Product Introduction

This instrument is a 5L/min constant current individual dust sampler developed to follow the trend of individual sampling in occupational health monitoring. Broad spectrum flow can also be effectively applied for fixed-point sampling of substances such as ozone, acrylamide, TDI, MDI, etc. It can also be used for individual sampling of dust toxins such as metals and fluorides. Suitable for individual sampling of dust, metals, fluorides and other dust substances that pose occupational hazards in the workplace, as well as fixed-point sampling of substances such as ozone and TDI.

Product Features

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

Ultra long battery life: The instrument can work continuously for 12 hours with a load of 5kPa at 1L/min using polymer lithium batteries.

Traffic self calibration: With open calibration permissions, users can control the accuracy of each sampled traffic and can have automatic calibration.

Tri fixed sampling: timing, constant volume, and constant time interval form the tri fixed sampling mode, making PC-TWA easier.

Intelligent sampling: The instrument intelligently monitors time, progress, and battery level, and can shut down at scheduled times.

Highlight advantages

Dual use of dust and toxin: A broad-spectrum flow rate of (1-5) L/min can be used for individual sampling of dust, metals, fluorides, and other dust chemical factors. It can also take into account the fixed-point sampling of toxins such as TDI.

Ultra high load: Within the commonly used flow range of 1L/min, there is a load of over 20kPa, and even PTFE membranes can easily maintain constant flow.

Ultra long battery life: The instrument is intelligent and energy-saving, equipped with high-energy polymer lithium batteries, and can work continuously for more than 12 hours under a load of 5kPa at 1L/min.
