The SUTO S211 compact dew point meter is an economical and reliable dew point monitoring solution for industrial applications that comply with ISO 8573-1. Compact and powerful, it is the perfect choice for measuring the dew point of adsorption dryers.
The SUTO S215 dew point meter provides reliable dew point monitoring in industrial applications. The +50 °C Td offers long-term stability and high accuracy over the entire range. In addition, its compact design makes it an ideal solution for measuring the dew point of compressed air in freeze-type dryers.
The SUTO S220 dew point meter provides reliable and long-term stable dew point monitoring for compressed air and gases in industrial applications. The dew point meter has a measuring range of -100... The +20 °C Td is ideal for measuring dew points in high-tech industries and under special conditions that require compliance with ISO 8573-1 for compressed air quality.
Unique triple sensor
SUTO's QCM sensor is the result of years of high-tech research and development. The sensor is designed for low dew points that cannot be measured by other sensors. The S220 combines QCM with a well-known polymer sensor that automatically switches between the two sensor elements as needed, making it the first dew point meter in the world to achieve accurate measurement over the entire range -100 °C Td to +20 °C Td.
By installing an optional pressure sensor in the dew point meter, SUTO integrates four sensor elements, polymer, QCM, Pt100, and pressure sensors, into one instrument.
Various output connections
The S220 dew point meter supports 2-wire or 3-wire analog 4... 20 mA output signal, also provides Modbus/RTU digital interface.
These different signal outputs allow the S220 to be seamlessly integrated into the user's production process, benefiting from great flexibility. The S220 can be easily connected to SUTO's display and data loggers S330/331 and S551 for optimal fixed or portable data recording, and can also be connected to third-party devices.
An optional display displays the measured values
An optional OLED display mounted directly on the dew point meter is used to read measurements in real time in the field. The display can be easily rotated 340°, suitable for various occasions. The display cover is made of strong polycarbonate and ABS reinforced to work in harsh environments.
The strong material guarantees long-term stable measurement
The body of the S220 is made of high-grade aluminum alloy with a soft finish. The process connection material is 1.4301 (SUS 304) stainless steel for durability. The top cover is made of aluminum of the same quality as the main body.
