The Integrating Water Sampler IWS III is a light and handy instrument for the acquisition of summing (integrated) water samples according to the EU-WFD (European Water Framework Directive). The integrated sample is automatically achieved in one single draft. There is no need for repeated operations of standard water samplers, followed by mixing procedures.
The sampling technique is very simple. An electric motor actuates a piston inside a transparent tube. A microprocessor controls the sampling procedure according to the pre-selected depth, time or spot scenario. A built-in high precision pressure sensor cares for accurate depth measurements. Power supply of the sampler is made by rechargeable lithium-ion batteries, using the safest chemistry currently available.
