American Weigh BlueTag TH30R-I data logger

The BlueTag TH30R-I is a rechargeable Bluetooth hygrometer with two external probes for temperature and humidity monitoring. It suits users who need to record conditions in refrigerators, greenhouses, laboratories or cold-chain logistics. The device pairs with the free Tkeeper app on Android or iOS for configuration, live viewing and report export without opening the monitored space. Buyers who require Wi-Fi connectivity or a built-in display for standalone reading should look elsewhere.

Bluetooth range and probe limits

Wireless range reaches 150 ft in open space, so thick walls or metal enclosures will reduce reliable distance. The internal sensor covers -30°C to +70°C and 0% to 95% RH with ±0.3°C and ±3% RH accuracy. The dedicated temperature probe spans -80°C to +200°C with accuracy of ±0.2°C from +14°C to +104°C, ±0.5°C from -40°C to +212°C and ±0.9°C outside those bands. The combined temperature-humidity probe handles -40°C to +85°C and 0% to 95% RH at ±0.3°C and ±3% RH. Memory stores 20,000 readings per probe.

First-time setup and common issues

Insert each probe into the logger before powering on, then download the Tkeeper app and pair via Bluetooth by scanning the QR code or entering the ID manually. Logging interval can be set from 1 min to 99 min and start delay from 0 min to 72 h. Up to six high/low alarm points per probe are user-configurable. Data syncs automatically to the cloud when the app connects; reports export as PDF or CSV with optional signature and calibration certificate. Forgetting to plug in a probe before starting is the most frequent setup error.

Questions about this item

Should I use the single temperature probe or the combined temperature and humidity probe for my fridge?

The temperature-only probe reaches -80°C to +200°C with ±0.2°C accuracy between 14°C and 104°C. The T&H probe covers -40°C to +85°C and 0–95% RH with ±0.3°C and ±3% RH accuracy. Choose based on whether you need humidity data and the temperature range required.

What does the ±0.3°C internal accuracy mean when the logger is sitting on a shelf?

The internal sensor is rated ±0.3°C full scale across -30°C to +70°C. In a typical fridge at 4°C the reading will stay within 0.3°C of the true temperature. External probes give tighter accuracy in their specified ranges.

How far can the Bluetooth signal reach through a freezer door?

Open-space range is 150 ft. A freezer door and walls will reduce that distance. The logger stores up to 20,000 readings per probe locally, so data is not lost if the phone is temporarily out of range. Data syncs automatically when the Tkeeper APP reconnects via Bluetooth.
