Dewpoint Meter

The Vaisala Indigo80 is a robust handheld indicator and data logger for industrial spot checks, process diagnostics, field calibration and measurement data analysis.

• Connect and display measurements from up to two compatible probes
• Measure humidity, temperature, dew point, carbon dioxide and other industrial parameters
• Use with HMP80, DMP80 and GMP80P portable measurement probes
• Record up to approximately 5.5 million real-time measurement values

The Vaisala DM70 was a portable meter for dew-point spot checks, process measurements and data logging. It is discontinued and replaced for general dew-point work by the Vaisala Indigo80 handheld indicator with a DMP80A or DMP80B probe.

• Legacy DMP74A, DMP74B and SF₆-specific DMP74C probe options
• Direct or sampled measurement in pressurised processes
• Portable numerical and graphical display with data logging
• Current replacement: Indigo80 with DMP80A or DMP80B
• DMP80A for moderate dew points down to −40 °C Td/f
• DMP80B for dry applications down to −70 °C Td/f
