Product Introduction

This instrument is an explosion-proof high-performance comprehensive dust sampler. It has the advantages of small size, light weight, beautiful portability, simple operation, and long battery life. Adopting imported ultra quiet reciprocating diaphragm pump, it easily maintains a constant flow within the range of (3-25) L/min, with advantages such as low noise, high vacuum degree, and long service life. Equipped with various measuring accessories, it makes sampling easy and effortless. The use of imported electronic flow meters ensures high accuracy and minimal interference, guaranteeing high precision in data collection. Suitable for fixed-point sampling of dust, metals, fluorides and other dust substances that pose occupational hazards in the workplace.

Product Features

Constant voltage and constant current: closed-loop control, flow rate is not affected by voltage fluctuations and air resistance changes.

APP control: The instrument automatically and intelligently monitors time, progress, and battery level.

Traffic self calibration: With open calibration permissions, users have precise control over the accuracy of each sampled traffic.

Multiple protection: The whole machine has automatic protection functions such as overvoltage, overcurrent, and overheating.

Low noise: The machine adopts a low-noise diaphragm pump and is equipped with shockproof function. The normal working noise is below 55dB (A).

Highlight advantages

Personalized design: Adopting a stable and durable design concept, low noise, portable use, unique appearance, and easy operation.

Constant voltage and constant current: Imported electronic diaphragm pump, supplemented by closed-loop control technology, the flow rate is not affected by voltage fluctuations and gas resistance changes, and can easily maintain constant current within the range of (3-25) L/min.

Support self calibration: Built in precision electronic flowmeter, users can calibrate flow under different loads. Ensure the authenticity and reliable quality of each sampling flow.
