DOL 51 Ammonia Sensor for Air Cleaning

DOL 51 Ammonia Sensor for Air Cleaning

DOL 51 is an ammonia sensor specially designed for continuous measurement of ammonia (NH3) concentrations in high-humidity environments, extending the capabilities of the award-winning sensor. DOL 53.

Works in harsh conditions

DOL 51's innovative design allows it to operate in harsh conditions with extremely high humidity of 95% - 100%, such as livestock houses. Air is directed to the measuring inlet through a heated tube that prevents condensation. Like all dol-sensors products, DOL 51 is thoroughly tested and offers a long service life without calibration.

Accurate ammonia measurements

DOL 51 provides accurate ammonia measurements at concentrations up to 50 parts per million and has minimal cross-sensitivity to other gases. DOL 51 is installed directly in the airflow without any tubes or pumps.

Ensure air cleaners work efficiently

DOL 51 measures residual ammonia concentrations after air passes through the filters on the clean-gas side of air cleaners. These data are vital for documenting exhaust-air cleanliness.

Combined with DOL 53 data from the air-cleaner inlet, DOL 51 data can ensure air cleaners operate as efficiently as possible at the lowest possible additive cost.
