OdaLog® Low Range H2S Logger

The OdaLog Low Range H2S Logger is a high sensitivity, convenient, weather resistant, and portable instrument designed to assist in H2S odor management activities by accurately measuring concentrations of H2S much lower than the standard range of OdaLog H2S Loggers. With a range of 0.01 to 2.00ppm, the OdaLog Low Range H2S Logger allows reliable measurement of H2S based odours at plant fence-lines, scrubber outlets, land fill sites, and residential locations where odour complaints have been reported.

Typically the OdaLog Low Range H2S Logger may be placed at the outlet of a scrubber for performance tracking or several units may be mounted on a fence line or plant perimeter for the purpose of measuring concentrations of H2S leaving a facility and entering adjoining properties.

Data can be logged at sampling intervals of between 10 minutes and one hour. The recorded H2S data can be downloaded to a computer using the standard OdaLog infrared link and OdaLog software. Detailed information on the OdaLog software can be found on the OdaLog Low Range H2S Logger website at http://www.odalog.com/OL_Software.htm

An internal battery (1 x standard C size Alkaline cell) will operate the built-in sampling system continuously for at least seven days and a separate internal Lithium cell powers the main processor functions for at least two months.
