DSHD-261 Manual Pensky-Martens Closed Cup Flash Point Tester ASTM D93
Product Description
DSHD-261 Manual Pensky-Martens Closed Cup Flash Point Tester ASTM D93
Summary
The DSHD-261 Manual Pensky-Martens Closed Cup Flash Point Tester is designed and manufactured according to GB/T 261-2021 and ASTM D93. It determines the closed cup flash point of petroleum products. As a manual model, heating power is continuously adjustable from 0 to 600W and shown visually by voltmeter, with heating mode adjusted manually. Stirring is mechanical drive, meeting Procedure A/C (90–120 rpm) and Procedure B (250±10 rpm) requirements. The silicon carbide furnace body and stainless-steel table board make the structure small, exquisite, and easy to clean. It comes with mercury-in-glass thermometers in three ranges: -5–110°C (0.5°C division), 20–150°C (1°C division), and 90–370°C (2°C division). The oil cup has an inner diameter of 50.7–50.8mm, depth of 55.7–56.0mm, and approximately 70ml capacity. Ignition source is gas or other civilian fuels. This manual model is the most economical choice, suitable for low-volume or occasional testing where full automation is not required. For higher throughput, semi-automatic model DSHD-261-1 and fully automatic model DSHD-261D are also available.
