The Lab Depot offers Thermco Products, Inc Hydrometers which are manufactured, inspected and tested to exacting standards. The accuracy, uniformity, and dependability of each Hydrometer is assured due to individual testing procedures. Thermco is a leading supplier and manufacturer of temperature measurement and calibration instruments, and an ISO accredited provider of calibration. The calibration standards of each hydrometer are directly traceable to the National Institute of Standards and Technology (NIST) and DKD. The hydrometer we offer comes with a calibration report that includes a list of actual corrections to 1/10 of a division, accuracy for temperature or density correlated to NIST standards and a statement of traceablility to NIST standards.
The following scales are available:
Alcohol Hydrometers for alcohol, IRS, Proof, Tralle, Baume, Balling. These are used in breweries, wineries, and distilleries in measurements of alcohol levels.
Specific Gravity Hydrometers measure the relative density which is the ration of the mass of a solid or liquid to be a mass of an equal volume of distilled water. ASTM standard Specific Gravity Hydrometers.
API Hydrometers are used in petroleum products and they measure their standard API scale. We offer API Hydrometers with ASTM specifications and API Hydrometers with thermometers. Brix Hydrometers use a scale that is based on 1 degree Brix = 1 degree sucrose by weight at the specified temperature of 20 degrees C. The data of the National Bureau of Standards is used. Sodium Chloride Hydrometers measure saturation and concentration of sodium chloride. Calcium Hydrometers measure specific gravity and freezing point of calcium chloride.
Soil Analysis Hydrometers measure specific gravity and soil colloids in strict accordance to specifications of ASTM - American Society for Testing Materials.
