REFRACTOMETERS :

           digital ( or numerical ) type 

           precision 1 gramme 

           just a drop of must or wine on the saphyr window and you get the result in brix or in probable  alcohol rate in 5 seconds

           automatic temperature correction

OPTICAL DISOLVED OXYGEN SENSORS :

 

the LDO from Hach lange the most famous in wine industry , maintenance free , sensor membrane change not before 2 years ( 3 months with electrochemical type )

Connected on the interface HQ30D ( one canal for 4 available sensors , such as conductiviy ,ph )

DENSITY METER  :

densiter can be measured with different method :

one of the most precised is the vibrating U tube which measures oscillation frequency of a  tube with U shape filled with liquid .

Frequency is directly dependant on liquid mass 

example :   DMA 35 from Anton Paar ( price around 1600 $ ) resolution 0.0001g/cm( or 0.1g/liter )

 

 

 

 

 

DISOLVED CO2 SENSORS :

     not yet in production ( 1 patent )

     could be manufactured if strong demand ( more than 1000 parts ) 

     price target : 600 euros for 20 mg/liter precision
