Bitumen Flash and Fire Point Tester Cleveland Open Cup

Automatic Cleveland open cup apparatus with gas or electric heater to determine flash and fire points of bitumen and petroleum products. Used for safety and grade verification in refineries and asphalt plants.

Specification

A brass test cup of bitumen is heated at a controlled rate while a small test flame is passed across the cup at set temperature intervals. The lowest temperature at which vapours ignite gives the flash point, and the fire point follows. The tester helps determine safe handling temperatures for bitumen.

Features

• Automatic test flame application with swing arm
• Electric heater with linear heating rate
• Digital temperature display with PT100 sensor
• Flash detection thermocouple option
• Windshield for draught protection
