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. Scales are easy to read - 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. Durable and attractive construction - 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. Easy installation - All Visi–Float® flowmeters have metal mounting inserts on rear for panel mounting. They can also be supported directly by system piping.

A handheld spectroscope for visible light shows the absorption lines of the elements involved in producing its color. For instance, it helps to separate ruby (chrome) against red or pink sapphire (iron). Spectroscope breaks up the light that is being transmitted from a gemstone to its spectral colors. The process allows the gemologist to see the various wavelengths absorbed by the gemstone. Thereby allowing the gemologist to know what elements(contained in the gemstone) that are causing the absorption. It is as one of the most important tools in identifying gemstones. Spectroscopes allow you to analyze a loose or mounted stone's spectrum. They help distinguish naturally colored diamonds from those that have been irradiated and help to distinguish natural stones from synthetics by the stone's selective absorption of certain wavelengths.The model GI-7206 is a graction type. Compared with the prism type GI-PS01 it is an economic type. It has a diffraction grating for the resolution of light of various wavelengths. Specifications: * Length: 55mm * Diameter: 15 mm * Material: Aluminum (Heavy Duty) * Inside Instruction: Diffraction Type * Heavy-duty and lightweight with its aluminum construction * Precise, Easy and very convenient to use * Durable, built to last long * A top quality instrument giving a brilliant spectrum Accessory included: * Leather Carry Pouch * Stylish Packaging box
