Non-destructive, Dry Matter (DM) / Brix monitoring for fruit!

The SUNFOREST H-100 series is a range of field portable NIR spectrometer that can non-destructively measure internal quality of fruits such as Brix, Dry Matter, Moisture, Browning, etc.

The H-100 series can be widely used from orchard to fresh market as a useful tool determining produce quality at every application. It could provide very simple and rapid bulk testing, helping growers to determine when to harvest on orchard and also allowing supply chains to carry out import inspections.

Trusted by thousands of clients in the fruit industry, the SUNFOREST H-100C has proven to be a reliable instrument for determining and tracking fruit quality metrics.  It can detect fruit quality in up to 10 varieties and types of fruits.

A demonstration model* is included for the fruit that you select.  A bias correction can be made by comparing the nondestructive prediction to the actual value of the juicing refractometer.  If desired, models can be upgraded to your exact fruit variety.  Perform comparative tests with the H-100F to destructive measurements, then send this to us and a new model will be built for you.  Then download this to your meter for better accuracy. 

GPS Application (by option): The H-100C is compatible with GPS application to show a travel line on orchard map and indicates DM and Brix dots along the path of samplings.
