In industrial settings, whether for routine instrument verification, equipment commissioning, or fault troubleshooting, pressure calibration is a critical and frequent task. Traditional large benchtop calibration devices are cumbersome to carry and often struggle to cope with complex field environments. Xi'an Xinyi Instrument Technology Co., Ltd., deeply understanding the needs of field engineers, proudly introduces the YHP-70 Portable Pressure Calibration Pump. This product integrates high-precision control, wide range coverage, and rugged portability into a single unit. Featuring a lightweight yet durable aluminum alloy body, it can easily generate stable pressure from negative pressure (vacuum) up to 60 MPa. With excellent control precision of ±0.05% FS, it becomes the ideal tool for on-site calibration of pressure gauges, pressure transmitters, pressure switches, and other instruments in industries such as petrochemicals, power generation, metallurgy, HVAC, and metrology.
1. Full Range Coverage, One Pump for Multiple Uses
The YHP-70 boasts powerful pressure generation capability, with an adjustment range covering -0.1 to 60 MPa. This means it can generate negative pressure for calibrating vacuum gauges and easily output high pressure up to 600 bar, meeting the vast majority of on-site calibration needs, from low-pressure pneumatic systems to ultra-high-pressure hydraulic systems. Truly "one pump for all ranges."
2. Precision Fine-Tuning, Accurate Pressure Control
The essence of calibration lies in "precision." The YHP-70 features a meticulously designed volume adjuster paired with a sensitive fine adjustment valve, allowing operators to finely and smoothly regulate the output pressure, easily locking onto any set point. Its control finesse is sufficient to work with master gauges of ±0.05% FS accuracy to complete highly credible verification of various industrial instruments.
3. Rugged and Portable, Adaptable to Harsh Sites
Constructed from high-strength aluminum alloy, the entire unit weighs only 3.5 kg and has a compact size (300*200*150 mm). Equipped with a comfortable carrying handle, it is easily transported to any calibration location, such as pipe trenches, elevated platforms, or remote well sites. Its sealing system ensures long-term pressure stability after generation without leakage. Furthermore, the pump body is compatible with air or clean water as the working medium, offering flexibility in use.
