HF scientific

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)
