KELLER Pressure will exhibit at the Sewer Exhibition '26 in Tokyo! From August 4 to August 7, 2026, at Tokyo Big Sight, West Hall 1, Booth 1-702.

KELLER Pressure Japan 日本支社

KELLER Pressure offers immersion-type high-precision level gauges suitable for a wide range of applications. Optimized housing and cable designs tailored to specific applications and environments ensure reliable measurements even under harsh conditions. All piezoresistive level gauges are developed, manufactured, and calibrated at the headquarters in Winterthur, Switzerland, boasting Swiss quality and high precision that have been proven over many years. They not only achieve stable performance with no maintenance required for long periods but also support various commonly used interfaces, enabling optimal integration and communication with systems. In particular, products compatible with RS485 are ideal for battery-operated and remote control systems in environmental measurement and water-related fields.
