The TS-500L and TS-1000L detonator checkers are intended for use as intermediate detonators for initiating borehole and other charges of low-sensitivity industrial explosives, including water-containing explosives, with a temperature when charging wells of no more than 85 ° C, during blasting operations on the Earth's surface and in the faces of underground workings of mines and mines, not exceeding hazardous by gas or dust, in all climatic regions of the CIS countries at ambient temperatures from -50 to +50 ° C.

Checkers detonators TS-500L and TS-1000L can be used for conducting blasting operations when initiated from non-electric initiation systems of the type "SYNV" or "Edilin", or from the detonating cord ДШЭ-12, ДШЭ-6 or other detonating cords with a core mass of at least 6 g/ m for blasting in dry and watered wells, including those with running water with a pH of 3-7 with a charge retention period of up to 7 days in water at a hydrostatic pressure of up to 0.2 MPa (2 kg/cm2).
