1. Excellent anti-interference ability, stable measurement results 

• Electromagnetic shielding design: in order to cope with the complex electromagnetic environment, the digital vacuum gauge adopts multiple layers of high-precision electromagnetic shielding materials inside the casing. These shielding layers can effectively block the intrusion of external electromagnetic interference signals to ensure that the internal measurement circuit and sensor work stably. In industrial production workshops, there are often a large number of running motors, frequency converters and other sources of strong electromagnetic interference around, ordinary vacuum gauge in this environment, the measurement data may fluctuate dramatically or even error, but this product, with its excellent electromagnetic shielding design, can resist these interferences, stable output of accurate vacuum degree measurement value.

• Optimized Filtering Algorithm: The built-in advanced digital signal processing chip runs a deeply optimized filtering algorithm. The algorithm can process the signals collected by the sensor in real time, effectively filtering out all kinds of noise interference, including high-frequency noise, low-frequency drift and periodic interference. Even in the case of disturbances such as voltage and current fluctuations caused by the start and stop of vacuum equipment, the filtering algorithm ensures that the final vacuum data displayed is true and reliable, reduces measurement errors, and provides users with stable and accurate measurement results.

2. Convenient portable design 

• Lightweight body: the overall use of compact, lightweight design concept, the body is small and delicate, light weight. The size of the product has been carefully designed to facilitate one-handed operation, whether it is moving between different experimental benches in the laboratory, or in the process of equipment inspection in the industrial site, it can be easily carried into the pocket of the work clothes or toolkit, and vacuum measurements anytime, anywhere, which greatly improves the work efficiency, and gets rid of the constraints of the traditional large-scale vacuum measurement equipment which has a huge volume and is inconvenient to move.

• Humanized operation interface: Equipped with simple and intuitive operation interface, the large LCD screen clearly presents key information such as measurement data, unit, range and equipment status. The display has a good viewing angle and high contrast, even in direct light or dim light environment, users can still read the data clearly. The operating buttons are well laid out with clear functions. With simple button operation, users can easily realize range switching, unit conversion, data zeroing, peak hold and other commonly used functions. For example, when you need to quickly check the highest vacuum level in a period of time, you only need to press the peak hold button, and the display will lock and show the maximum measurement value in that period of time, which is convenient and quick.

• Long Battery Life: To meet the needs of users who use the gauge for long periods of time outdoors or in environments without power outlets, the gauge has a built-in high-performance rechargeable lithium battery. The battery has excellent endurance, a full charge, under normal use frequency, can work continuously for several hours. At the same time, the product also supports the function of charging and using at the same time, when the battery power is insufficient, the user can connect the mobile power supply or power adapter to charge through the USB interface, without affecting the normal measurement work. In addition, the device is also equipped with a power display function, real-time reminder of the remaining battery power, so as to prepare for charging in advance.
