The Model SRS-DF14MHTE heavy duty hand truck mounted mobile low volume air sampler with digital flowmeter and an adjustable, aluminum sampling gooseneck. The adjustable gooseneck permits sampling at heights varying from 4’ to 7’ above floor level. Model SRS-DF14MHTE contains state of the art microprocessor electronics, which provides for corrected flow rate measurements, volume totalizations, and an RS232 communications port. It has a large bright LED display. A card mounted filter holder is included with the unit.
The SRS-DE14MHTE is designed for continuous indoor use. Please consult the product specifications for the design operating temperature range and installation category
The SRS-DF14MHTE Air Sampler includes an oil-less, carbon vane vacuum pump with a constant airflow regulator for use where a nearly constant airflow is desirable. The regulator holds a constant pressure drop across an in-line orifice by varying the flow through a bypass valve into the pump. This system allows the pump to work at a minimum pressure drop at all times, permitting it to run cooler, thus extending its lifetime. The oil-less pump requires no lubrication to maintain optimal efficiency during its service life. The pump is mounted on a rugged hand truck with two 10.5” diameter pneumatic tires to facilitate mobile transportation of the unit.
The typical operating flow range is 0.5 to 4 CFM (14 to 115 LPM).
