Hach AS950 Automatic Samplers collect and store unbiased representative water samples for laboratory analysis. AS950 automatic samplers are available in three base types: portable, indoor refrigerated, and all-weather refrigerated, and are compatible with a variety of bottle sets of varying size, quantity, and material. The AS950 is configurable to meet all sampling needs by combining a controller, a base, a bottle set, accessories and sampling program features.
Hach’s latest automatic sampler controller, the AS950, makes programming, data transfer and operation more intuitive and virtually error-free.
Every AS950 is equipped with a peristaltic pump with spring-mounted rollers that provide long tubing life and a standard liquid detect sensor for best-in-class sample volume accuracy. Additionally, the USB connection and an auxiliary port for pulse or 4-20 inputs are standard. Factory-installed options include sensor ports for integrated Hach water quality, level or flow, a port for MODBUS RS485 communication or a rain sensor and an alternate non-contact liquid detect sensor. Finally, inputs and outputs can be extended using the IO9001 for a single high-voltage relay or the IO9004 for a comprehensive set of analog and digital outputs and relays. The AS950 is fully configurable and the links below take you to lists of the most popular pre-configured combinations.

The AS950 Sampler controller replaces legacy SD900 and 900MAX sampler controllers.
