1ã€Material--select high-quality stainless steel Stainless steel with low nickel content can ensure rust prevention, and it is not easy to cause allergies. It is an important factor to ensure the appearance of the watch. The most commonly used is 316L high quality stainless steel.
TIPS: How to determine whether the stainless steel back cover is marked with English: StainlessSteel, which means that the watch is made of stainless steel; if the mark is: StainlessSteelCase, it indicates that the case of the watch is stainless steel, the watchband is not.
2, waterproof - at least waterproof 30 meters waterproof 30 meters refers to the watch in a laboratory environment, able to withstand the pressure of 3 atmospheres. In the actual life of a near-electricity alarm, a waterproof watch with a height of 30 meters cannot ensure that water does not enter the water at a depth of 30 meters. Therefore, waterproof watches with a length of 30 meters are generally not recommended for swimming or bathing. However, a waterproof watch with a length of 30 meters can ensure daily waterproofing of the watch, such as: water droplets floating in rainy days; water drops splashed by hands; sweat oozing from the skin surface. Water vapor will solidify after entering most of the high-grade watch body. It needs to be opened and repaired in time, otherwise moisture will corrode the movement components.
TIPS: How to determine whether the 30m water meter cover is marked in English: waterresistance30m (or 3atm), which means that the watch waterproof to 30 meters or 3 atmospheres.
3, movement - high-quality movement is like the heart of the human body, or like the car's engine, is the most important part of the senior watch. A high-quality movement is crucial to ensure that the watch is working long hours. The reliability of the movement is generally judged by origin or brand.
TIPS: How to determine the origin of the movement In general, at the 6 o'clock position on the dial, there is a watch “SwissMade†made in Switzerland, including the movement. But do not rule out the use of this "SwissMade" logo, suggest that before buying, the brand you plan to buy online inquiries to determine whether it is genuine Swiss manufacturing.
Near power alarm function:
Proximity alarm high voltage has anti-electric shock pre-alarm function: when you wear a near-electricity alarm and mistakenly enter the charged area (or will be mistaken into the live body, with a live pole) to a certain distance, the near-electricity alarm can issue a continuous alarm The sound reminds you of the danger of being charged. When you hear the alarm sound, you should quickly move away from the high-voltage live zone until the power-on alarm stops the alarm sound. This anti-electrical pre-alarm function of the near-electricity alarm (also known as the near-electricity alarm function) can prevent accidents caused by electric shock due to illusions and mistakes.
The near-electricity alarm low-voltage has the function of inspecting electricity: it can be used in the absence of contact with the wire, and the near-electricity alarm device is used to detect whether the live wire above AC 110V has electricity. Or for the detection of cable and low voltage wire breaks. Or used to check the direction of the wire that steals the wall of an electric user.
Near-electricity alarms are ideal warning-type auxiliary safety devices for high-voltage power operators.
Near electric alarm product features:
1, a wide range of applicable voltage.
2, the alarm is accurate and reliable.
3, small size, easy to wear.
4. It is a dual purpose watch with close alarm and accurate timing.
5, beautiful appearance.
Precautions:
1, before wearing a watch type electric alarm device must be on the 220V AC before the use of the test (confirm that the alarm is in normal working condition).
2. It is forbidden to use the alarm for a voltage alarm at a lower voltage level to prevent the actual alarm distance from being less than the safety distance.
3, operating personnel should strictly abide by the "electricity safety work regulations" in the relevant provisions.
Near power alarm warranty and repair:
The warranty period of this product is one year. From the date of user's purchase, during the warranty period, if the fault occurred due to non-user error, the user will repair it for free with the warranty card. For products that have passed the warranty period, only the material and postage required for maintenance will be charged.
