Welcome to Zhengzhou Zhishichangyun Technology Co. Ltd. – your trusted manufacturer of high-quality industrial instrumentation. Since 2014, we have specialized in producing durable, precision measurement solutions for global markets. Our Industrial Shockproof High-Precision Pressure Gauge for Gas Pipeline is engineered to deliver reliable performance under harsh conditions, ensuring accurate pressure monitoring in critical gas transmission systems. With a 5,000-10,000 sqm factory and ISO9001/ISO14000 certified processes, we bring you a gauge that combines robustness with customizability, backed by annual exports of US$1.5-2.5 million to over 15 countries.
Key Features & Technical Specifications
Shockproof Design: Built-in glycerin filling dampens vibration and pulsation, extending gauge life in gas pipeline environments where pressure spikes are common.
High Precision: Standard accuracy of ±1.0% FS, with optional ±0.5% FS for critical applications. Laser-calibrated movement ensures repeatable readings.
Durable Construction: Stainless steel case and brass/316L wetted parts resist corrosion from natural gas, methane, and other industrial gases. The IP65 protection rating guards against dust and water ingress.
Customizable Options: Choose from multiple pressure ranges (0-5000 psi), dial sizes (2.5 to 6 inches), and connection threads (NPT, BSP, metric). Custom scale markings and logo printing are available upon request.
Wide Application: Ideal for gas pipelines, compressor stations, pressure regulators, and industrial boilers. Suitable for both gaseous and liquid media, with optional oxygen-cleaning for special applications.
User-Friendly Design: Large, clear dial with white background and black graduations for easy reading. The blow-out back provides additional safety in case of overpressure.

Why Choose Our Pressure Gauge?
The core advantage of this gauge lies in its shockproof mechanism: the glycerin-filled case absorbs mechanical shocks and pulsations, reducing pointer fluctuation and preventing premature wear. This is especially critical in gas pipeline applications where compressors, valves, and flow variations create constant vibration. The result is a longer service life and fewer false readings, saving you maintenance costs and downtime.
Furthermore, our high-precision movement uses a brass alloy that resists fatigue and corrosion. Each gauge is individually calibrated in our temperature-controlled lab, ensuring traceable accuracy. The customizable options allow you to tailor the gauge to your exact system requirements – from thread type to range to dial markings – making it a versatile solution for OEMs, distributors, and engineering firms.
As a manufacturer with ISO9001 and ISO14000 certifications, we follow strict quality control procedures.

Frequently Asked Questions
Q: What is the minimum order quantity (MOQ) for this pressure gauge?
A: For standard models, the MOQ is 50 pieces. For customized versions (with specific range, thread, or logo), the MOQ is 100 pieces. We can discuss smaller trial orders for new clients.Q: Can the gauge be used for oxygen or other reactive gases?
A: Yes, but for oxygen service we recommend our oxygen-cleaned version with Halocarbon fill fluid and special cleaning to remove hydrocarbons. Please specify this requirement when ordering.Q: How long does it take to deliver a customized gauge?
A: Typical lead time for custom orders is 15-25 working days, depending on quantity and complexity. Standard models can ship within 7-10 working days from our warehouse.Q: What is the IP rating, and can it be used outdoors?
A: The standard gauge is IP65, meaning it is dust-tight and protected against water jets. It is suitable for outdoor use as long as the case is not submerged. For higher protection, we offer an IP67 option.Q: Do you provide calibration certificates?
A: Yes, we provide a traceable calibration certificate for each gauge. ISO 17025 accredited certificates are available at an additional cost.Q: Can I get a sample before placing a bulk order?
A: Absolutely. We offer sample orders with a nominal fee, which is refundable when you place a bulk order. Samples are typically shipped within 5 working days.Q: What warranty do you offer?
A: We offer a 12-month warranty from the date of shipment against manufacturing defects. The warranty covers repair or replacement of the gauge, excluding damage from misuse or improper installation.Q: How do I choose the correct pressure range?
A: We recommend selecting a range where the normal operating pressure is between 50% and 75% of the full scale. For example, if your line pressure is 500 psi, choose a 0-1000 psi gauge. Our technical team can assist you with selection.
