is ±5% of full scale for VFA models, ±3% for VFB. Scales average 2" long on the VFA models, 4" long on VFB. The machined acrylic bodies of the Visi-Float® flowmeters are practically unbreakable. Fabrication is backed by over 60 years of experience in acrylic instrument machining. The tapered bore is precision machined to a smooth surface that provides perfect visibility of the indicating float. The VFA and VFB models are available with either brass or stainless steel inlet and outlet connections and are tapped for 1/8" NPT thread. VFB models 85 and 86 have either 1/4" back or 3/8" end connections. All standard models employ Buna-N o-rings for leak proof operation and are available with either back or end connections for horizontal or vertical piping. Precision metering valves in brass or stainless steel are available for most VFA and VFB models. All Visi-Float® flowmeters have metal mounting inserts on rear for panel mounting. They can also be supported directly by system piping. (Standard range shown in picture).
