The BAPI Blu-Test Temperature and Humidity Probe G2 (BA/BT-TH) is an 8-inch NIST-traceable wireless test probe for temperature and humidity with ±0.36°F temperature accuracy — 2 to 10 times more accurate than typical HVAC handheld meters. Communicates via Bluetooth LE to the free Blu-Test App. Stores up to one million readings at 10-second intervals.
Best for: HVAC commissioning and sensor verification requiring simultaneous NIST-traceable wireless temperature and humidity reference measurements. The BA/BT-TH is the benchmark probe for verifying BAPI-Stat Quantum and other wireless room sensors.
Backed by BAPI's 5-year warranty. Important: Do not get the temp/humidity probe tip wet. The humidity sensing element is not waterproof. If liquid contacts the tip, remove immediately with a paper towel and dry with a warm blower.
Keep the Probe Tip Dry
The humidity sensing element in the BA/BT-TH probe tip is not waterproof. Do not expose to liquids, high-pressure spray, or condensation-soaked environments. If liquid contacts the probe tip, remove it immediately and dry with a warm blower before use.
±0.36°F Temperature Accuracy
2 to 10 times more accurate than typical HVAC handheld instruments. NIST-traceable calibration certificate included. Annual recertification available: BA/BT-TH-RECERT.
±1% RH Humidity Accuracy
Humidity accuracy of ±1% RH at 77°F from 10 to 85% RH. Combined with temperature accuracy of ±0.36°F, the BA/BT-TH is the definitive HVAC commissioning reference for both measurements simultaneously.
Free Blu-Test App
Live readings from up to 6 probes on one screen. Trend logging, CSV email export for commissioning documentation. OLED display shows readings without the app.
Up to 1 Million Readings
Logs at 10-second intervals in up to 31 log files. Double-press to start/stop logging. Rechargeable battery runs up to 10 days continuous.
