Hanna Instruments HI 83749 portable turbidity meter and bentonite monitor

Wines with low phenol contents, such as rosé, light reds and whites, should be checked for protein stability before bottling. Hanna Instruments offers a quick test to verify the risk of future protein haze formation: the HI 83749 portable turbidity meter and bentonite monitor.

If protein instability is detected, a subsequent test can help define the right amount of bentonite to be added for improving protein stability. It is important not to overdose bentonite to avoid stripping wine flavour, body and significant loss of colour, especially in young red wines. Moreover, adding only the necessary amount of bentonite to obtain the desired protein stability also saves costs.

The HI 83749 measures turbidity of samples from 0.00 to 1200 NTU (Nephelometric Turbidity Units) and is USEPA compliant. In the USEPA measurement mode the instrument rounds the readings to meet USEPA reporting requirements.
