Product Introduction

The EM-1000/EM-1500 (explosion-proof) fixed-point toxic substance sampler is an innovative sampler with 21 patented technologies developed specifically for sampling PC-TWA and PC-STEL toxic substances in the workplace air. The instrument has excellent performance of continuous constant current and intelligent power saving. Personalized combination kits can achieve the collection of multiple factors at the same sampling point. Simultaneously equipped with temperature and pressure measurement function, it can accurately and conveniently provide standard volume information. Suitable for fixed-point toxic sampling of occupational hazards in the workplace, as well as individual sampling of dust substances such as metals and fluorides.

Product Features

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

Two stage buffering: The patented two-stage buffering effectively reduces the damage of steam and particulate matter to the motor.

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

Combination application: Multiple combination sampling applications can be achieved through combination brackets or individual accessories.

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

Temperature and pressure measurement: Automatically measure the microclimate at sampling points and provide information on entities, standards, etc.

Highlight advantages

Super Load Capacity: The EM-1 500 has a maximum load capacity of over 30kPa, reaching an international leading level. It is particularly suitable for sampling high flow and high load substances such as acrylonitrile and hydrazine.

Two stage buffering: The patented two-stage buffering device can effectively reduce the damage of steam and particulate matter to the motor.

Diverse changes: The instrument is equipped with various combination kits, which facilitate absorption method or adsorption tube combination sampling, and can also be used for individual sampling of dust compounds. Users achieve ultimate changes between splitting and grouping.

Temperature and pressure measurement: The instrument is equipped with a high-precision temperature and pressure sensor, which automatically measures the microclimate of the sampling point and provides information such as cumulative volume and standard condition volume.
