# UNI-T UT363 Wind Speed and Temperature Meter vs REED R4000SD Data Logging Vane Thermo-Anemometer: specs and price compared

A sourced, side-by-side comparison of the UNI-T UT363 Wind Speed and Temperature Meter (UNI-T) and REED R4000SD Data Logging Vane Thermo-Anemometer (REED Instruments) among anemometers.

## Side by side

| Spec | UNI-T UT363 Wind Speed and Temperature Meter | REED R4000SD Data Logging Vane Thermo-Anemometer |
| --- | --- | --- |
| US price | not published | not published |
| Brand | UNI-T | REED Instruments |
| Wind speed range ms | 0 to 30 m/s | 0.4 to 30 m/s (79-5906 ft/min) |
| Airflow cfm cmm | — | — |
| Velocity accuracy | ±(5% of reading + 0.5 digit) | ±(2% of reading + 0.2 m/s / 40 ft/min) |
| Sensor type | Fixed rotating-vane head, typical of the UT36x series (not explicitly named on the manufacturer spec sheet) | Rotating vane, 72mm (2.8 in.) diameter, low-friction ball bearing |
| Temperature range | -10 to 50 °C (14 to 122 °F), ±2 °C / ±4 °F accuracy | 0 to 50 °C (32 to 122 °F) ambient probe; optional Type K (-100 to 1300 °C) / Type J (-100 to 1200 °C) thermocouple input |
| Data hold logging | Data hold only; no onboard logging (the separate UT363BT variant adds Bluetooth transmission to the iENV app, still no SD storage) | Onboard SD-card datalogging up to 16GB, adjustable 1-3600 sec sampling interval |
| Backlit display | Yes | Yes |
