FAQ
What is digital pressure gauge?
Digital pressure gauge combines the microprocessor technology and advanced AD conversion algorithm. Every gauge has a Large-screen LCD, and unique background light make the data clear and easy to read at night. It adopt advanced chip, realize peak value holding, data memory and measurement, it also provide clear zero function. The shell is fully sealed with stainless steel, which is resistant to corrosion and vibration, and can be used in a variety of complex environments.
What are the differences between analog and digital?
Digital pressure gauge reads the pressure value directly on the display, but analog pressure gauges require the operator to read the value from the needle position on the pressure gauge. Therefore, the pressure value displayed by the digital pressure gauge is more intuitive and the reading is more convenient.
Which is better analog VS digital pressure gauge?
Although the digital pressure gauge has high precision, easy to read and good stability, But because analog pressure gauges are cheap and easy to set up, so it replaces the analog pressure gauge in partial scenes. All analog pressure need is a pressure source and a process of conversion, no need power. So, there is no way to say which is better, and the one that fits the your requirement is the best.
