The Perten DA 7440 is a versatile NIR sensor, designed to provide real-time measurements to support quality monitoring and process control.

Continuous monitoring is essential in food production, and above line NIR analysis measures several important product parameters simultaneously.

Testing has never been more crucial to the food industry, and this instrument is a time-saving, adaptable means for doing it.

Use the Perten DA 7440 to test for:

• Moisture

• Salinity

• Fat

on these products:

• Snack foods

• Other food products, such as potatoes and pasta

• Tobacco

Why choose the Perten DA 7440?

The DA 7440 provides continuous measurement for automatic or manual process control, and to optimise moisture and fat content in a broad range of foods.

It provides results in real time, using web-based software and wireless communication. Its connectivity is industry standard, enabling it to integrate with existing systems.

The instrument is pre-calibrated for a wide range of snack foods.

It has easy to use touchscreen controls and display, and is designed to be durable with minimum maintenance.

Its high-speed diode technology allows users to track process changes accurately, and with its full-spectrum calibrations, it requires hardly any adjustment when substituting products or starting up.

How does it work?

The Perten DA 7440 uses near infrared analysis (NIR) for food testing.

This spectroscopic technique can analyse food rapidly and produce data in seconds.

Using infrared light, it can measure certain organic compounds essential to, and occurring in, foodstuffs.

These compounds include fat, protein, starch and sugar.

Typically, NIR will have an accuracy that is 1.5 times the variability of its reference method, based on calibration.

It is an established, effective way of testing and the technology driving it has become more refined.

The DA 7440 uses Perten’s dedicated Process Plus software, designed to meet the requirements of the process industry. It provides advanced functionality based on a modern communication infrastructure.

This makes its data readable across networks, on any web browser, offering multi-user capability. It can be easily integrated into SCADA data analysis systems.

To do this, it does not require installing any additional software on users’ devices.

What are the benefits of above line NIR analysis?

Using the Perten DA 7440, you can measure and control moisture and other content in the processing of a range of foods.

This is an efficient and rapid real-time measurement method that can optimise production processes which is easily installed over conveyor belts.

You can also integrate its results into existing automated systems.

With its diode array technology the DA 7440 will give stable, accurate readings even when products change on the line.

Its measurement parameters include moisture, fat, fibre, salt and spices, protein, sugars and nicotine.

Fast, accurate food testing

Confidence in food quality is essential for producers, suppliers, retailers and consumers.

Fast, accurate food testing helps identify additives and ingredients, detect food fraud and optimise production processes.
