API Scale Thermo-Hydrometers
API Scale Thermo-Hydrometers
All of the below thermo-hydrometers are available with a NIST traceable, ISO/IEC 17025 accredited report of calibration. When ordering, please add the suffix -C to the catalog number. Please fee free to contact a customer service associate with questions.
ASTM API THERMO-HYDROMETERS
These hydrometers are fabricated with a thermometer in the lower body for convenience to the user. For any particular API gravity range, three temperature ranges are available, coded as follows: L=Low 0/150oF, M=Medium 30/180oF, H=High 60/220oF. The units listed below are the most popular. Variations are available on special request.
