Overview
Overview
The WS300-J is an all-in-one weather sensor measuring air temperature, air pressure, and relative humidity. A drop-in replacement for the Lufft WS300, the WS300-J is an updated model built on the same trusted Lufft platform, reporting data every 5 seconds instead of every minute. It features a streamlined design for flexible integration into existing networks, a new aspirated radiation shield, and integrated self-diagnostics. Built for Air Quality and Meteorological Observation, the WS300-J delivers core environmental data without paying for additional parameters. Now you can measure more, maintain less with the WS300-J.
Benefits
Focused Atmospheric Measurements
The WS300-J delivers accurate air temperature, air pressure and relative humidity data with output rates of 5s. An external tipping bucket or surface/ module temperature sensor can be connected. Its streamlined design provides the essential measurements needed for climatological monitoring, forecasting, and environmental observations.Reduced Risk, Improved Self-Diagnostics
The WS-J's incorporates improved house-keeping functions, live heating-voltage monitoring, and automatic self-diagnostics to catch a failing component before it corrupts the rest of the instrument and finally your decision-making data set.Flexible Integration into Existing Networks
The WS300-J is a perfect match when a low power device is required and when air temperature & humidity must be measured at 2 m height, while wind with a WS200-J measured at 10 m height. The new aspirated radiation solution ensures lifetime performance and the single sensor. One station, one data stream, and seamless integration into established monitoring networks.One Platform Across Networks
The J-Series is a drop-in replacement for legacy WS units, sharing size, weight, mounting, cable connections, available protocol formats and interfaces, and software across the platform. One calibration reference, one spare pool, one standard.Specifications
