Manufacturer: Wenchi Electric Ignition Instruments Co., Ltd. Summary: This kind of electric igniter is the most popular and generally consumed product both at home and abroad, its fixed insulation sheet adopts the two-sided tinned copperplate. In order to improve the ignition sensitivity, you can make a change to the bridge wire of igniter: A random igniter powder agent can be used with one of any bridge wires of igniters. The powder heads adopt single-layer ignition powder with the powder heads kept at the same size, which can make the performance same. This type of igniter has the top-ranking qualification in the world. All parameters are in the permitted range of related criterion and we absolutely guarantee the ignition of connection in series to be perfectly normal, no phenomenon of failed ignition. Every batch of igniters quality is stable and we ensure all igniters can be fired in milliseconds. View the drawing two.
