Hach Announces First Luminescent Sensor For Process PPB Level Oxygen Monitoring

Loveland, CO — Hach Company announces the availability of the G1100 Trace Oxygen Sensor, the first sensor for ppb level oxygen monitoring using proven Luminescent Dissolved Oxygen (LDO) technology. Designed to meet maximum reliability and minimum maintenance requirements, the G1100 offers distinct advantages over DO sensors with traditional chemical cells including:

• Dry sensor with no membrane
  No electrolyte, chemicals, or complex service procedures required.

• Automatic on-line calibration
  High accuracy with minimal operator time needed.

• Real time diagnostics
  Notification of due service, need for calibration sample replacement, calibration failure, sensor or system failure provided.

• Minimal service
  Service requirements limited to just 5 minutes every 18 months. Oxygen levels do not affect service intervals.

The G1100 provides a detection limit of 0.01 ppb and measures DO in the range of 0-20,000 ppb. Applications in the power plant water and steam cycles include monitoring the stator coolant, condensate, deaerator, and feedwater for corrosion control.
