JETVISC™ is the first dedicated viscometer for testing aviation fuel (jet fuel) at sub-zero temperatures. Aviation fuel conforms to the specifications in ASTM D1655 and DEF STAN 91:91.  The chosen method for kinematic viscosity is ASTM D445. JETVISC™ complies fully with ASTM D445. In summary, JETVISC™ is a self contained, fully automated, kinematic viscometer for testing aviation fuel at minus twenty degrees Celsius.

Established in 1850 Poulten Selfe & Lee have established a worldwide reputation for capillary viscosity measurement. The PSL Calibration Laboratory is accredited by UKAS to ISO 17025 for the calibration of glass capillary viscometer tubes and viscosity standards. All PSL viscometer tubes are manufactured and calibrated in the United Kingdom by PSL. In addition PSL manufactures the RHEOTEK range of automated viscometers, a dedicated range of instruments which are designed to measure viscosity of a range of substances including polymers, ink, bitumen, oil and fuels. The JETVISC was developed as a dedicated analyser for measuring the kinematic viscosity of aviation fuel at -20 deg.Celsius.
