ZR-3950 ambient air organic sampler Introduction
ZR-3950 ambient air organic sampler is mainly used to collect polycyclic aromatic hydrocarbons, pyridines, organic pesticides, chlorinated benzenes, quinolines, nitrobenzenes, polychlorinated biphenyls, etc. in ambient air. Volatile Organic Compound (SVOC) samples are also suitable for sampling dioxin components in ambient air such as waste incineration power plants.

GBT 15439-1995 "Environmental air benzo[a]pyrene determination by high performance liquid chromatography
HJ 77.2-2008 Ambient Air and Exhaust Gas Determination of Dioxins Isotope Dilution High Resolution Gas Chromatography-High Resolution Mass Spectrometry
HJ/691-2014 Guidelines for the Measurement of Environmental Air Semi-Volatile Organic Compounds (SVOCS) Features
Simultaneously collecting VOCS and SVOCS of particulate physical, gaseous and aerosol states present in ambient air;
Split design, special aluminum alloy and borosilicate glass adsorbent sleeve, easy to disassemble and transport;
The sleeve is sealed and protected from light during the whole process before and after sampling to prevent adsorbent contamination and sample evaporation loss;
The flow range covers large flow (225L/min), large flow (800L/min), and benzopyrene sampling flow (1130L/min);
Excellent heat dissipation performance, no thermal protection when the ambient temperature is too high;
Adopt imported brushless fan, automatic constant current sampling, strong load capacity and low noise;
Built-in GPRS module to remotely view the sampling status and sampling data of the instrument.
Built-in Bluetooth module, optional Bluetooth printer for data printing;
Small size, light weight, foldable bracket;
It has two sampling functions by volume and time, and supports timing sampling and immediate sampling.
Professional structure design, with rain and dust proof function, can work in rain and snow weather, dusty environment;
Digital measurement, automatic calculation of cumulative volume and standard volume;
Automatically measure and display ambient temperature, humidity, atmospheric pressure and other parameters, optional wind speed and direction sensor;
Overload automatic protection function, when the instrument sampling abnormal situation, stop protection;
The call restart function, power down during the sampling process, continue sampling after power-on, and record the power-down data;
High-brightness color touch screen, wide temperature work, easy operation and good human-computer interaction;
Built-in large-capacity memory, long-term storage of sampled data and power-down data;
Data export and program upgrade can be performed through U disk. Technical parameters
