[RE-wrenches] Fwd: Hydrometer source

[John McNicholas - Key Power Services]

We have been using a digital unit for a few years - Sper Scientific 300055 Pocket Digital Refractometer - expensive ($300+), but it appears to be very accurate..... has built-in temperature compensation.

Hi Dave,
 
We use and recommend NAPA 700-1145.  $12.00  I am starting to look at digital Refractometers. Any recommendations?

We used to buy temperature compensated hydrometers from AEE to include with the sale of a battery bank for off grid customers. My sales person says AEE is no longer carrying that item. I believe they were made by Dekka.
 
Recommendations for a new source for battery hydrometers in the $8 to $ 15 range?
