Overview
The TR4A series enables data collection and management using dedicated mobile device applications.
Data recorded by the logger is sent to the mobile device via Bluetooth Low Energy, which can then be transferred to our free cloud-based "T&D WebStorage Service" using WiFi or cellular network.
The TR45 model is a versatile one channel temperature logger that can be connected to a Pt100 sensor or to a variety of thermocouple types (K, J, T, S, R). It is possible to measure and record temperature in a wide range from -199 to 1760°C.
Note: We carry Pt sensors as optional parts, but do not handle the sale of Thermoucouple sensors.
Special Features
The TR45 coupled with PT100/Thermocouple sensors is best suited to measure ultra high temperatures such as in a furnace or in deep freezers where temperatures reach ultra low levels.
We offer free mobile apps that let you access temperature data anytime from your smartphone or tablet over Bluetooth.
"T&D Thermo" facilitates logger configuration and data collection using a Bluetooth connection. The data retrieved by the mobile device can be viewed in a graph, saved, output as a PDF report, and uploaded to the cloud-based T&D WebStorage Service.
"TR4 Report" is a specialized mobile app for generating PDF reports for a specified time period. It allows you to create, print and share data reports in simple steps.
Note:
In addition to T&D Thermo and TR4 Report, the TR45 can still be used with the ThermoREC and ThermoStorage Apps.
