Remote planktonic bacteria sampler with display screen flow

Abstract

The utility model relates to the technical field of samplers, and particularly discloses a remote planktonic bacteria sampler with a display screen flow, which comprises a main body shell, a fan is arranged in the main body shell, a Venturi tube is arranged in the main body shell, and the fan is communicated with the Venturi tube through a connector; the device further comprises a sampling head, a plurality of sampling holes are formed in the sampling head, and the sampling head is communicated with the end, away from the fan, of the Venturi tube through a connecting unit. The fan is communicated with the sampling head through the venturi tube and the connecting unit, the air is exhausted through the exhaust unit while the sampling operation is completed, and the air circulation is realized, so that the working requirement of the planktonic bacteria sampler is met, and in the process, the venturi tube utilizes the unique structure and venturi effect of the venturi tube, and the sampling efficiency is improved. And the air flow can be accurately measured and controlled. The Venturi tube differential pressure flowmeter is combined with the high-precision differential pressure sensor, so that the sampling flow can be monitored and calibrated in real time.
