Inquiry (采购产品): universal hydrometer Hello. I need to buy a hydrometer to measure the water content in rehydrated rabbitskin glue and glue size concentrations. According to an old reference book I am reading, they instruct to purchase a Baume Hydrometer to take this measurement...like it's the only type of hydrometer on the market. Could it be that this is a Universal Hydrometer that they are talking about? To make matters more frustrating, I cannot find the exact specific gravity of rabbitskin glue either(only as an addition in a gesso product. Bearing all this in mind, do you think the Universal Hydrometer will be the proper instrument to measure this material? Or do I still need to somewhere find the specific gravity of rsg? Many thanks for any insight you can provide, sincerely, Susan **** Hidden Message ***** Susan Card POBox 18071 Fountain Hills, AZ 85269 USA Company: See Art Gallery Phone: 480)816.8820 E-mail: me@susancard.com **** Hidden Message ***** me@susancard.com
