The TR4 series with low energy Bluetooth 4.0 guarantees easy temperature monitoring. Without pre-registration, loggers within the communication range are instantly detected and automatically refreshed by mobile devices. Records can be monitored and stored in the free of charge, cloud-based T&D WebStorage Service with two dedicated apps.
The TR4 series comprises three competitively priced models with different sensor types and measurement ranges to serve diverse application requirements. TR41 covers temperature measurements from -40 to 80°C (internal sensor, IP67). TR42 measures from -60 to 155°C (external sensor, IP64). TR45 for industrial use is available for thermocouple types K, J, T, S, R covering -199 to 1.760°C or for types Pt 100/Pt 1000 with a range of between -199 and 600°C.
The real-time monitoring of automatically collected data is managed by the ThermoRec app, displayed in easy-to-read graphs or in measured value views, while the ThermoStorage app accomplishes one-step uploading and sharing via the cloud. Simultaneous data collection from multiple loggers is possible. Each logger can be set to 15 different recording intervals, from one second to 60 minutes. Thanks to the T&D WebStorage Service, a cloud with 20 MB storage capacity per account, it is possible to view and analyse up to 160000 current readings in one graph.
Their high precision and wide range measurement abilities combined with their flexibility makes the TR4 series ideal for multiple tasks. Application examples include heating control in housing or agricultural sites, safeguarding of refrigerators, sales cabinets and storage facilities as well as supervising transportation of sensitive goods.
