KV-2 Low Temperature Viscometer Bath 94710-4

Product catalog summary

Overview: The KV-2 Low Temperature Viscometer Bath 94710-4 is designed for measuring the kinematic viscosity of petroleum products, chemicals, and solvents, particularly under low temperature conditions. It adheres to standards such as ASTM D445-IP 71, ASTM D446, ISO 3104, and ISO 3105.

Specifications: The viscometer operates within a temperature range of -40 to +20 °C, with a temperature stability of ±0.01 °C. It can accommodate up to two standard viscometer tubes and has a bath capacity of 7 liters. The device uses anhydrous methanol or denatured ethyl alcohol as bath fluid and is powered by a 220/240V, 50/60Hz, 2.7 kW system.

Design and Features: The KV-2 features an extra narrow footprint of 37 cm width, optimizing bench space. It includes a heated top plate and viewing window to prevent condensation and ice formation. The integral refrigeration system can reach -40 °C in less than 4 hours. The bath is equipped with an independent over-temperature and low fluid level cut-out, along with a warning alarm for safety.

Data Logging and Calibration: The viscometer allows data logging via an external RS-232 port when connected to a PC. Each unit comes with a calibration certificate traceable to national standards, with a nominal calibration point at -20 °C. Customers can request specific temperature calibrations.

Stability and Performance: Stability graphs indicate the device maintains temperature stability within ASTM limits (±0.05 °C) at both -40 °C and -20 °C. The illuminated bath ensures clear visibility, and the insulation along with the heated viewing window prevents condensation.

KV-2 Low Temperature Viscometer Bath 94710-4-2

Low Temperature Kinematic Viscosity Aviation fuel, lubricants and hydraulic fluids are exposed to extreme temperatures, both high and low due to the range of altitudes aircraft fly. In particular it is essential that jet fuel maintains the ability to flow freely throughout the aircrafts fuel system, aiding the fuel flow to the engines. The spray pattern at the injector nozzle in jet engines is known to be affected by the viscosity. For aviation fuel, lubricants and hydraulic fluids kinematic viscosity is a key performance property. For aviation turbine fuel (AVTUR), such as Jet A1, the kinematic...
