Perten Aquamatic 5800 Portable Grain Moisture Meter


Perten Portable Grain Moisture Meter

The Perten Aquamatic 5800 Manual is a portable grain moisture meter designed for the larger farmer. Trials show accuracy to +/- 0.3%.

Product Description

Unique among portable moisture meters, the AM 5800 Manual Grain is based on the same high frequency 149 MHz technology and UGMA algorithm as officially approved meters. Drawing on the experience from more than 5,000 installed moisture meters, we have designed a battery operated, portable moisture meter benefiting from the accuracy, repeatability and reliability of the official meters.

The higher frequency signal provides greater penetration of samples and the UGMA (Unified Grain Moisture Algorithm) provides a more accurate result regardless of moisture level,
temperature or crop type. Together these make the AM 5800 Manual the most accurate and repeatable portable moisture meter available. It can analyze grains, oilseeds, pulses, beans,
lentils, seeds and more for moisture, Test Weight/Hectoliter Weight, and temperature.

Features and Benefits

Accurate: Thanks to high frequency 149 MHz technology and the UGMA algorithm you will get accurate readings, also on grain straight from the field or the dryer.

Easy to use: No sample weighing or volume measurement is required. Just pour the sample to fill the hopper and pull the handle to start the analysis. The AM 5800 Manual takes
care of the rest.

Repeatable: Excellent repeatability thanks to precision mechanics and advanced signal processing.

Rapid: In less than 20 seconds accurate readings for moisture, Test Weight and temperature are presented on the display.

Portable: Powered by 2 AA batteries and weighing only 5 kg / 9lb you easily bring the AM 5800 Manual to where you need it.

Smart interface: The touch screen with intuitive user interface makes the AM 5800 Manual simple to use. Input sample IDs, view results on a remote screen, and update through Bluetooth. The touchscreen uses resistance technology and will even respond to gloved hands.
