ZR-3500D multi-channel atmospheric sampler Introduction
The ZR-3500D multi-channel atmospheric sampler uses the solution absorption method to collect various harmful gases in the ambient atmosphere and indoor air. Eight samples can be collected simultaneously in one setting. Achieve full-scale unattended sampling. It can be used for environmental monitoring, sanitation, labor, safety supervision, military, scientific research, education and other departments for routine aerosol monitoring.
Executive standard
HJ/T 376-2007 24-hour constant temperature automatic continuous ambient air sampler technical requirements and testing methods
HJ/T 375-2007 Environmental air sampler technical requirements and testing methods
JJG956-2013 Atmospheric sampler verification procedure Features
The whole machine is excellent in waterproof, dustproof and anti-collision performance, which can guarantee the normal work of rain, snow, dust and heavy weather.
It adopts 5-inch color HD LCD touch screen and has button function, while supporting button and touch operation;
Built-in high-performance lithium battery, power supply time> 20 hours (normal temperature), can maintain normal sampling without external power supply;
Built-in 8-channel independent sampling module, which can realize 8-channel simultaneous sampling, all with check valves to prevent sample suction;
Compatible with a variety of absorption bottles;
The sampling pump controller has air circuit blocking and low flow protection;
The sampling flow rate and the sampling time are separately controlled, and constant current sampling, timing sampling, interval sampling, and 24-hour continuous sampling can be realized;
The incubator has a constant temperature function to ensure normal sampling in different environments;
High-precision, corrosion-resistant, high-humidity electronic flowmeters ensure high reliability and high sampling volume accuracy;
Support USB data export;
Ambient atmospheric pressure and temperature, measurable input;
Imported pressure sensor is used to avoid maintenance and calibration; the sampling process interrupts the automatic protection of electric data, and continues sampling after the call;
The telescopic sampling rod design can be happy and easy to operate;
Optional TSP sampling module;
Optional portable Bluetooth printer (with built-in lithium battery);
Optional GPRS communication module to remotely read device operating status information. Technical parameters
