The Sper Scientific 870003E Two-Wire Explosion-Proof Online Conductivity Analyzer supports continuous conductivity, salinity, TDS, resistivity and temperature monitoring with a compatible analog sensor.
The Sper Scientific 870003E 2-Wire Explosion-Proof Online Electrical Conductivity Analyzer provides continuous monitoring of conductivity, salinity, total dissolved solids (TDS), resistivity and temperature in water and process solutions.
Used with a compatible analog conductivity sensor, it is suitable for wastewater treatment, power generation, chemical processing, pharmaceutical manufacturing, food processing and drinking water applications. A two-wire 4–20 mA output connects the analyzer to process monitoring equipment, while low power consumption supports continuous operation in industrial installations.
Construction
The analyzer features a die-cast aluminum housing with an IP65 rating for protection against dust and water. Its construction supports use in demanding industrial environments.
