Key features

• •1. This sampling pump is an accessory specifically developed for AS89 series gas detectors, It helps the gas detector detect gas concentraion of narrow or complicated environments,air flow velocity is about 0.5 cubic inches per hour,maximun gas sample collecting distance is about 50 inches,providing higher sensitivity for the detector effective.
• •2. It is used combine with Smart Senaor AS89 series gas monitor, such as AS8900, AS8901, AS8902, AS8903A, AS8904, AS8905, AS8906, AS8907, AS8908...etc
• •3. It does not operate independently,it needs to work with the voltage from the AS89 series gas detectors.Therefore,the sampling pump must be connected to the detector with 2 screws,please do not connect any other voltage power supply to the sampling pump to avoid burn out the pump.
• •4. When you are using the sampling pump,please ensure tighten up the sampling pump to the AS89 series gas detector with 2 closed type screws,avoiding poor contact .
