    Digital refractometer?

    Anybody ever use one? I'm looking for one that can do both Ethelene and propolene glycol. I would need % volume and freeze point. We look after lots of stores that use glycol loops for the MT and RTUs. Looking to get accurate (+ or -) 1% readings.

    Thank you,
    Eddie

    I just use the spyglass type, never let me down and no batteries...

    If I had to buy one I would probably go with a Brix...They use Brix on the Methane generation plants I work at and they seem really user friendly and robust...

    They use two different ones, one for electrolytes and one for freeze protection.
    If a day goes by and you have learned nothing, I hope you got a lot of sleep.

    I use a brix refractometer (spyglass type). That is all you need.

    Misco Palm Abbe

    Check out Misco Palm Abbe. Have used one for ethylene glycol and compared to hydrometer readings. Hasn't let me down yet. I actually prefer them due to the fact that anyone can use them and doesn't have to know anything about specific gravity and temperature compensation. At the same time it is very fast and is helpful when trying to dial in glycol/water persentages. Not sure if one unit will do both Propylene/Ethylen Glycol. Contact Misco or take a look at their website for more info.

    The MISCO PA-203X model can be ordered with both PG & EG scales in freeze point and percent concentration. company is out of ohio 216-831-1000 with friendly customer service folks.
