Dew Point Sensor down to -70 °C Td (-94 °F Td)

Industrial drying applications, especially battery cell production, places stringent demands on dew point measurement. At low moisture levels, even small deviations can impact product quality, yield, and safety. Common processes such as opening doors or airlocks and load changes require stable signals. In this environment, a “frozen” or heavily averaged output during auto-calibration can create process blind spots. The TDS501 is designed to provide continuous dew point data down to -70 °C Td (-94 °F Td), enabling reliable process mapping 24/7 and supporting efficient dehumidification control. With a robust industrial design and straightforward integration with analogue and digital interfaces, the TDS501 helps reduce avoidable energy consumption and unplanned downtime.

• Fast response time and process reliability
• High repeatability and an accuracy of ±2 °C Td
• Pressure rating of up to 80 bar (1,160 psi)
• Responds immediately to dew point changes at all times
