HWP22-10S Solid Spontaneous Combustion Point Tester Introduction
The HWP22-10S solid auto-ignition point tester determines the auto-ignition characteristics of solid matter by placing the solid matter in a 20mm cube steel wire mesh at an elevated temperature in a heating chamber. Comply with GB / T21756-2008 "Determination of Relative Spontaneous Combustion Temperature of Solid Substances of Chemical Products for Industrial Use", ECtestA16 and NFT20-036 and other standards. Features
1) Embedded processor, Windows CE operating system;
2) 8-inch LCD touch screen, which can display test status in real time;
3) Support "standard mode" and "custom mode" (including the support of saving exothermic peaks during custom experiments), taking into account the standard and flexibility of the test
4) Combining high temperature insulation technology, temperature control and precision detection technology;
5) Use electric heating crucible furnace, natural convection in air circulation to ensure the sample is evenly heated;
6) The furnace cavity material is made of heat-insulating vacuum ceramic fiber, which has good heat insulation effect;
7) The cubic steel wire net is suspended at the bottom of the furnace cover, and the operation is safe and convenient when placing samples;
8) Realize automatic heating control, temperature control and combustion detection;
9) Equipped with a stern rod for cleaning the small hole in the center of the liner;
10) Equipped with a crumb tray to collect the specimens dropped from the cage and the residual specimens cleaned from the stern rod;
11) Equipped with a cooling bracket for placing the furnace cover assembly on it for cooling after the test;
12) Use thermocouple sensor to respond quickly and accurately to temperature changes;
13) Real-time display of time and temperature curve graph, you can view the original data;
14) The test process is fully automated without manual intervention, and supports parameter setting, data storage, and viewing reports. Technical Parameters
