ASTM D3829 Automatic Engine Oil Viscosity Tester Boundary Pumping Temperature SH416

## SH416 Automatic Engine Oil Borderline Pumping Temperature Tester (ASTM D3829 Compliant)

The SH416 Automatic Engine Oil Borderline Pumping Temperature Tester is developed and manufactured in accordance with Chinese national standard **GB/T 9171‑1988 Method for Measuring Borderline Pumping Temperature of Engine Oils** and petrochemical industry standard SH/T 0562. It also complies with ASTM D3829 and ASTM D4684 standards.

This instrument is used to determine the borderline pumping temperature, low‑temperature yield stress and apparent viscosity of automotive engine oils. It features a broad test temperature range from ‑5 °C to ‑40 °C.

**Alternative product names:**
‑ ASTM D3829 Critical Pumping Temperature Tester with Mini‑Rotary Viscometer
‑ ASTM D3829 Borderline Pumping Temperature Tester with Mini‑Rotary Viscometer
