The TESTech solid auto-ignition point tester is designed according to GB/T 21756-2008 Determination of Relative Auto-Ignition

Temperature of Solid Substances, with reference to GB/T 21860-2008 Test Method for Auto-Ignition Temperature of Liquid Chemicals.

It is a method for determining the auto-ignition behavior of solid chemicals by programmed heating and is suitable for most solid specimens.

A solid sample of specified volume is placed into the oven. The oven temperature is increased at a rate of 0.5 C until 400 C.

The specimen temperature and oven temperature are measured simultaneously. When the specimen self-heating temperature suddenly reaches 400 C, the equipment determines that auto-ignition has occurred and automatically records the oven temperature at that moment.

This recorded oven temperature is taken as the auto-ignition temperature of the specimen.

• Two thermocouples are provided.
• One thermocouple is inserted into the center of the specimen to measure specimen temperature.
• The other thermocouple is placed between the specimen and the heating furnace to monitor the furnace temperature.

• The specimen is normally placed in a stainless steel mesh basket with a cubic side length of 20 mm, and the basket is then placed in the heating furnace.
• Because a thermocouple must be inserted into the center of the specimen during testing, the solid specimen should normally allow insertion of a 1 mm thermocouple.
• If the specimen cannot accept a thermocouple or is too large to fit into the 20 mm cubic mesh basket, it should be crushed or ground before testing.

• Explosive products.
• Products that self-ignite in air at room temperature.
• Solid products that melt under the conditions of this method, such as surfactants.

• Determines the auto-ignition characteristics of solid substances by placing them in a steel wire mesh cube with side length 20 mm under rising temperature conditions in the heating chamber.
• Conforms to GB/T 21756-2008 Determination of Relative Auto-Ignition Temperature of Solid Substances for Industrial Chemical Products.

• Embedded processor with Windows CE operating system.
• 8-inch LCD touch screen for real-time display of test status.
• Supports both Standard Mode and Custom Mode to combine standardization and flexibility.
• Integrates high-temperature thermal insulation, temperature control, and precision measurement technology.
• Uses an electrically heated crucible furnace with natural convection air circulation to ensure uniform heating of the specimen.
• Furnace chamber is made of insulated vacuum ceramic fiber with strong thermal insulation performance.
• The cubic wire mesh basket is suspended at the bottom of the furnace lid for safe and convenient specimen loading.
• Provides automatic heating control, temperature control, and combustion detection.
• Equipped with a cleaning rod for clearing the small center hole of the inner liner.
• Equipped with a debris tray to collect specimen fragments falling from the basket and residues removed by the cleaning rod.
• Equipped with a cooling stand for placing the furnace lid assembly after the test for cooling.
• Uses thermocouple sensors for fast and accurate response to temperature changes.
• Displays real-time time-temperature curves and allows viewing of raw data.
• The entire test process is fully automated, with support for parameter setting, data storage, and report viewing.
