AS950 Peristaltic Samplers

AS950 Peristaltic Samplers
Sampling has never been this easy.

Hach AS950 Automatic Samplers collect and store representative water samples for lab analysis. AS950 samplers are available in three bases: portable, indoor refrigerated, and all-weather refrigerated and are compatible with bottle sets of varying size, quantity, and material. The AS950 is configurable to meet all sampling needs by combining a controller, base, bottle set, accessories and sampling program features.

Hach’s automatic sampler controller, the AS950, makes programming, data transfer and operation intuitive and virtually error-free.
• A large colour display and intuitive programming give access to programming criteria on a single screen, eliminating scrolling through menus and supporting error-free operation.
• USB drive compatibility provides convenient data transfer and allows quick copying of programs from one sampler to another.
• The status screen instantly communicates alarms, missed samples and program progress for quick troubleshooting and confidence in the sampling process.

Every AS950 is equipped with a peristaltic pump with spring-mounted rollers providing long tubing life and a liquid detect sensor for best-in-class volume accuracy, a USB connection and an auxiliary port for pulse or 4-20 inputs. Factory-installed options include sensor ports for Hach water quality, level or flow, a port for Modbus RS485 communication or rain sensor and an alternate non-contact liquid detect sensor. Finally, inputs and outputs can be extended with the IO9001 for a single high-voltage relay or the IO9004 for a comprehensive set of analog and digital outputs and relays.

The AS950 samplers are the successor items for the SD900 peristaltic samplers.
