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 con fi gurable to meet all sampling needs by combining a controller, base, bottle set, accessories and sampling program features. 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 fl ow, aport 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.

Easiest and most intuitive operation The large full color display and intuitive programming give you access to all your programmable criteria on a single screen - eliminating scrolling through menus and supporting error-free operation. Most convenient data transfer and programming available The AS950 is the only sampler that utilizes a USB drive to upload and download data and copy programs from one sampler to another. Con fi dence in your sampling process The program status screen instantly communicates alarms, missed samples and program progress for quick and easy troubleshooting. Resists corrosion The All-Weather Refrigerated (AWR) sampler base is designed to endure humid and highly corrosive environments, minimizing damage caused by corrosive gases, rodents, and standing water to guarantee environmental integrity. Accurate and consistent sample preservations The custom-designed air-sensing thermostat controls temperature in accordance with USEPA and international guidelines, preserving samples regardless of outside temperatures and conditions.
