SENSOREX
Frequently asked questions
Common questions about SENSOREX from 3G Electric.
What is the difference between single-junction and double-junction Sensorex pH electrodes?
Single-junction electrodes, like the Sensorex S200C/STD, have one reference junction that can become clogged or contaminated in dirty or chemically aggressive samples. Double-junction electrodes, such as the S200CD/BNC or S267CD, incorporate a second junction that isolates the reference electrolyte from the sample, reducing contamination and extending electrode life. Double-junction designs are recommended for applications involving heavy metals, sulfides, or low-ionic-strength solutions.
Which Sensorex pH sensor kit is suitable for surface or flat-surface measurements?
The Sensorex S8300/10/BNC and S8300TC/10/BNC/TL sensor kits feature a flat tip shape, making them appropriate for measuring pH on flat surfaces, such as in food processing (e.g., cheese, meat) or on moist solids. These kits include a double junction and a Ryton PPS body, with a 3.05 m cable and BNC or tinned leads connection. The flat tip allows direct contact with the sample without needing immersion.
What is the measurement range of the Sensorex S8100-ORP/10/TL ORP sensor?
The Sensorex S8100-ORP/10/TL measures ORP from -1999 to 1999 mV. It features a flat tip shape, a double junction, and a Ryton PPS body, with a 3.05 m cable terminated with tinned leads. This sensor is designed for continuous monitoring of oxidation-reduction potential in industrial processes, such as wastewater disinfection or chemical reaction control.
Can the Sensorex DO1200/T dissolved oxygen sensor be used in wastewater treatment?
Yes, the Sensorex DO1200/T is suitable for dissolved oxygen measurement in wastewater treatment applications. It has a measurement range of 0 to 20 mg/L and is constructed from Noryl material, which offers chemical resistance and durability in aeration basins and effluent monitoring. The sensor uses tinned leads for connection and is designed for submersion in water or wastewater.
What cable lengths are available for Sensorex pH electrodes and sensors?
Sensorex pH electrodes and sensors are commonly available with cable lengths of 0.76 m (e.g., S200CD/BNC, S200C/STD) or 3.05 m (e.g., S267CD, S265CD, S8300/10/BNC). The 0.76 m cables are typical for laboratory benchtop use, while the 3.05 m cables provide flexibility for installation in tanks or remote locations. Connection types include BNC, tinned leads, or standard connectors.
What body materials are used in Sensorex pH electrodes and how do they affect performance?
Sensorex pH electrodes use either epoxy or Ryton PPS (polyphenylene sulfide) body materials. Epoxy bodies, found in models like the S200CD/BNC, are economical and suitable for general laboratory use but may degrade in high-temperature or aggressive chemical environments. Ryton PPS bodies, used in the S267CD and S8300 series, offer superior chemical resistance and thermal stability, making them appropriate for industrial processes with harsh conditions.
