The sampling module is common to all models in the Aysix-Aquacell Wastewater Sampler range. The module employs a wide bore air pump vacuum sampling system to automatically collect representative and repeatable effluent samples at very precise volumes. Straightforward to program, operate and maintain. The air pump vacuum sampling system provides for a reliable, representative and repeatable sample without the weaknesses that can be associated with alternative sampling techniques. Programming set-up is simple, with sample volumes from 50 – 500ml (and above) and sample intervals from 1 minute to almost 100 hours. Sample extraction can be time based or triggered by external sources such as flow meters, level sensors, pH meters, PLC’s etc.
