"Non-burning, nicotine for users, low tar content. As the heating temperature (below 500℃) is lower than the combustion temperature of traditional cigarettes (600-900℃), the harmful components produced by tobacco high-temperature combustion pyrolysis and thermal synthesis are reduced, and the release amount of side-flow smoke and environmental smoke (second-hand smoke) is also greatly reduced."
Heating non - combustion products are electronic devices containing tobacco. When you heat them, they produce a nicotine-containing vapor that you can inhale. Hnb Device Oem,Hnb Device Patent,Hnb Device,Hnb Device For Sale Shenzhen MASON VAP Technology Co., Ltd. , https://www.cbdvapefactory.com
The transformer core grounding current tester host adopts high-speed microprocessor, which can display the magnitude and waveform of the measured current in real time. The FFT transform and digital filtering technology are used to make the test data more accurate. It has alarm threshold setting and alarm indication function. With date and time setting function; with automatic shutdown or no automatic shutdown setting function; with the function of setting the tested point number; can store 100 sets of data and waveform.
2. Adopting the latest magnetic shielding technology, the external magnetic field has little influence and strong anti-interference ability, ensuring high precision, high stability and high reliability of uninterrupted measurement throughout the year. 3, the inner diameter of the jaw is 80mm × 80mm, can clamp the cable or ground wire below φ80mm, or clamp 96mm × 4mm flat steel ground wire, portable clamp design, do not need to disconnect the line under test, non-contact measurement, safe and fast.
They are different from traditional cigarettes and work by heating tobacco to a very low temperature. Tobacco is heated to 350 ° C in a heat-incombustible device, while traditional cigarettes burn at up to 900 ° C.
Still, the temperature at which non-combustion products are heated is high enough to vaporize and inhale harmful chemicals.
Although both are electronic devices, heated non-combustible products are also different from e-cigarettes or steam devices. These usually use chemical liquids and do not necessarily contain nicotine. E-cigarettes tend to heat liquids to around 250 degrees Celsius to produce vapor.
Transformer core grounding current tester function use
Product introduction:
The normal operation of the transformer core is grounded at a single point. If there are two or more points at the same time, the current loop will be formed between the core and the earth. The maximum current can reach several tens of amperes, which will cause the core to overheat. Even burned. The transformer core grounding current tester can quickly find the fault of the transformer's latent fault, which is the main tool to ensure the safe operation and normal maintenance of the transformer. It is mainly used for leakage current testing of iron cores and clamps of electrical equipment such as transformers and reactors in substations and power plants. It can also be used for current and leakage current testing of lines or equipment in electric power, communication, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises.
