SD900 All Weather Refrigerated Sampler


Unsurpassed Corrosion resistance
With American Sigma´s All-Weather Refrigerated Sampler, spending time and money to maintain your sampler is a thing of the past. We designed this unit to last longer than any other sampler available. First, we put the compressor on top to avoid hydrogen sulfide and other corrosive heavier-than-air gases, which attack conventional refrigerated samplers with floor-level compressors. Then, we equipped the sampler with a tough, chemically resistant coating to better protect refrigeration lines against moisture and corrosive gases. Finally, we used stainless steel hardware, sealed electrical connections and weather resistant cables to complete its corrosion-resistant design.

Mother Nature Meets Her Match
Customers quickly learn that the name All Weather is no exaggeration. This sampler is designed to operate anywhere - indoors or out - without a secondary enclosure. The Controller compartment heater keeps pump tubing clear of ice in sub zero temperatures. Completely self-contained, the All Weather is rated for operation in temperatures from -40° to 120°F. The cabinet is linear low density polyethylene with rounded, moisture-shedding, UV-resistant surfaces. Its sidewall ventilation system allows positioning against a wall, and its sturdy locks prevent tampering. Leveling feet and anchor brackets ensure proper, secure installation.
