1.Modular Design, Flexible Adaptation 

adopts advanced modular architecture, which mainly includes measurement module, wireless transmission module, power supply module and display control module. The modules are independent of each other and work together, so users can flexibly combine and configure them according to the actual application scenarios and needs. For example, in the monitoring of temperature, humidity, pressure and other environmental parameters, you can choose to match the corresponding high-precision measurement sensor module; if you need to transmit data over long distances, you can choose the LoRa wireless transmission module, which has a long transmission distance and strong signal stability; for occasions with high power supply requirements or the need for uninterrupted operation over a long period of time, the product can be equipped with a large-capacity Li-ion battery power supply module or an external stabilized power supply. This modularized design not only improves the product's performance, but also improves the product's performance. This modularized design not only improves the versatility and expandability of the products, but also facilitates the maintenance and upgrading in the later stage, which greatly reduces the user's cost and time cost. 

2. Low-power operation, long life 

In order to meet the continuous monitoring for a long time and use in the scenarios where the power supply can not be replaced frequently or the external power supply is inconvenient, the digital single meter has been optimized in the depth of the circuit design and chip selection to realize the low-power operation. Taking the built-in lithium battery power supply as an example, the average power consumption can be as low as a few milliwatts under the normal working mode. Combined with the highly efficient power management system, the power consumption can be intelligently adjusted according to the working state of the device, such as entering the low-power dormant mode in the interval of data collection, and waking up quickly when it needs to collect and transmit data, so as to ensure that battery life is prolonged to the maximum extent under the premise of not affecting the normal functioning of the device. The actual test, in the conventional industrial monitoring environment, the use of ordinary 19Ah lithium disposable battery power supply, can work continuously and stably for several years, greatly reducing the frequency of battery replacement, improve the stability and reliability of the equipment. 

3. Intelligent display and operation 

Clear and intuitive display: the digital single meter adopts a large LCD liquid crystal display, which can clearly present the measurement data, equipment status, transmission signal strength and other key information. The display has good readability, even in direct light or dim light environment, users can easily read the data. Meanwhile, through the simple and clear interface design, different types of data are distinguished by different colors or logos, such as normal measurement data is displayed in green, and abnormal data out of the preset range is alerted by flashing red, which is convenient for users to quickly identify and judge. 

Convenient operation experience: Equipped with humanized operation buttons, it can realize the parameter setting, function switching, data query and other operations of the device. Reasonable layout of the buttons and comfortable operation feel, even the first-time users can quickly get started. Some models also support the magnetic switch function, users only need to use the supporting magnetic tool near the device specific location, you can realize the device on or off, avoiding the frequent touch of the keys in complex environments may lead to misoperation, but also improve the device's waterproof, dustproof performance. In addition, for the digital display single meter with remote configuration function, users can adjust the parameters and set the alarm thresholds of the equipment remotely through the cell phone APP or computer software, without touching the equipment on site, which greatly improves the convenience and flexibility of the operation.
