ethyleneglicol-propyleneglycol concentration detectors

[davidlleida]

Hi,
I would be grateful if someone could provide with some references for manufacturers of ethyleneglycol and propylenglycol concentration detectors %.
It's for a project of industrial cooling in a fruit juice industry

Thank you so much

Thank you all,
but in fact, I'm not interested in a tool that I have to check myself the concentration of secondary system.
I'm lookin for an analyser that installed in the system gives me an Input to my PLC controller in order to have an alarm message.
I know there is a provider that actually I can't remember but I would like to have more options.

I'll give the link when I have it

The instrument which will give a signal to PLC called Inline Refractometer and manufacture by:
Misco, Schmidt+Haensch, Maselli, Cole -Parmer. They are not cheep.

A conductivity sensor could be an option.

... without any need to measure concentration all the time ... check this...

"Product durability
In a sealed container or in a closed system the properties of Temper remain stable, and its durability is unlimited.

Safety
Temper is neither inflammable nor explosive. Temper is less hazardous to health than traditional cooling mediums and does not degrade compared to glycols. It can quite simply be diluted (50% water) and poured down the drainage. Always consult the local sewage work before pouring out large volumes. Temper does not require any special handling or storage measures. The product is suitable to use as a heat transfer medium according to The Swedish National Food Administration"



Best regards, Josip :)
