El refraktometreler

LLG-uniREFRACTO 5 pro is a compact digital 3-scale handheld refractometer for measuring, e.g. Brix and refractive index of liquids. Two scales are pre-set to 0 - 95 % Brix and 1.33 - 1.54 RI, the third scale can be freely selected from more than 45 different scales, including Brix, refractive index, AdBlue^®, °Baume, °Butyro, Ethylene Glycol %, Calcium Chloride % and specific gravity. All three scales can be freely selected and changed. The operation is quick and easy, calibration can simply be done with distilled water. The waterproof housing (IP 65) allows cleaning under running water.

• Easy switching between the three scales
• 4-digit LCD display
• Automatic temperature correction
• Sample plate made of stainless steel

Simple and precise optical instruments to analyse liquids and their solid contents. Models are equipped with an automatic temperature compensation device (ATC). Supplied with a plastic box and comfortable leather-type case.

For measurement of various high concentration samples such as jam, marmalade, jelly, honey, concentrated juice or acidity and salinity. Ingress Protection class IP 65 means that they can be cleaned under running water. Easily calibrated since "zero-setting" (calibration) is achieved using water. Temperature measurement with Automatic Temperature Compensation. Various models for a variety of applications, e.g. measurement of urine, salt, sugar. With data transmission via near field communication (NFC).

Type PR-32α
Can be used to measure fruit juices, soft drinks, diluted soluble oils, aqueous cleaning solutions, etc.
Type PR-101α
Applications include measuring fruit juices, lemonade, coffee, diluted soluble oils and anti-freeze solutions.
Type PR-201α
It can be used for accurately measuring jams, concetrated fruit juices, coolants and similar products.
Type PR-301α
Especially suited to measuring jellies, liquid cane sugar,etc.
Type PET-109
This model is used for simply determining the concentration of ethyl alcohol, which is used in foods and for cleaning, cooling and other purposes.
Type PR-RI
A new Refractive Index model has been added to the popular long-selling "Palette Series". It is suitable for measuring the refractive indices of liquid samples in pharmaceutical and chemical products. Ambient temperature: 10 to 40°C.

All models are with data transmission via near field communication (NFC).

Digital hand-held refractometer with two different scales, Brix and RI.
Handling is fast and very easy, distilled water is used for calibration. With automatic temperature compensation.

DR301-95 offers 2 additional user-defined scales and can be connected to a computer. Specialities: optional temperature compensation feature and upper and lower tolerance alarm.

The PEN-PRO has a measurement range of Brix 0.0 to 85.0 % and a temperature range of 10 to 100 °C which can be used to measure almost any sample. The PEN-PRO measures continuously while you stir your sample, so you can watch the reading stabilize as the temperature evens out. No need to take several measurements of the same sample. Fully digital. The PEN-PRO is ideal for food factories (fruit juice, coffee, soft drinks, soy sauce, sauces, seasoning, soup, concentration jam, marmalade, jelly and syrup, etc).

• Just dip into or touch sample surface
• Easy and quick measuring in just 3 seconds
• Hot or cold samples can be measured
• ATC measurements are shown as if measured at 20 °C
• Zero setting (calibration) can be done with distilled or tap water
• Class IP65: Dust-tight and protected against water jets. Rinse clean under running water

Digital display of the automatically temperature-compensated result. Battery powered, splashproof. For measuring the density of urine.

The WM-7 is a digital pocket wine refractometer with 7 scales, developed for the simple, rapid and precise measurement of grape must.
Measuring ranges: Brix, T.A., Oe, KMW, Baum

Precision instruments for quick daily use. Various scales and functions ensure there is a suitable refractometer for every application area.

Portable device for determining refractive index and derived concentration values. Simple operation and fast results: the sample is either dripped onto the measuring cell or the instrument is immersed directly in the sample liquid. Suitable for laboratory and field measurements, e.g. in food processing or industry.

• Automatic temperature compensation
• Suitable for measurement of dark samples
• Backlit LCD display shows values and menu functions
• Calibration with water
• Memory for up to 1100 measured values, together with sample ID, unit, temperature compensation coefficient, time and date
• Individual formulas for calculation of user-defined concentration data can be defined in the device
• Measuring units: nD, nD temperature compensated, Brix% temperature compensated, HFCS42, HFCS55, °Baumé, °Oechsle (D, CH), °KMW (Babo), T.A. 1990, weight %, vol.-%, specific weight and freezing point (in °C or °F) for ethanol and NaCl, weight %, volume % and freezing point (in °C or °F) for ethylene glycol and propylene glycol, weight % and volume % for isopropyl alcohol, user-defined unit
• Values can be transferred to the PC via IR interface

For simple, manual measurement of concentrations and refractive indices of liquids. Hand-held, precision refractometers with focussing eyepiece, soft rubber eyecups (to reduce straylight ingress, also spectacle lenses do not slip off and are not scratched), case and conversion tables. Hand-held refractometers cannot be fitted with a thermostatic controller and so measurements have to be temperature compensated.

Models with extra code M: Basic model
Models with extra code T: with automatic temperature compensation (ATC)
Models with extra code α: with automatic temperature compensation (ATC) and protection class IP65
Models with extra code H: for hot samples, with prism made of tempered glass

Versatile, maintenance-free handheld refractometers in a handy and robust design.

• Several selectable scales
• Eyepiece can be adjusted to different visual capacities
• With automatic temperature compensation (selected models only)
