The result is a highly reliable and cost effective design with easy-to-use user interface. The analyzer comes with a 0 - 1,000 PPM full scale low range. A removable USB flash drive for data logging via .CSV (Excel) file format. With an 8GB USB Flash Drive, you can data log at 1 minute intervals for about 50 years before running out of storage. The low full scale range and flexibility to easily access data allows this analyzer to be unmatched in the market. The display of the analyzer is designed to be used in direct sunlight. No need to bring a shade or other method to see the screen. The oxygen sensor used in the OMD-640 is based on the galvanic electrochemical fuel cell principal. All oxygen sensors are manufactured in house by Southland Sensing Ltd. under a strict quality program. The standard cell (TO2-133) is unaffected by other background gases such as H2, He or Hydrocarbons. The acidic cell (TO2-233) works well when acid gases such as CO2 or Natural Gas are present. The sensors are self-contained and minimal maintenance is required no need to clean electrodes or add electrolyte.
