The digital pressure gauge adopts LCD display technology, which will reduce the service life of the LCD screen in powerful use and may cause unclear data recognition of the digital pressure gauge. Therefore, the installation position of the digital pressure gauge is to avoid glare. If the digital pressure gauge or the consequences of safety accidents caused by strong light, the manufacturer of the digital pressure gauge will not be held responsible.

Digital pressure gauge
The liquid receiving part of the digital pressure gauge is made of stainless steel metal materials and ceramic sensors, which can directly measure weakly acidic and alkaline media. If measuring strongly acidic and alkaline media, more attention should be paid to the selection of digital pressure gauges. Do not mind using diaphragm digital pressure gauges.
The metal material and ceramic sensor of the stainless steel liquid receiving part of the digital pressure gauge can directly measure weakly alkaline media. If the selection of the strongly acidic media measured by the digital pressure gauge should pay more attention to the use of diaphragm type digital pressure gauges.
When using a digital pressure gauge at low temperatures (less than -30 ℃), it may cause malfunctions such as the digital pressure gauge not displaying. When using a digital pressure gauge at high temperatures above 85 ℃, a heat sink should be added, otherwise the measurement accuracy of the digital pressure gauge cannot be guaranteed, and there is a risk of lithium batteries exploding at high temperatures. During storage or transportation, attention should also be paid to the temperature of the digital pressure gauge.
Digital pressure gauges are used for low temperatures (less than 30 ℃), which can prevent faults from being displayed. If used under high temperature conditions exceeding 85 ℃, a heat sink should be added, otherwise the measurement accuracy of the digital pressure gauge cannot be guaranteed, and there is a risk of lithium battery explosion at high temperatures. During storage or transportation, attention should also be paid to the temperature of the digital pressure gauge.
