Explosive & Combustible

The digital electric detonator (EDD) is a high-ranking intelligent product . Comparing with the common delay detonator, the EDD has three advantages: 1. High accuracy: Mean variation and it’s less than 0.2% in comparison with that 10% of the common delay detonator. 2. High reliability: The EDD performance doesn’t change under 70m water for 72hrs. The EDD misfire ratio is one millionth comparing with that of common detonator between one ten thousandth and one hundreds of thousandth. 3. High safety: Anti-static and anti-radio frequency.

1. Digital Electronic Detonator Initiation system
Digital electronic detonator(EDD) consists of special logger, blasting machine and digital electronic detonator(EDD), which can meet all kinds of complex blasting designs.
Logger is mainly used for the set and modification of EDD delay time, which can record 1600pcs EDD and test each branch.
Blasting machine is mainly used for the ignition of EDD with igniting power of 1600pcs EDD, which can verify the network ensuing the reliable blasting.
2. Three advantages of Digital Electronic Detonator:
(1). High accuracy: Mean variation and it’s less than 0.2% in comparison with that 10% of the common delay detonator.
(2). High reliability: The EDD performance doesn’t change under 70m water for 72hrs in comparison with that of common shock tube detonator 1m for 24hrs. The EDD misfire ratio is one millionth comparing with that of common detonator between one ten thousandth and one hundreds of thousandth.
(3). High safety: Anti-static and anti-ratio frequency.
