EXO pH & ORP Smart Sensor

Measure pH and oxidation-reduction potential (ORP) in monitoring and sampling applications

The EXO pH & ORP Smart Sensor is a next-generation digital sensor designed to measure pH and oxidation-reduction potential (ORP) in monitoring and sampling applications.
The product is available in two versions:

  • Version 1: EXO pH & ORP Smart Sensor (Guarded) – optimized for durability, reducing the risk of physical damage and biological fouling.
  • Version 2: EXO pH & ORP Smart Sensor (Unguarded) – optimized for fast response time, designed for use with a central wiper.

  • pH Accuracy: ±0.1 pH units (within ±10 °C of calibration temperature)
  • ORP Accuracy: ±20 mV in Redox standard solution
  • Material: Welded titanium, corrosion-resistant
  • Wet-mateable Connector: Allows connection/replacement in wet conditions
  • Calibration: Fast calibration (<15 minutes) using Kor Software
  • Integrated Memory and Processor: Automatic recognition on any EXO Sonde port
  • Smart Ports: Automatically shut down excessive current draw to protect the sensor

Comparison of EXO pH & ORP Sensor Versions

Feature Guarded Unguarded
Application Designed for sampling applications in harsh environments; minimizes risk of impact damage and biological fouling Designed for use with EXO2 or EXO3 equipped with a central wiper; provides faster response
Installation Compatibility Not compatible with EXO2/EXO3 when a central wiper is installed Specifically designed for EXO2/EXO3 with a central wiper
Electrode Protection Protective guard prevents mechanical damage No guard, allowing direct exposure to sample
Accuracy High, ideal for stable monitoring applications Fast response with high accuracy
Maintenance Less prone to damage, longer service life Easy maintenance with automatic cleaning from central wiper

Compatibility with EXO Sondes

  • EXO1 Sonde — Compact design with 4 ports
  • EXO2 Sonde — 7-port, high-capacity multiparameter monitoring
  • EXO3 Sonde — 5-port, cost-effective solution
  • EXO1s, EXO2s, EXO3s Sondes — Same features as EXO1/EXO2/EXO3, but without battery compartment; designed for fixed-site monitoring
