In 1997, Vaisala launched a new type of dew point sensor called DRYCAP, based on polymer thin film technology. Since then, the applications of the DRYCAP series have expanded to a very wide range, including drying processes, compressed air, and dry chambers. DRYCAP sensors are particularly valued for their reliable performance in high-temperature and very dry environments.

The Vaisala BAROCAP, released in 1985, is a silicon-based micromechanical pressure sensor that provides reliable performance for a wide range of applications, from weather observation to industrial measurement. The BAROCAP sensor combines two effective technologies: single-crystal silicon material and capacitive measurement, featuring high accuracy and long-term stability, along with low hysteresis.

The "DMP7" is a dew point probe designed for measurements in low dew point environments. Its short design makes it suitable for installation in space-constrained areas such as semiconductor manufacturing equipment. Additionally, it can be used in various applications including industrial drying processes, compressed air systems, dry rooms, and blanket gases in metal heat treatment. 【Features】 ■ Dew point measurement range: -70 to +80°C Td/f ■ Accuracy of dew point measurement: up to ±2°C Td/f ■ Chemical resistance through chemical purging ■ Resistant to condensation, oil, dust, and most chemicals ■ Output signal: Modbus RTU (RS-485) *For more details, please refer to the PDF document or feel free to contact us.

The "DMP8" is a dew point probe designed for measurement in industrial low dew point environments such as industrial drying processes, compressed air systems, and the semiconductor industry. It can be mounted on a 1/2" NPT or 1/2" ISO PT thread, and the insertion length is adjustable. In environments with high concentrations of chemicals and cleaning agents, it activates chemical purging to maintain measurement accuracy until the next calibration. 【Features】 ■ Dew point measurement range: -70 to +80°C Td/f ■ Dew point measurement accuracy: up to ±2°C Td/f ■ Operating pressure range: 0 to 4 MPa ■ Adjustable insertion length of the probe ■ Resistant to condensation, oil, dust, and chemicals

The Vaisala DRYCAP(R) DMT345/DMT346 dew point transmitter is an ideal measurement device for industrial drying equipment that performs direct dew point measurements in high-temperature environments, such as cooking ovens and high-temperature dryers, without using a sampling system. The Vaisala DRYCAP(R) sensor provides accurate and reliable measurements with excellent long-term stability and fast response.

The DMT152, designed for low dew point measurement capable of measuring down to -80°C, is ideal for industrial applications such as the semiconductor industry, pure gases, dryers, glove boxes, drying chambers, and additive manufacturing, as well as for applications requiring trace moisture management.

The DMT143 and DMT143L dew point converters provide accurate dew point measurements and are suitable for small compressed air dryers, plastic dryers, additive manufacturing, and other OEM applications. Both models can be easily connected and used with the Vaisala DM70 handheld dew point meter. The long probe type DMT143L is the successor to the Vaisala DRYCAP® DMT242 dew point converter. 【Features】 ■ Automatic correction function with Vaisala DRYCAP® technology ■ Rapid response ■ Dew point measurement range: -70 to +60°C ■ Accuracy: ±2ºC ■ Resistance to condensation ■ Compatible with Vaisala DRYCAP® DM70 handheld dew point meter ■ Traceable calibration (includes English calibration certificate) ■ LED alarm indicating excessive dew point levels *For more details, please contact us or view the PDF data available for download.

The DM70 handheld dew point meter for spot checks enables accurate and rapid dew point measurement in industrial fields such as compressed air, metal processing, additive manufacturing, and food and plastic drying processes. By combining the optional MI70 Link Windows® software with a USB connection cable, it is possible to transfer recorded data and real-time measurement data from the DM70 to a PC.

The Vaisala DPT145 multi-parameter transmitter for SF6 gas is an innovative, uniquely developed product that enables online measurement of dew point, pressure, and temperature. Additionally, it calculates values for four parameters, including SF6 concentration. The DPT145 is particularly well-suited for integration into OEM systems.

The DPT146 dew point pressure transmitter allows for easy monitoring of compressed air. The DPT146 is ideal for the use and monitoring of compressed air as it simultaneously measures both dew point and process pressure.
