The DA 7250 NIR Analyzer analyzes samples in only 6 seconds, and can determine moisture, protein, fat, ash, starch and many other parameters with excellent accuracy. Available factory calibrations cover a wide variety of products and parameters and are built from our global database that encompasses hundreds of thousands of samples.

Features and Benefits

  • Easy to use - It's very easy to analyze a sample. In most cases just pour the sample into an open-faced dish, place it in the DA 7250 and it automatically starts the analysis. Results are presented on the large touchscreen.
  • Minimal sample preparation - Where other NIR instruments require that samples are ground or homogenized prior to analysis, the DA 7250 accurately analyzes samples as they are, minimizing the time from when you take the sample until you have the result. Grains, flakes, pellets, powders, pastes, slurries and liquids are all analyzed as they are without the need for expensive modules.
  • Accurate and rugged - The DA 7250 is based on diode array technology which is accurate, robust and proven. In diode array technology there are no moving parts and this makes the DA 7250 very suitable for challenging environments as it is not sensitive to vibrations or temperature. It is also IP65 certified which means it is dust and water-proof.

Operation and Handling

The DA 7250 was designed in cooperation with customers with the goal to create the most easily operated NIR instrument on the market. Not just because this makes work easier for operators, but because it matters for performance. The easier an analysis method is, the fewer mistakes you make, and the better your accuracy will be.

Three easy steps:

  • Pour the sample into the dish.
  • Select product from the list on the touch-screen.
  • Place the dish in the DA 7250.

Analysis starts automatically, and results are presented in large numbers after just a few seconds.

Remote Reporting and Administration

Our NetPlus software package makes analysis results available everywhere, and administration of groups of NIR instruments easier than ever before. NetPlus Reports is a web based reporting software which gives web based access to analysis results. Wherever you are you can always access updated analysis results. Monitor production, evaluate supplier performance, or verify product quality - on the fly!

NetPlus Remote is designed for remote administration of groups of instruments. Whether you manage just a few instruments or an NIR network of one hundred instruments, NetPlus Remote streamlines your tasks.

Sanitary Design Version

The DA 7250 SD is designed for placement in labs and production areas where sanitary designs are required. The sanitary design limits surfaces, crevices and other locations where food material could adhere. This makes it easy to clean, thereby reducing opportunities for microbial growth. Its stainless steel design and open analysis area makes it ideal for use anytime hygienic or cleaning requirements are high, such as in food production environments, in dusty or dirty conditions, or when samples are messy.


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.


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.

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.

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.
