Overview
The Hach Intellical PHC745 is a digital combination pH electrode with built-in temperature sensor. The PHC745 is a pH refillable electrode with a reverse sleeve reference junction embedding the RedRod technology to deliver exceptionally fast, stable, and accurate response times for accurate measurements within a wide temperature range. A 59-mL bottle of saturated KCl Electrode Filling Solution is included with the probe.
Applications
Thanks to its easy-to-clean and high-flow reverse sleeve reference junction, this high-performance laboratory glass pH electrode is ideal for measuring pH in samples prone to clogging traditional reference junctions such as wastewater influents, emulsions and viscous liquids. The PHC745 is not suitable for use with organic solvents or high-alkaline sample types.
Accessories Included: None
Minimum Sample Depth (mm): 18

Floating Global New Ideas: Buoy-Enabled Research at Florida Agricultural and Mechanical University’s School of the Environment
Florida Agricultural and Mechanical University (FAMU), based in Tallahassee, Florida, is the highest-rated public Historically Black College or University in the United States. FAMU’s School of the Environment (FAMU-SOE) offers BS and BA degrees in Environmental Studies, and BS, MS, and Ph.D. degrees in Environmental Science, with specialisms available in areas including Environmental Policy and Risk Management, Aquatic and Terrestrial Ecology, and Biomolecular Sciences. In 2021, FAMU-SOE deployed a NexSens CB-450 buoy in Apalachee Bay, a key oyster farming area around 30 miles south of Tallahassee. The buoy has quickly been incorporated into the curriculum, providing environmental insights for student research, the community, and beyond. Dr.

Monitoring Habitat Suitability and Water Quality in Northwest Arkansas Springs
Northwest Arkansas has seen an economic, industrial, and population boom in recent years as a result of expanding businesses, which have created thousands of jobs in the region and the mass migration of employees and construction companies. However, with this growth has come rapid urbanization and the degradation of the natural landscape, specifically the freshwater springs that can be found throughout the region. These springs are critical habitat centers for native wildlife, home to threatened and endangered fish, and those that have yet to be listed. Zach Moran, Assistant Professor of Fisheries Science at Arkansas Technical University, is working to help monitor these habitats and provide key data that will hopefully inform future development in the region.

Three Decades of Research at Acton Lake
A multi-disciplinary team at Miami University, Ohio, has been studying the environmental change at Acton Lake for over three decades. Using three different NexSens buoys over this time, the team has an incredible archive of data that is helping build a picture of Acton’s past, present, and future. Until recently, a NexSens CB-50 buoy was used alongside other environmental monitoring at Acton Lake. In May 2025, the Miami team deployed a new XB-200 buoy , future-proofing their ongoing monitoring using real-time buoy systems. Acton Lake, a small hypereutrophic reservoir in southwest Ohio, covers 2.4km² and has a maximum depth of about 8m. The dam was built in 1956, and the lake has a large agricultural watershed.
