Metric and Imperial Scale Gauges

-- Steady & Reliable Manufacturer --

Brief Description

We offer pressure gauges and thermometers calibrated with both Metric (bar, kPa, Celsius) and Imperial (psi, inHg, Fahrenheit) scales, catering to the diverse unit requirements of the global market and simplifying inventory management.

In-depth Overview

In international trade, fluid power systems often use metric units (e.g., bar or MPa), while North America primarily uses imperial units (psi). Our dual-scale or specialized single-unit gauges eliminate the need for field conversions, reducing the risk of reading errors and enhancing safety. Gauges can feature dual scales (e.g., psi on the outer ring, bar on the inner ring) or be manufactured solely in the required local unit. This customization is a key offering for distributors and OEMs operating in different regions worldwide.

Applications

Global OEM Manufacturing: Using the same physical gauge model but with different scale units for equipment destined for various global markets.
Maintenance and Repair: Simplifies replacement when service engineers may be trained on different unit systems.
Petrochemical Trading: Where process data may be tracked internationally using different units.
Calibration Labs: Using a dual-scale reference gauge to quickly check and verify instruments from any country.

Key Advantages

Minimizes Error: Direct reading in preferred units eliminates the risk of manual conversion mistakes.
Global Compliance: Ensures instruments comply with unit standards required by different national codes.
Inventory Efficiency: Dual-scale gauges can serve two markets with one stock keeping unit (SKU).
User Convenience: Allows technicians to work comfortably with their familiar unit of measure.

Payment and Shipping

We accept global payments via T/T and L/C. Standard dual-scale gauges are often available from stock, while single-unit custom scale printing has an MOQ and a 2−3 week lead time. We label and package units clearly according to their primary unit (PSI or BAR) to prevent warehouse picking errors before export.

Frequently Asked Questions

Q: Is a dual scale gauge less accurate than a single scale gauge?
A: No. The accuracy is determined by the internal Bourdon tube or sensing element. The dual scale simply includes a calculated conversion on the dial face; the underlying precision remains the same.

Q: What are the two main thread standards for pressure gauges?
A: The two main standards are NPT (National Pipe Thread), a tapered thread common in North America, and BSPP (British Standard Pipe Parallel) or BSPT (Tapered), common in Europe and Asia. We manufacture gauges with both to ensure perfect fitment.

Q: Can I order a gauge with a custom unit, like kg/cm2?
A: Yes. We frequently produce gauges with custom units of measure, including kg/cm2 (kilograms per square centimeter) and mmHg (millimeters of mercury), upon request, subject to MOQ requirements.
