Product Description

The TR-75NW is a battery powered data logger compatible with a wide range of thermocouple temperature sensors. It is supplied with built-in USB and RJ45 LAN sockets that enable users to connect directly to a USB port or an existing Ethernet network.

This battery or mains powered data logger displays, collects and stores temperature data measured by one or two interchangeable temperature sensors (Not supplied). Historical data can be extracted to a PC using the integral USB connector or linked in real-time data via the LAN module to a mobile device running iOS, Android or that hosts an internet connection and browser.

Boasts a large LCD display that rotates between the last temperature reading recorded by probe 1 and probe 2, along with the recording, network and battery status.

Connect your T&D temperature data logger to an application specific temperature probe, for example our PR11 probe is ideally suited for use at extreme temperatures (Liquid Nitrogen and ovens) Add multiple data loggers until all your monitoring points have been covered and then monitor your data and alarm conditions from a central location via the T&D cloud utility called ‘Webstorage-service’.

Unlike alternatives offered by Loggershop and our competitors, T&D deliver free application and cloud storage utilities with no contracts or restrictions. Traditionally costs associated with these centralised cloud services is invoiced monthly or annually and should always be considered when calculating the T&D data logger cost of ownership versus any other alternative networked solution.
