Product Description
Description：
The pHionics STs Series™ pH is a dual-output sensor that pairs with a datalogger or RTU for real-time water quality monitoring. A narrow diameter allows the STs Series to go where other sensors cannot while a durable, chemical-resistant housing ensures many years in-use.
All parts, including the cable, are easily replaceable without tools using pHionics patented pHiConn™ System, saving frustration and money.
In addition, isolation, differential amplification, and shielding ensure a strong signal with high signal-noise ratios, all while remaining low-power.
These features make our pH sensor well-suited for applications such as groundwater monitoring, wastewater treatment, aquaculture, pollution monitoring, etc.
Highlighted Features：
• Combination double-junction electrode measuring 0 to 14 pH
• Large reference half-cell to reduce calibration frequency
• Secondary 0-50°C temperature sensor
• 2-wire, 4-20 mA analog outputs compatible with wide range of dataloggers or remote telemetry units (RTU)
• Narrow diameter (0.75 inches or 1.9 cm) for groundwater monitoring applications
• Low power usage
Applications：
• Groundwater Monitoring
o Agricultural Runoff
o Mining Pollution
• Industrial Effluent Monitoring
• Wastewater Treatment
• Ballast Monitoring
• Environmental Remediation
• Aquaculture
