Temperature and Humidity Data Logger with a High Precision Sensor
- TandD - TR72A-S
- To measure and record with high precision temperature from -25 to 70°C and humidity from 0 to 99%RH.
Access Temperature and Humidity Data Measured with a High Precision Sensor Anytime from Anywhere
High precision IoT temperature and humidity logger connectible via wireless LAN, Bluetooth and USB!
The TR72A-S allows you to measure and record with high precision temperature from -25 to 70°C and humidity from 0 to 99%RH.
The LCD screen allows the simultaneous display of either the current values of two channels, the highest and lowest values of channel 1, or the highest and lowest values of channel 2. The ALM icon on the LCD alerts the user of the occurrence of an alarm.
Use the wireless LAN feature to auto-upload data to the cloud for anytime anywhere access and get warning notices. Bluetooth communication allows you to view data, create reports and make settings from a smartphone or tablet. Connect to a PC with a USB cable to download recorded data, create reports and make setting changes.
It is perfect for situations where strict temperature and humidity control is required, such as when storing delicate items or in testing using constant temperature and humidity chambers.
Features
The TR72A-S uses a wireless LAN access point to auto-upload recorded data and warning notifications to T&D free cloud-based "T&D WebStorage Service". Use T&D mobile app “T&D Thermo” to check data from your smartphone or tablet and use Bluetooth communication to make settings, download recorded data, and create reports. To make settings from and download data via USB to a PC, use T&D Windows software “TR7 for Windows”. T&D Windows software “T&D Graph” makes it easy to view and analyze data from your PC.

*3: When continually used in environments with temperatures above 60 °C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20 °C.
*5: Client function. HTTP(S) proxy supported.
*6: Battery life in the table above is for two AA Alkaline type batteries, and varies depending upon multiple factors including frequency of communication, network environment, ambient temperature, recording interval, and battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
