Description

The compact and automated Testo 164 H1 mini online data logger is a specialized stationary instrument fitted with integrated temperature and humidity sensors. As a core component of the advanced Testo 160 ecosystem, this device tracks environmental microclimates and streams them via a secure, proprietary wireless sub-1 GHz connection directly to the gateway for central testo Smart Connect cloud storage. Featuring an ultra-small profile housing certified with an IP20 rating and an embedded high-performance battery providing an operational lifecycle of up to 8 years, it ensures completely maintenance-free tracking. When configured boundary values are exceeded, real-time push alerts, automated emails, or SMS alarms are transmitted instantly via the smart network system framework.
