Needle flame combustion tester
The touch screen control needle flame combustion testing machine is developed according to the requirements of standard gb4706.1-2005 and GB5169.5 "test flame needle flame test method device, confirmation test method and rules" on needle flame combustion test, and fully meets the national standards and the relevant UL, IEC standards of the new comprehensive equipment.In addition to the originality of the device itself with large functions, the device adopts full-color seven-inch touch operation display screen, which makes the test easy and efficient.At the same time, the horizontal and vertical movement of the style clip is controlled by the motor, which can move up and down automatically.
In this experiment, the fire risk was evaluated by simulating the effect of small flame caused by fault conditions.For other similar products in the market, it is necessary to start recording time with the left hand and pull the Bunsen lamp to the position where the sample is placed with the right hand at the beginning of the test. When the visual recording time is up, pull the Bunsen lamp back with the hand immediately.This instrument is designed to avoid uncoordinated misoperation by the user as much as possible. When the test starts, press "start" on the touch screen and the Bunsen lamp will automatically move right to the position of the sample. At the same time, the time relay will time, and the Bunsen lamp will automatically return to the starting position.
Product features
