Fast response from our specialists

The TR72A allows you to measure and record temperature from 0 to 55°C and humidity from 10 to 95%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 not only homes and offices but for warehouse and storage facilities.

TR-72A

Benefit

The TR72A uses a wireless LAN access point to auto-upload recorded data and warning notifications to our free cloud-based "T&D WebStorage Service". Use our 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 our Windows software “TR7 for Windows”. Our Windows software “T&D Graph” makes it easy to view and analyze data from your PC.

TR-72A-S

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.

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.

The TR72A-S uses a wireless LAN access point to auto-upload recorded data and warning notifications to our free cloud-based "T&D WebStorage Service". Use our 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 our Windows software “TR7 for Windows”. Our Windows software “T&D Graph” makes it easy to view and analyze data from your PC.

*1: We do not handle the sale of Thermocouple sensors. Compatible wire sizes are as follows.

Single Wire : 0.32 to 0.65 (AWG 28 - 22),Twisted Wire : 0.08 to 0.32 (AWG 28 - 22),0.12 or more in diameter, Stripping Length : 9 to 10

*2: When Auto Upload is used frequently, the measurement of the internal sensor may rise by around 0.3°C.

When using external power, the data logger itself generates heat and the internal sensor will report a temperature much higher than ambient; we recommend using an external temperature sensor in this case.

*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.

*4: Vaccine mode complies with the CDC (Centers for Disease Control and Prevention) requirements for vaccine management.

*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.

The specifications listed above are subject to change without notice.
