Product Description
The YK120B digital pressure gauge is a high-precision, battery-powered or externally powered instrument designed for reliable pressure measurement in both laboratory and industrial environments. Featuring a large 5-digit LCD display with backlight, the YK120B provides clear readings even in low-light conditions. Its stainless steel housing (304 or 316) ensures excellent durability and protection against harsh environments, with an IP65 minimum ingress protection rating.
The gauge delivers outstanding accuracy of ±0.05% FS (optional ±0.02% FS) and supports multiple switchable pressure units, including kPa, Bar, psi, MPa, kgf/cm², and mmHg. For system integration, optional outputs such as 4–20 mA analog, RS485 Modbus RTU, and data logging are available.
The YK120B is simple to operate, offers long-term stability, and requires minimal maintenance. Its zero-point calibration function allows users to easily adjust the gauge on site, ensuring consistent performance over time.





Application Range
The YK120B digital pressure gauge is widely used in:
Hydraulic & pneumatic systems – monitoring pump output, filter differential pressure, and cylinder pressure
Water treatment & plumbing – measuring line pressure in water supply, booster stations, and irrigation systems
Oil & gas industry – compatible with non-corrosive and mildly corrosive media such as gas, air, and hydraulic oil
Laboratory & calibration – ideal for precision testing, pressure calibration, and research experiments
HVAC & refrigeration – checking refrigerant pressure and system performance
Industrial machinery – pressure monitoring on compressors, presses, and process equipment
With its combination of accuracy, durability, and flexible output options, the YK120B is a versatile solution for most pressure measurement needs.
