₹1,049.00 (Inclusive of all taxes)
Out of Stock

This handheld optical refractometer provides a direct, battery-free method for measuring alcohol content by volume (v/v) in distilled spirits. It features automatic temperature compensation (ATC) for stable readings between 10°C and 30°C and is ideal for use in distilleries, quality control labs, and retail settings.

Features

  • Measures alcohol content by volume (v/v) across a 0-80% range with 1% v/v resolution.
  • Automatic Temperature Compensation (ATC) ensures accuracy between 10°C and 30°C.
  • Zero-calibrated with distilled water at 20°C for reliable baseline measurements.
  • Operates using ambient light, requiring no batteries or external power source.
  • Includes protective carrying case, pipette, and calibration screwdriver for field use.

Description

This handheld refractometer operates on the principle of light refraction through a liquid sample to determine its alcohol concentration. The instrument is factory-calibrated using distilled water and incorporates an Automatic Temperature Compensation (ATC) mechanism to correct for ambient temperature variations between 10°C and 30°C, ensuring measurement stability without manual adjustment.

Designed for portability and ease of use in non-laboratory environments, it provides a quick and reliable method for assessing the alcohol content of distilled spirits such as whiskey, vodka, gin, and brandy. Its durable construction and included protective case make it suitable for fieldwork, production line checks, and quality assurance applications.

Key Features

  • Optical Measurement: Determines alcohol content by mass/volume via refractive index, requiring no electrical power.
  • Wide Measurement Range: Covers 0% to 80% alcohol by volume (v/v) with a clear single scale.
  • Integrated ATC: Automatic temperature compensation from 10°C to 30°C for accurate readings in variable conditions.
  • Simple Calibration: Pre-calibrated with distilled water; includes mini-screwdriver for field recalibration if needed.
  • Portable & Durable: Housed in a compact, impact-resistant body with a dedicated protective carrying case.
  • Complete Field Kit: Supplied with essential accessories including a pipette for sample handling.

Applications

  • Quality control and proofing of distilled spirits (whiskey, vodka, gin, brandy) in distilleries.
  • Alcohol content verification for bottling lines and retail compliance checks.
  • Educational and research applications in chemistry and food science laboratories.
  • Field testing for home brewers and craft spirit producers.
  • Customs and excise verification of imported alcoholic beverages.

Frequently Asked Questions

How do I calibrate this alcohol refractometer?

The instrument is factory-calibrated using distilled water at 20°C. For field recalibration, place a few drops of distilled water on the prism, close the daylight plate, and use the included mini-screwdriver to adjust the calibration screw until the scale reads exactly 0%. Ensure the sample and instrument are within the 10°C to 30°C ATC range for accurate adjustment.

What types of beverages can this refractometer measure?

It is specifically designed for measuring the alcohol content by volume in clear, distilled spirits such as whiskey, vodka, gin, rum, tequila, and brandy. It is not suitable for beers, wines, or liqueurs containing high levels of dissolved sugars, as these will affect the refractive index and produce inaccurate alcohol readings.

Does the Automatic Temperature Compensation (ATC) require batteries?

No. The ATC mechanism is a passive, mechanical system within the optical assembly that automatically adjusts for temperature-induced changes in the refractive index. The entire instrument operates using ambient light and requires no batteries or external power source for its core measurement or compensation functions.

What is the resolution and accuracy of the measurement?

The scale has a minimum division of 1% alcohol by volume (v/v), which is the resolution for reading. The accuracy, referring to the precision of the refractive index measurement, is ±0.01. For best results, ensure the sample is homogenous, the prism is clean, and measurements are taken within the specified 10°C to 30°C temperature range.
