Zedeyes 160 mm High-Precision Master  Gauge

The Zedeyes 160 mm High Precision Master Gauge is a reference-grade industrial pressure instrument designed for metrology laboratories, calibration facilities, and high-precision field testing. Engineered with an exceptional Class 0.25 accuracy rating ($\pm0.25\%$ of full scale), this master gauge provides the reliable measurement performance required to calibrate secondary pressure instruments, test benches, and critical process systems.

Enclosed in a matte stainless steel housing with high-grade SS316 wetted parts, it combines corrosion resistance, anti-glare readability, and long-term calibration stability across demanding test environments.

Key Features & Benefits

• Class 0.25 Master Calibration Grade: Engineered to strict reference accuracy standards, making it the ideal master standard for testing, certifying, and calibrating industrial pressure transmitters, switches, and working gauges.

• Large 160 mm High-Resolution Dial: The expanded dial diameter paired with fine scale graduations minimizes parallax error and enables precise scale interpolation.

• Corrosion-Resistant SS316 Wetted Parts: Stainless steel 316 process connection and measuring element ensure compatibility with aggressive liquid and gaseous media.

• Anti-Glare Matte Stainless Steel Case: Heavy-duty matte housing prevents surface reflections and glare under bright laboratory lighting or direct outdoor sunlight.

• High Measurement Repeatability: Built for minimal hysteresis and low thermal drift to maintain precision across long testing cycles and calibration intervals.

Primary Applications

• Metrology & Calibration Laboratories: Primary or secondary reference standard for pressure gauge calibration skids and verification rigs.

• Quality Control & Laboratory Testing: Precision pressure verification during factory acceptance testing (FAT), valve leakage testing, and hydrostatic line testing.

• Critical Industrial Automation: High-accuracy pressure loops in chemical processing, aerospace test facilities, and pharmaceutical utilities.

• Mobile Field Calibration Units: Portable, rugged reference standard for field service technicians performing on-site calibration.
