Features
The WN38 Black Globe Thermometer measures and displays the black globe temperature only, which can be viewed on the LCD screen or through the Ecowitt or WS View Plus app.
To display WBGT (Wet Bulb Globe Temperature) data in the app, the WN38 must be used together with an Ecowitt outdoor temperature and humidity sensor from either an outdoor array or a WN32(WN31 is not feasible).
The collected data can be transmitted via an Ecowitt Wi-Fi Gateway or displayed on a compatible receiver console(both sold separately). Once Wi-Fi configuration is completed, data can be viewed in real time through the Ecowitt app, WS View Plus app, or on the receiver console.
