Its longer 1 meter PVC lead lets you position the sensor probe down to nearly 80 cm, while the integrated LCD shows live values on site. Wireless transmission uses Ecowitt gateways or select display consoles (sold separately) to upload data to the Ecowitt app for monitoring, logging and alerts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the WH51L differ from the standard WH51?\u003c\/h3\u003e\n\u003cp\u003eWH51L adds an on-device LCD and a longer 1m cable for deeper measurements; its probe housing is rated to a higher waterproof standard.
