testo 350 &ndash; The testo 350 Process Kit is a base kit designed for special processes or uncommon industrial and commercial combustion applications. It contains the minimum required parts and allows for an unlimited choice of sensors, probes, and hardware upgrades. It&rsquo;s our go-to kit when you need a special or customer configuration. Examples of such testing kits are for:<br />
<br />
&bull; Continuous CO2 and O2 monitoring&nbsp;<br />
&bull; High concentration (up to 400,000 ppm) monitoring of NOX, SO2, H2S, or CO.<br />
&bull; Special combustion R &amp; D projects (i.e., catalysts, fuels development, combustion/flame assessment)<br />
&bull; Semi continuous monitoring using remote access (Modbus or analog output)&nbsp;<br />
<br />
A variety of hardware choices like precision valves that allow for programable automatic data logging programs, long-life sample pumps. Data connection cables that can exceed 1000&rsquo;s of feet, or BT connection to over three hundred feet away. &nbsp; This analyzer is truly remarkable.&nbsp;<br />
Contact us with your ideas and we will configure the analyzer for your application.&nbsp;
