ATAGO™ Abbe Refractometer NAR-1T

Descrizione

• These Abbe refractometers provide highly accurate refractive index and Brix measurements of liquids and solids.
• Place your sample on the main prism, which is rimmed with stainless steel to prevent corrosion, look through the eyepiece and line up the shadowline in the crosshairs.
• The built-in 589 nm illuminator light source provides stable, monochromatic light (02939-00, -02 include LED light source), making it easy to read the black lines on the green field.
• The frosted secondary prism directs light to the main prism evenly, and lifts up for easy placement of solids and viscous liquids on the main prism.
• The color compensator knob allows you to adjust the boundary line for higher clarity and fine tuning capability for greater resolution. Use the color compensation knob and a conversion table to measure dispersion (variance of RI with different wavelengths of light).
• In order to maintain constant temperature at both prisms, these refractometers include four 9 mm OD ports (using 6 to 7 mm ID tubing) for connections to a constant-temperature bath.
• A thermistor thermometer for measuring temperature is built into the main prism.
• The temperature of the main prism is indicated on the LCD from 0°C to 50°C with ±0.2°C accuracy; a digital temperature display unit is included.
• The built-in desiccant chamber removes moisture from internal optics ensuring an unobstructed view of scales.
