The AGENT 1: RLD15B Refrigerant Detector is designed and certified to meet the new tougher standards and detects the latest refrigerants. Equipped with a heated sensor to increases accuracy and reduce false alarms, the Agent 1 displays approximate leak sizes with the digital leak size indicator to help pin-point leak sources. Finally the true mechanical pump draws gas over the sensor faster providing a quick response in a variety of contaminated or windy environments.
