| Detonator Circuit Tester | ||
| 1. ‘NMC’ intrinsically safe Continuity Circuit Tester primarily determines the continuity of blasting circuit. Metalliferous & Coal Mines Regulation 169 (5) States, “When More than one shot are to be fired at the same time; the circuit shall be tested, either for electrical resistance or for continuity, before connecting it to the firing apparatus. Such a test shall be made with an apparatus specifically designed for the purpose.” |

| Pitot Tube | ||
| Pitot Tube is standard air velocity meter. It consists of two concentric tubes. Inner one measures total pressure existing in the fluid stream, the outer measures static pressure only.
When these tubes are connected to Manometers only the velocity pressure is registered. This pressure is a measure of linear velocity of gases. |

| Portable Inclined Manometer | ||
| Pitot readings are very small for the common range of air velocities. Ordinary U-tube manometers are not useful for measurement of gas velocities below 12 rn/s. For this,use of inclined tube manometer is suggested. These manometers are well-type with single limb indication. “NMC” Inclined Manometer can be swivelled in 4 positions- 1 in 20, 1 in 10, 1 in 5 & vertical (Approx) Maximum limit of pressure measurement is 250 mm wg. |
