The SMP series instruments are high quality radiometers designed for measuring short-wave irradiance on a plane surface (radiant flux, W/m²), which results from the sum of the direct solar radiation and the di use sky radiation incident from the hemisphere above the instrument.
SMP pyranometers feature internal digital signal processing and interfaces optimised for industrial data acquisition and control systems. Kipp & Zonen has developed a smart interface that features RS-485 Modbus data communication for connection to programmable logic controllers (PLC’s), inverters, digital control equipment and the latest generation of data loggers. Amplified Voltage or Current outputs are also included for devices that have high-level analogue inputs or current loop interfaces.
All models are available in two versions. One has an analogue voltage output of 0 to 1 V, the other has an analogue current output of 4 to 20 mA. They all have a 2-wire RS-485 interface with Modbus (RTU) protocol. Digital signal processing provides faster response times and, with an integrated temperature sensor, corrects for the temperature dependence of the detector sensitivity.
To achieve the required spectral and directional characteristics SMP Series pyranometers use thermopile detectors and glass domes. All SMP’s have built-in bubble levels and adjustable levelling feet. Snap-on sun shields reduce solar heating of the housings. The waterproof connectors have gold-plated contacts.
The pyranometers are normally delivered with a waterproof plug pre-wired to a high quality signal cable, typically this is 10m long but other lengths are available. The instruments can also be ordered without a cable or with a plug only, for the user to fit their own cable.

Applied Research and Innovative Solutions: Creating CHNGES at Western Kentucky University
Long-standing environmental monitoring programs have the power to support a large number of research initiatives and policy changes—however, actually starting these networks can prove challenging. Not only is starting the program difficult, but keeping things operational for decades to come has also been challenging for environmental professionals hoping to make an impact with applied research. Jason Polk, Professor of Environmental Geoscience and Director of the Center for Human GeoEnvironmental Studies (CHNGES) at Western Kentucky University, is all too familiar with this process.

Combating Water Insecurity in Saskatchewan with Real-Time Data
The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.

Seametrics Turbo Turbidity Logger: Boost your Turbidity Monitoring
The Seametrics Turbo Turbidity Logger is a self-cleaning turbidity sensor capable of internally logging over 260,000 data records. The sensor enables researchers, compliance officers, and contractors to monitor turbidity in various applications, from construction and dredging sites to wastewater effluent. Due to its narrow width, this device can be deployed in a range of areas, from small well spaces to rivers and streams. The stainless steel housing and built-in wiper allow the sensor to withstand long-term deployments and reduce the need for maintenance trips. The logger accurately records temperature and turbidity up to a depth of 50 meters.
