Detection Instruments OdaLog L2 Hydrogen Sulfide Gas Logger (0 – 1000 PPM)

Key Features
  • Purpose designed for harsh wastewater environments
  • Longer battery life
  • Simplifies record management
  • Easy to read display
  • Faster downloading
  • Certified intrinsically safe

The OdaLog L2 was designed specifically for the wastewater industry, based on valuable input and feedback from plants, equipment and chemical suppliers and industry consultants Typical applications include locating and monitoring the source of Hydrogen Sulfide gas emissions at pump and lift stations, collection systems, and receiving manholes. Once the source of the odor is determined, the OdaLog L2 can be used to prove the effectiveness of hydrogen sulfide reduction strategies that have been implemented. OdaLog customers cost-justify instruments through chemical savings realized by determining the specific times that the H2S emissions occur.

The OdaLog L2 is small, robust, and capable of extensive data logging. Double O-rings minimize moisture ingress and water damage to the instrument’s electronics. Magnetic switches for zeroing and calibrating and an infrared communications link eliminate outside pin connections and associated corrosion problems. The OdaStat-G Software is used for programming the L2 OdaLog, as well as for downloading the data after completing a logging session. The L2 uses a single lithium battery that lasts up to 12 months, has increased memory capacity, uses a single screw design for simple and effective assembly/disassembly and uses IrDA communication protocol for faster downloading.
