Dew Point Meter & Sampling Unit (SM Series)

Summits SM Series Dew Point Meters are precision moisture monitoring instruments engineered to measure pressure dew point levels in compressed air and gas systems. Designed as portable or panel-mounted sampling units, these systems provide accurate real-time moisture analysis essential for validating dryer performance and ensuring process air quality compliance.

The sampling unit incorporates a complete measurement assembly including ball valve isolation, pressure regulator, measuring chamber, flow control meter, dew point transmitter, and non-return valve protection. This configuration ensures stable sample conditioning before moisture analysis.

The dew point transmitter measures moisture levels across a wide range from –80°C to +20°C dew point with high repeatability. Electrical signals proportional to moisture concentration are transmitted to a process indicator for display and monitoring.

The process indicator features multi-resolution LED display with retransmission outputs including 4–20 mA, 0–10V, and RS485 Modbus RTU communication for BMS / SCADA integration.

Sensor assemblies are protected using sintered stainless steel filters preventing contamination ingress. Lightweight aluminium modular enclosures enable portability and field deployment for compressed air audits and dryer validation testing.

These instruments are widely used in pharmaceuticals, instrumentation air, food processing, PET blowing, electronics manufacturing, and critical compressed air quality monitoring applications.
