        OTT Pluvio² L – Weighing Rain Gauge

        All-weather, high accuracy rain gauge for continuous data collection

        The OTT Pluvio² L is an all-weather precipitation gauge that uses superior weight-based technology to measure the amount and intensity of rain, snow, and hail.

        • Cumulative precipitation, precipitation intensity, bucket content in real time and non real time
        • Weighing principle
        • All-weather precipitation gauge without moving parts according to WMO guide line No. 8
        • SDI-12 / RS-485, pulse

        OTT Pluvio² S

        Compact universal weighing precipitation gauge

        The OTT Pluvio² S compact weighing precipitation gauge measures liquid, solid and mixed precipitation with remarkable precision. It is virtually maintenance-free and fits on 2-inch pedestals.

        • Cumulative precipitation, precipitation intensity, bucket content in real time and non real time
        • Weighing principle
        • Compact all-weather precipitation gauge for 2-inch pedestals, highly accurate, meets WMO requirements (Guidelines No. 8), nearly maintenance-free, lifetime calibrated
        • SDI-12, RS-485, impulse, status

        OTT Parsivel² - Laser Weather Sensor

        Laser precipitation disdrometer measuring all precipitation types

        The OTT Parsivel² is a modern laser disdrometer for comprehensive measurement of all precipitation types. The Parsivel² captures both the size and speed of falling particles, classifying them into one of 32 separate size and velocity classes.

        • Precipitation type, intensity, drop size distribution, radar reflectivity
        • Laser optical
        • Simultaneous measurement of 32 classes for particle sizes and velocities
        • SDI-12 / RS-485, pulse

        Lufft WS100 Radar Precipitation Sensor / Smart Disdrometer

        Real-time measurement of precipitation type (Rain, snow, sleet, freezing rain, hail) and intensity, thanks to radar measurement technology. The absolutely maintenance-free smart radar rain sensor & present weather detector!

        The Lufft WS100 is a maintenance-free radar precipitation sensor. It recognizes the type and amount of precipitation from the first drop. The sensor is suitable for hard-to-reach places.

        • Rain/precipitation quantity, rain/precipitation type (Rain, snow, sleet, freezing rain, hail)
        • 24GHz Doppler radar
        • Very fast response time, maintenance-free measurement, present weather detection
        • RS-485 semi-duplex two-wire, SDI-12, pulse interface / UMB protocol, Modbus

        OTT TRH

        Weather sensor for humidity and temperature

        The digital weather sensor reliably measures the relative humidity and temperature. Equipped with a protective housing it can be used in a large variety of applications.

        • Air temperature and relative air humidity (measured), absolute air humidity, dewpoint and mixing ratio (calculated)
        • PT1000, capacitive
        • Low power draw, long-term stable, suitable for extreme temperatures, protective housing included
        • SDI-12 V1.3


        Ultrasonic Wind Sensor

        Thanks to the ultrasonic measuring method the wind sensor Lufft Ventus has no moving parts and therefore needs almost no maintenance. It measures wind speed and wind direction according to the WMO guideline and acquires the barometric pressure.

        • Wind speed, wind direction, virtual temperature, barometric pressure
        • Ultrasonic
        • Maintenance-free measurement, suitable for extreme ambient conditions, ice-free operation, vibration and seawater resistant, compatible interfaces
        • SDI-12, RS-485, various RS-485-protocols, analogue output
