The MC-623 Source Sampling Console (MC-623) is applicable for U.S. EPA Methods 4, 6, 11, 18, 26, VOST, and Methods 0030 and 0031. It can be used for any method requiring accurate volume measurement of low sample rates, typically 0.3 to 4 liters per minute. The console features a small lightweight dry gas meter fitted with an optical encoder and resetable digital volume totalizer. The internal diaphragm pump is corrosion resistant and rated for up to 6 liters per minute free flow. The gas meter temperature, and up to five remote temperatures, are measured with Type-K thermocouples and displayed with a digital temperature display (LED). Three digital temperature controllers are standard for accurately maintaining probe and filter temperatures and auxiliary heater temperature (when applicable). The source sampler console is housed in a sturdy lightweight vented aluminum cabinet featuring all stainless steel hardware and three carrying handles. The console is easily serviced by simply unlatching the front panel latches and sliding out the chassis, allowing full access to all components. Standard with all stainless steel fittings and quick connects.
