Key Features
- Robust: Inert construction will not corrode in high salinity samples; Insensitive to common interferences such as hydrogen sulfide, chloride, chlorine, ammonium, and many others
- Cost effective options: Choose models for use with the economical LD500 Local Display; providing 4-20mA outputs and various communications protocols; Choose models available with integral 4-20 mA, Modbus RS-485, and SDI-12 outputs for direct connection to SCADA or PLC; totally eliminating the need for a separate transmitter/controller
- No calibration hassles: When used with the LD500 Local Display, no calibration is required; When connected directly to a SCADA or PLC, a one-time calibration is performed that lasts for 12 months
- Low maintenance: No electrolyte or membranes to replace; Sensor cap lasts 1 year without the need for recalibrations; Simply wipe the sensor cap periodically. Optional air blast accessory available
- Accurate: 0.1 mg/L accuracy from 0 – 8 mg/L DO, and 0.2 mg/L accuracy from 8 to 20 mg/L DO; Fast response to oxygen and temperature changes; Consistent, reproducible results (<0.05 mg/L reproducibility)
