Product Introduction

The YS-039 is a high-performance, portable pressure calibrator and hand pump designed for on-site and laboratory pressure calibration. It combines a precision pressure pump with fine adjustment capability, supporting both pneumatic (up to 2 MPa / 300 psi) and hydraulic (up to 100 MPa / 15000 psi) operation. Built with corrosion-resistant aluminum alloy and high-grade seals, the YS-039 ensures leak-proof performance and long service life. The standard 1/4" NPT connection allows easy attachment to pressure gauges, transmitters, switches, and sensors. Its lightweight, handheld design (approx. 1.4 kg) makes it ideal for field technicians who need accurate, reliable pressure generation without bulky equipment. Optional digital pressure display and factory calibration certificate are available.

Application Scope

The YS-039 is widely used in industries requiring routine pressure instrument verification and maintenance, including:

• Industrial manufacturing – Calibration of pressure gauges, transmitters, and switches on production lines

• Oil & gas and petrochemical – Field verification of pressure instruments on pipelines and storage tanks

• Power generation – Maintenance of pressure switches and sensors in thermal, nuclear, and hydro power plants

• HVAC and refrigeration – Checking pressure controls and sensors in heating, ventilation, and air conditioning systems

• Water treatment and pump stations – Calibration of pressure transmitters and flow-related instruments

• Laboratory and R&D – Accurate pressure source for testing and instrument validation

• Pharmaceutical and food processing – Sanitary pressure device calibration where clean, non-contaminating media are required (hydraulic version with distilled water)

• Marine and offshore – On-site calibration of pneumatic and hydraulic control systems

The YS-039 is suitable for any application where portable, stable, and precise pressure generation is needed.

5 Key Selling Points (Bullet Points)

1. High Accuracy & Fine Adjustment – Achieve stable pressure output with ±0.05% FS accuracy and a built-in fine adjustment valve for precise calibration of gauges, transmitters, and switches.

2. Dual-Function Portability – Lightweight, hand-held design combines a pressure pump and calibrator in one unit, ideal for field service, lab, and industrial maintenance.

3. Wide Pressure Range & Media Compatibility – Supports pneumatic (air) up to 2 MPa (300 psi) or hydraulic (oil/water) up to 100 MPa (15000 psi) based on model variant; works with most gauge types.

4. Durable & Leak-Proof Construction – Made with corrosion-resistant aluminum alloy and high-grade seals, tested for zero leakage under rated pressure for long-term reliability.

5. User-Friendly Interface – Simple one-handed operation, standard 1/4" NPT or BSP quick connectors, and optional digital pressure display for easy reading.
