The Opti® hand-held digital refractometer allows you to analyse samples quickly and accurately.

Portable (fits in the palm of your hand), compact and simple to operate, the OPTi provides excellent 'on-the-spot' concentration analysis with automatic temperature correction. Accurate one button measurement and a clear display presents reliable results.

Software:

  • Quick 2 second read time of sample
  • Onboard library of over 40 scales (including Oechsle, Brix, Wort SG, Alcohol Probable* & more)
  • Up to 3 active scales on a single device
  • High Ambient Light (HAL) detection warns of too much light entering the sensor
  • Unique AG Test Mode that allows the use of long-life non sucrose based certified reference materials
  • Programmable read delay for sample temperature stabilisation

(*) NB Alcohol by volume is measured by way of the Zeiss scale and hydrometer (not included) - see Application

Hardware:

  • Clear digital LCD display
  • Ergonomic & durable handheld design
  • East-clean, stainless steel prism dish
  • Rapid temperature stabilisation

NB Alcohol Determination: Other products for determinining probable alcohol are available, including a Refractometer (see Eclipse Alcohol Determination Refractomer - part code 94222) and an Ebulliometer (traditional version) - part code 94231.

 

Please see the Test Equipment category in Catalogue for our full range of test equipment.

 

Application

  • Fruits & Honies: Used for testing the ripeness of fresh fruits such as grapes and tomatoes simply by squeezing a small amount of juice directly onto the refractometer prism. OPTi refractometers are used in the manufacturing of jam, marmalade, syrup and other high sugar content products as well as quickly testing for moisture in honey direct at the hive. They are ideal for testing finished juices and other soft drinks. Scales include: Brix, °Butyro, HFCS, Salinity, Water in Honey, and more - see image chart
  • Beer: In breweries refractometers are used to measure Wort prior to fermentation as well as determining alcohol content*.
  • Wine: In vineyards, grape ripeness can be checked before harvest, sugar content assessed, and ABV content (measured by way of the Zeiss scale and hydrometer) in the final stages of production*. Scales include: Brix, Wort SG, °Baume, Alcohol Probable, Oechsle - see image chart. Before you use the refractometer, you will need to measure the Specific Gravity of your product via a hydrometer (see link below).

(*) Determining alcohol by volume (ABV): Before you use the refractometer, you will need to measure the Specific Gravity of your product via a hydrometer (not included). The alcohol content is determined by a calculation involving the refractometer reading and the Specific Gravity reading. Enter the readings into the online calculator to give you the alcohol content, or do the calculation yourself and look up the resulting value in the table supplied to get the alcohol content.

Features

  • Capable of giving you over 10,000 readings on just 2xAAA batteries.
  • Comes with 3 interchangeable scales pre-loaded from an onboard library of over 40 individual scales (see image chart) - meaning there are over 9880 possible OPTi scale choice combinations
  • Scales include Brix (0-95), Refractive Index, Alcohol Probable, Oechsle, °Baumé, °Butyro, Colostrum Quality, Wort SG, Ethylene Glycol %, HFCS, Salinity, Water in Honey, etc., and many more can be swapped and selected at any time
  • Need Brix for one application, and Alcohol Probable for the next? No problem. Switching scales only takes a moment, and with a read time of 2 seconds per sample, the OPTi is one of the quickest and most convenient ways to monitor and control your concentration on-the-go - see YouTube tab for video
  • Durable design and vast range of scales, so is suitable for a wide range of applications; from the clinical laboratory to the harshest of environments
  • Includes a stainless steel prism dish which rapidly stabilises sample temperature
  • Supplied with protective case
  • Durable IP65 rated body
  • Manufactured in the UK
