This includes range adjustments, material selection, and the addition of special features.

The delivery time for customized products depends on the specific customization content and production schedule. Generally, after receiving the customization request, we will assess it as soon as possible and provide an estimated delivery time.

We offer comprehensive technical support, including product selection consultation, installation guidance, troubleshooting, and resolution. Customers can contact us via phone, email, or online chat tools to obtain timely technical support.

Mining pressure gauges must comply with mining safety regulations and relevant industry standards, such as explosion-proof, dust-proof, and shock-resistant requirements, to ensure safe use in high-risk environments like mines.

Mining pressure gauges undergo strict quality control and regular calibration to ensure accurate readings. Additionally, choosing brands with explosion-proof certification and a good reputation is crucial for safeguarding safety.

Using special materials and sealing designs, such as stainless steel casings and high/low temperature-resistant seals, can effectively improve the durability and performance stability of mining pressure gauges in extreme temperature, humidity, dust, and other environments.

Once a mining pressure gauge is found to be malfunctioning or displaying abnormal readings, it should be immediately stopped from use and a professional maintenance technician should be contacted for inspection and repair. Do not attempt to dismantle or repair it yourself to avoid causing a safety accident.
