pHionics ORP & Temp 1000

The pHionics STs Series™ ORP sensor (sonde) provides reliable ORP and measurements to monitor bacterial activity, sanitization, or heavy metal pollution.  This sensor may be connected to an RX station using an an Analog Mote and HOBOnet Manager (wireless) or an Analog Module (wired).Accurate and low-maintenance operation is ensured with noise-resistant 4-20 mA analog signals and a large-volume, double-junction electrode.  Typical electrode life is 2-4 years and, when needed, a replacement is easily installed thanks to pHionics’ patented pHiConn™ Connector System.  In addition, the electronics are isolated to prevent ground loops and proprietary signal conditioning virtually eliminates background noise.Durability is guaranteed with chemical-resistant 316 Stainless Steel (titanium optional) and high-quality double O-ring seals that last many years, even in harsh conditions.  When combined with the compact design (0.75 in. or 19 mm diameter), this ORP sensor proves to be compatible with a wide range of applications including aquaculture, environmental monitoring, and pollution control.If you need a sensor that works anytime, anywhere, for many years, then the pHionics STs Series ORP sensor is here for you.

• Low Maintenance
• The weak point of ORP sensors is their reference solution, which gets diluted by the sample over time.  STs Series ORP sensors mitigate this problem by incorporating a reference half cell with a large reservoir.  The high volume, combined with a low-flow reference gel and junction, reduces the dilution rate to provide stable measurements with less calibration.
