Odalog L2

The Odalog sensor is used to measure the sulphuretted hydrogen (H2S) concentration in sewage works or systems. A version with a 4-20 mA output is available for situations in which continuous value measurement is required.

The sensor is protected against ambient humidity and has an IP66/IP68 protection rating. The recorder can store up to 42,000 values, with recording intervals ranging from 1 second to 1 hour.

The sensor operates as a standalone unit, and its lithium batteries are sufficient for 8 months’ operation.

The instantaneous value is displayed on an LCD screen, and a 4-20 mA output, to a remote management system, is available as an option. The sensor communicates with a PC through an infra-red communication system. The sensor is precisely calibrated every 6 months, in relation to reference solutions.
