Anywhere – Rugged IP65 certified design for use at-line or in the lab

Anytime – Never wait to get results, 6-second analysis without sample preparation

Anybody – Trained chemists or factory staff, everyone will confidently use the DA 7250™

Key features – DA 7250™ NIR analyzer

The DA 7250™ gives you faster and more accurate results, and makes analysis easier than ever before.

6-second analysis

The DA 7250™ analyzes a sample in only 6 seconds. Its rapid analysis and minimal requirement for cleaning between samples give the DA 7250™ an analysis capacity which is 4-5 times higher other NIR instruments.

No grinding or homogenization of samples

Thanks to its large light spot and real-time analysis of a rotating sample, the DA 7250™ analyses a much more representative sample than other instruments do, and can accurately analyze inhomogeneous samples as they are.

Lab and At-line use

The DA 7250™ is built for challenging environments.

  • Its IP65 certification means it is dust and water proof
  • Diode array technology uses no moving parts in the optics and is unaffected by vibrations
  • The spectrometer is temperature stabilized and provides accurate results from 5-40C

Stand-alone instrument

The DA 7250™ is a stand-alone instrument and does not require an external computer. External computers often experience communication issues with instruments, and can’t be placed in the dusty or dirty environments that the DA 7250™ excels in.

Factory normalization

All instruments are normalized at factory, in an advanced procedure where the wavelength scale and absorbance scale are standardized to make individual units identical to each other.

Automatic self-tests

The DA 7250™ automatically performs several self-tests and diagnostics to ensure that it always performs optimally. The wavelength scale is confirmed using a built-in Xenon lamp which emits light at 7 exact wavelengths, and the absorbance scale is checked using a Teflon-coated ceramic reference flag. As the DA 7250™ is so rapid, self-tests can be performed before each analysis, making the DA 7250™ a more stable analyzer than other NIR instruments.

Easy to use

The straight-forward sample handling and the intuitive user interface mean that anybody can operate the DA 7250™ confidently, and get accurate results. Find out more about the easy operation of the DA 7250™ here, in text, photos and video.

Large touch screen

The large touch screen lets operators clearly see results even from a distance, and makes it very easy to operate the DA 7250™. The screen is rugged and is designed to be used also in process environments.

Feature rich software

While the user interface is intuitive and easy to use, it also incorporates a number of powerful features such as report generation, result display options and data integration with other applications.

Plug & Play devices

Windows-enabled USB devices such as memory sticks, barcode scanners, printers are supported by the DA 7250™. Unlike other manufacturers we don’t limit you in your choice of devices. Just plug your device in and start using it.

Data connectivity

Analysis results are often needed somewhere else than where the instrument is placed. The DA 7250™ can export data in a multitude of formats, and can be configured to automatically exchange data with other applications.

Web Reporting

Using our optional Web Reporting feature results from one or several instruments can be accessed from anywhere, through a web browser. There are many potential uses: a purchasing manager can pull out reports on incoming materials; a production manager can track key process parameters over time; a lab manager can monitor NIR performance vs reference methods. Several report templates are available, and results are shown in tables as well as graphs.

Same platform as On-line

Diode array is the only NIR technology which is suitable both for benchtop analysis and process analysis. Our on-line and in-line NIR instruments use the same platform as the DA 7250™, which means seamless transfer of calibrations.

ISO 12099 compliant

The DA 7250™ supports the procedures described in the ISO standard 12099 on the development and validation of NIR calibrations, and is completely compliant with the standard.

Applications – DA 7250™ NIR instrument

The characteristics of the DA 7250™ NIR analyzer make it ideal for a wide range of applications.  Grains, pellets, pastes, powders and liquids are all analyzed in only 6 seconds.

Below are examples of applications the DA 7250™ NIR analyzer is used in.

Feed milling

Use the DA 7250™ NIR instrument to analyze ingredients, in-process samples and finished feeds for parameters such as moisture, protein, fat, starch, energy, fibers and amino acids – all without having to grind samples.

  • Verify incoming ingredients against specifications
  • Get true nutritional values for ingredients, and improve formulations
  • Optimize fat, protein and moisture in your process and save money

Oilseed processing

With the DA 7250™ NIR instrument you can analyze for moisture, oil, fatty acids, protein and other parameters in oilseeds, meals and oil. No grinding is required for oilseed analysis, not even for sunflower seeds.

  • Test seeds at intake to pay the right price
  • Analyze meal to optimize extraction, drying and blending
  • Determine FFA, phosphorous and more in oil

Flour milling

The DA 7250™ NIR instrument lets you analyze wheat and flour for moisture, protein, ash and more. It provides top accuracy in a rugged, IP65 rated housing. Place it anywhere in the mill for immediate analysis results.

  • Test wheat at intake and during tempering
  • Optimize ash content with rapid and accurate analysis
  • Analyze co-products such as bran or middlings

Petfood production

Whether you produce wet or dry petfood, the DA 7250™ NIR instrument will analyze ingredients as well as finished petfood for moisture, protein, fat and more. Little or no sample preparation required, minimal cleaning between samples.

  • Analyze nutritional value of ingredients
  • Optimize production
  • Verify end-product quality

Seed breeding

The accuracy and speed of analysis make the DA 7250™ ideal for seed breeding companies and institutes. Analyze any type of grain or oilseed for standard parameters such as moisture, protein and oil, and specialized traits such as fatty acid profile or amino acid levels. Thousands of samples can be analyzed in a very short time, and any size sample can be analyzed – from just a few grains to 500 ml. Several of the leading institutes and companies worldwide use the DA 7250™.

Ethanol production

Many ethanol producers have been able to increase output and lower costs thanks to the DA 7250™ NIR instrument. Raw materials, fermentation samples and by-products are all analyzed in just a few seconds. Instead of waiting half an hour for HPLC results you can get an instant analysis of HPLC parameters in fermentation samples.


Analyze cheese, butter, milk, cream and powders with no sample preparation and no clean-up after analysis in the DA 7250™ NIR instrument. Using the disposable cup system, the sample is simply placed in a plastic cup which is disposed of after analysis. This makes the DA 7250™ extremely rapid and easy to use. Its accuracy makes it possible for you to control production to very tight limits.

Other Food

The unique sample presentation and the speed of analysis make the application possibilities nearly limitless. Snackfoods, potato products, breakfast cereals and meat products are just a few analysis examples where the abilities of the DA 7250™ NIR instrument bring great benefits.

Starch production

The flexible sample presentation of the DA 7250™ makes it possible to analyze both the raw materials and nearly all in-process products as well as end-products. Grains, slurries, liquids and powders – all are easily analyzed in the DA 7250™ NIR instrument.
