Quickest Lead Times in the Industry for Hydrometer Calibrations

Our environmentally-controlled laboratory houses extremely accurate standards for all brands of viscometers using only ISO Guide 25 accredited standard reference materials. Your viscometer will be tested at 25 degrees Celsius using the spindles of your choice with as-found and as-left data provided.

Hydrometers are tested according to your instructions or manufacturer’s recommendations. InnoCal is the only authorized calibration lab in the United States for ERTCO hydrometers. We test all types including Baume, Alcohol, API, ASTM, Brix, Sodium Chloride, Balling (Plato), Calcium Chloride, and Liquid Petroleum Gas hydrometers. We will also check the thermometer on your hydrometer, if applicable. Our fully-equipped hydrometers calibration lab has the quickest lead times in the industry—3 to 5 days without expediting!

Innocal’s partnership with Cole-Parmer allows you to purchase your equipment pre-calibrated and delivered to your facility with our certificate. This removes the expense, time, and hassle of sending it out to a lab for calibration. Your hydrometer or viscometer arrives with the NIST-traceable certificate and is ready to put into use immediately. Get a quote from InnoCal today.
