TBTWNE-1A is referring to ASTM D1665 Standard Test Method for Engler Specific Viscosity of Tar Products.
1.It adopts digital temperature controller, offering intuitive and convenient parameter settings without complex operations; high temperature control accuracy, with errors controllable within ±0.2℃, meeting the stringent temperature stability requirements of viscosity testing;
2. Inner and outer pots have dimensional precision; made of 304 stainless steel for good corrosion resistance and oxidation resistance, it is not prone to rust or damage even after prolonged contact with the test liquid;
3. The Engler pen is made of copper with moderate hardness, wear resistance, and strong deformation resistance, ensuring a long service life and stable, long-term use for timing operations in viscosity testing.
