TFH 620 + TPH 100 Hygrothermometer - Xylem Analytics EBRO
The PTFE-filter 100 provides little protection from mechanical strain but seals the probe from dust - protection class IP 60. In dusty environments, unprotected humidity probes, or probes protected by sintered fi lters, can quickly be covered by dust. This massively affects the humidity measurement, or prohibits it entirely.
