Description

Handheld Probe for Measuring Bulk Packaged Materials

The insertion probe is suitable for measurement in bulk materials, bricks, concrete, etc. It measures humidity and temperature and calculates the dew/frost point.

Applications
10 mm insertion probe: measurements in dusty bulk materials such as flour, sugar, etc.

Features
• Range of application: -40…85 °C / 0…100 %rh
• Digital interface (UART) and scalable analog outputs, 0…1 V
• Standard output scaling: 0…1 V = -40…60 °C / 0…100 %rh
• Adjusted at 23 °C and 10, 35, 80 %rh
