The Spectra Technologies 2825 Series portable\dedicated automatic water sampler is the next generation in water sampling technology. An advanced refrigeration and heating system is incorporated into the design of the unit. This configuration allows the user to use the sampler year around. Sample when outdoor temperatures are below freezing, no more hauling ice when the weather is warm. The 2800 Series can be left in place when ambient air temperature ranges from -25o F to 122oF. An automated heating and cooling system monitors environmental temperatures and will select the proper cooling or heating system that is required to maintain sample integrity. A pump\electronics compartment heater maintains proper operating temperature as well as prevents the internal pump tubing from freezing. This fully programmable unit allows the user to select from a list of sampling methods including time based, flow based, level based or rain gauge-based options.

Customer Testimonial
The biggest issue we have had with portable samplers is hauling ice every day or two to remote locations. Weekends were a big problem. The Spectra 2800 is the best solution for this problem. The refrigeration unit keeps our samples at specified temperature, even on the hottest days.
