Engler Viscometer WNE-1A | AELAB

Overview

Product Overview

The AELAB WNE-1A is an Engler Viscometer designed for Engler viscosity determination of petroleum products and bitumen.

The instrument is designed and made according to GB/T266 Petroleum Products – Determination of Engler Viscosity and T0622 Bitumen Engler Viscosity Determination (Engler Viscometer Method) in JTG E20-2011 Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering. The catalog also references Shanghai enterprise standard Q/YXYY11 WNE-1 Engler Viscometer.

The WNE-1A consists of the tester and a separate temperature controller. Both the inner and outer crucibles use stainless materials, and the inner crucible is specially processed to provide the smooth finish required for testing.

A digital-display temperature controller provides a temperature range of (0～100)℃ with ±0.2℃ temperature control accuracy. The specified standard water value is (51±1)s.
