Overview of explosion-proof quartz clock:

The explosion-proof quartz clock is a fully quality and safe explosion-proof clock. The explosion-proof quartz clock is wall mounted and refined using advanced technology, with accurate and reliable travel time, beautiful appearance, and convenient use. It is an ideal timing tool. Suitable for places containing flammable and explosive gas mixtures, such as petroleum, chemical, oil depots, steel, coking, mining and other enterprises.

Usage of explosion-proof quartz clock:

1. Install the battery: Open the battery box and insert the battery according to the "+" and "-" pole markings indicated on the battery box. The second hand starts running, indicating that the explosion-proof clock is working properly.

2. Needle timing: Turn the needle wheel on the back of the movement to the standard time.

4、 Precautions for explosion-proof quartz clock:

1. The explosion-proof quartz clock is an intrinsically safe explosion-proof product, and any changes to the components in the circuit may affect the explosion-proof performance of the explosion-proof quartz clock. Therefore, users are required not to disassemble any electronic components inside the movement.

The power circuit of the explosion-proof clock is equipped with a safety protection device, and the replacement of the battery will not affect the explosion-proof performance of the explosion-proof quartz clock.
