Explosion-Proof Online pH/ORP Analyzer


Share this Product

The Sper Scientific Explosion-Proof Online pH/ORP Analyzer supports continuous pH or ORP and temperature monitoring with a compatible analog electrode.

The Sper Scientific 870002E monitors pH or oxidation-reduction potential (ORP) in industrial water and process solutions. Its online design provides continuous readings, helping operators track changing conditions throughout a process.

Connect a compatible analog pH or ORP sensor to measure the selected parameter along with temperature. The analyzer sends a 4–20 mA signal to connected monitoring equipment, allowing readings to be incorporated into a plant’s process monitoring system.

The 870002E is suited to applications such as wastewater treatment, drinking water processing, chemical production and power generation. Its explosion-proof design and low power consumption support use in industrial environments.

Features

  • Continuous online monitoring of pH or ORP and temperature
  • Analog sensor compatibility for the selected measurement
  • Two-wire 4–20 mA output for connection to monitoring equipment
  • Explosion-proof design for suitable industrial applications
  • Low power consumption for continuous operation
