The AELAB DP29 Chilled Mirror Dew Point Instrument is a multifunctional portable dew point humidity meter specifically designed for accurate field dew point measurement and laboratory reference applications. The DP29 series applies the chilled mirror measurement principle to quantify dew point temperature with high stability, enabling consistent chilled mirror dew point analysis without the need to repeatedly calibrate.
The AELAB DP29 Chilled Mirror Dew Point Instrument is typically used for dew point measurement of SF6 gas and for controlled moisture management processes. Integrated electronic sample gas flow monitoring and RS-232 data output support reliable chilled mirror dew point measurement workflows and PC-based data management in industrial quality control, environmental testing, and diagnostic laboratory analysis.
The AELAB DP29 Chilled Mirror Dew Point Instrument integrates semiconductor refrigeration for controlled mirror cooling and stabilized dew point condensation detection. The DP29 series is engineered as a compact portable chassis with a dedicated measurement probe interface and built-in electronic sample gas flow monitoring for stable dew point humidity measurement. The AELAB DP29 includes instrument self-check functions for mirror check and cooling performance verification to support long-term measurement integrity.
The AELAB DP29 Chilled Mirror Dew Point Instrument performs chilled mirror dew point measurement by cooling a mirror surface until condensation forms at the dew point temperature. The instrument regulates mirror temperature using semiconductor refrigeration and detects the condensation equilibrium condition to measure dew point precisely. The AELAB DP29 stabilizes measurement using controlled inlet flow and inlet pressure conditions, then outputs dew point data through USB (default) or optional analog outputs for process integration.
The AELAB DP29 series includes three chilled mirror dew point instrument variants optimized for air dew point measurement, laboratory calibration reference, and SF6 gas dew point measurement.
