I. Overview

Flash point: under the specified test conditions, when testing with the specified method, the vapor of the test sample can be ignited instantaneously by using the test flame, and the flame spreads to the entire liquid surface, and is corrected to the lowest temperature of the test sample under 1013kPa atmospheric pressure.

Principle of Closed Flash Point Detection by Low Temperature Balance Method：Inject the specified volume of test sample into the test cup maintained at the expected flash point temperature of the tested material. After the specified time, ignite and observe whether flash occurs at different temperature points. Continue the test with the newly taken sample until the flash point is measured and the specified sensitivity is reached.

HZBS-3D Low temperature closed flash point tester by balance method is manufactured under the ASTM D3828 standard.

This instrument takes advanced electronic temperature control instrument as the core, and is equipped with appropriate interface circuit to realize the automation of temperature control. It has the functions of automatic switching of heating power, automatic temperature control, etc. This instrument is simple in operation, reasonable in structure, accurate in detection, stable in performance, and intuitionistic in display. It is an ideal substitute for imported instruments and can meet the requirements of petroleum, chemical, paint, railway, aviation, electric power, commodity inspection and scientific research institutions for rapid testing of closed flash point of petroleum products.

This instrument is especially suitable for testing the flash point of closed cup of various paints, paints, adhesives, solvents, petroleum and related products with the flash point within the range of - 30 ℃~+100 ℃.
