Key Features

• NIST TRACEABLE CERTIFICATE: Each gauge is individually calibrated and includes a serialized NIST Traceable Certificate of Calibration, supporting safety audits, lab requirements, and quality control compliance.
• ASME B40.1 GRADE A ACCURACY: Professionally manufactured to meet strict Grade A standards (+/-2-1-2% of span); features high-contrast markings on a 2-1/2" (63mm) dial for repeated high-precision measurement.
• STABLE VIBRATION DAMPENING: Glycerin-filled case stabilizes the pointer against vibration and pulsation; prevents needle flutter to maintain the reading accuracy required for certified testing and inspections.
• HEAVY-DUTY CERTIFIED BUILD: Rust-resistant 304 stainless steel case with durable brass wetted parts and polycarbonate lens, built to maintain calibration integrity in harsh industrial or commercial environments.
• STANDARD 1/4" NPT CONNECTION: Universal lower mount fitment for easy installation into regulators and manifolds. Please verify connection size before ordering. (Note: Not for oxygen service).
