Key benefits

Easy to install and relocate

Wireless communication utilizes existing Wi-Fi network and is ideal for facilities without available wired infrastructure and for applications in which measurement points move regularly.

Internal data storage

Onboard memory stores data during a power outage or network downtime so no data is ever lost ensuring gap-free records. The logger’s history is always transmitted to the viewLinc monitoring system once communication is restored.

Interchangeable temperature/RH probes for easy field calibration

The HMP110 digital humidity and temperature probe is field replaceable and contains all calibration details. Monitoring system viewLinc's event log will record any sensor swap-outs, ensuring your audit trail is complete and compliant.
