The AS950 refrigerated sampler is optimised for indoor applications that require temperature control to preserve samples. Every AS950 includes a peristaltic pump with spring-loaded rollers and a standard liquid detection sensor for best-in-class sample volume accuracy. A USB connection and an auxiliary port for pulse or 4-20 inputs are also standard. Factory-installed options include sensor ports for integrated Hach water quality, level or flow, a port for MODBUS RS485 communication, or a rain gauge and an alternative non-contact liquid detection sensor. Finally, inputs and outputs can be expanded with the IO9001 for a single high-voltage relay and the IO9004 for a comprehensive set of analog and digital inputs, outputs and relays. The refrigerated sampler base is available with a black vinyl or stainless steel finish.
