Product Description

The highly efficient RTR503B humidity and temperature wireless data logger from T&D offers flexible connectivity with an LCD display and interchangeable TR-3310 °C/rH sensor mounted on 1M of cable. This innovative logger delivers humidity and temperature data to the WSS online service when used in conjunction with an RTR500B base station.

This temperature and humidity sensor is small and compact, making it perfectly suited to applications where cloud based logging is required in tight spaces such as HVAC pipework or inside bottles held within incubators. It can be easily fixed into locations within an appliance or on a wall via the mounting hole.

Use the RTR503B humidity and temperature data logger with the designated base station via Bluetooth on any iOS or Android device, or USB for Windows PCs and laptops.

Use these wireless data loggers to create a cost effective network across your organisation, with flexible access options via LAN/WLAN/USB and even 4G GSM. This ensures that your data can be reliably retrieved and actioned regardless of existing I.T. infrastructure.

The RTR500B is supplied as standard with the TR-3310 humidity and temperature sensor and 3.6v user replaceable battery. It can be purchased with a long life battery upgrade or [PSU] external mains power adapter.
