Product Description

The product conforms to Q / wth 10-2016 th-2001b ammonia analyzer; GB 3095-2012 ambient air quality standard; HJ 654-2013 technical requirements and detection methods for continuous automatic monitoring system of ambient air gaseous pollutants (SO2, NO2, O3, CO).

Features

The core and analysis principle of th-2001b is exactly the same as th-2001. That is to say, the principle of chemiluminescence spectroscopy is used to integrate the optical, mechanical, electrical, photochemical and modern sensing technologies. The signal is detected, processed, controlled and transmitted by the electronic microcomputer technology, and the trace NH 3 content in the ambient air can be continuously and automatically monitored. Different from th-2001, the sample gas inlet of th-2001b is equipped with two channels of sample gas inlet and gas path switching device controlled by new software, one of which is used for online acquisition

Th-2000h outputs conversion sample gas, one of which is used to directly collect ambient air sample. Th-2001b adopts a dual channel single channel time-sharing sampling gas path system, which reduces the measurement error caused by the rapid change of no concentration in the stable environment of NO2. Compared with the traditional dual channel and dual channel simultaneous sampling gas path system, the dual channel single channel time-sharing sampling system only uses one reaction chamber and one PMT detector, which simplifies the system structure and improves the reliability of the system. The hardware principle of the instrument is basically the same as th-2001, and the NH3 detection and analysis interface is added in the software. The whole machine adopts modular design, with parameter setting, historical data storage and

Automatic calibration, alarm prompt, upper computer communication and other functions.


Scope Of Application

Th-2001b ammonia analyzer is a dual task analyzer based on th-2001 chemiluminescence nitrogen oxide analyzer. Th-2001b and th-2000h thermal oxidation furnace can be used for ammonia (NH 3) analysis and single unit operation can be used for NO x analysis. As a detection unit of the ambient air automatic monitoring system, the instrument is combined with other analyzers to form a local automatic monitoring sub station system. The collected data is transmitted to the upper computer of the sub station through the RS-485 serial communication port. The upper computer of the sub station collects the data of the analyzers and transmits the data to the regional central station through the cable modulation and demodulation transmission mode. On the one hand, the collected data is remotely transmitted to the regional central station, on the other hand, a series of instructions (such as automatic calibration) from the regional central station are received to automatically monitor the operation status of the instrument. The automatic monitoring network of ambient air is composed of several sub station systems, so that the environmental monitoring department can quickly and timely grasp the air quality of the area.
