AS950 All Weather Sampler (AWRS)

Sampling has never been this easy!

The Hach AS950 AWRS is a robust, weather resistant field sampler with an integrated refrigerator, for applications where temperature control is required for sample preservation. The custom designed air sensing thermostat controls temperature in accordance with USEPA and international guidelines, preserving samples regardless of outside temperatures and conditions.

Complete with a large, full-colour display, the Hach AS950 Portable Sampler can be programmed without the need for a field laptop. It offers USB upload & download capabilities, and the ability to copy programs between samplers.

For stormwater sampling, the Hach AS950 portable sampler provides the ability to initiate up to two different programs based on user-defined conditions, such as rainfall or pH thresholds.

For industrial sampling, the Hach AS950 portable sampler is available with a non-contact liquid detect to prevent cross contamination of samples.

The Hach AS950 can be further programmed to collect varying sample sizes, collect samples at user-specified time intervals (i.e., time-weighted) or flow volume increments (i.e., flow-weighted), or collect samples over an entire run-off event as determined by a rain or flow sensor. Sample tubing can be replaced quickly without tools.

Various models are available.

Please discuss with Aqualab before ordering.

FEATURES

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.

Confidence 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.
