Product Description

Description:

    The pHionics STs Series™ ORP is a low maintenance, 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.

 

Highlighted Features:

• Replaceable electrode with platinum sensing element measuring -1000 to +1000 mV oxidationreduction potential (ORP)

• 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 insertion down pipes or boreholes

• Low power usage

 

Applications：

• Groundwater Monitoring

    o Agricultural Runoff

    o Mining Pollution

• Industrial Effluent Monitoring

• Wastewater Treatment

• Environmental Remediation

• Aquaculture
