1. Program background:

Guangxi Nanning odor online monitoring project, Nanning factory workshop and district environmental testing of a certain environmental protection technology group Co., Ltd.

2. Parameter requirements:

According to the national standard "Emission Standards for Odorous Pollutants (GB14554-1993)", nine indicators for controlling odorous substances, including odor (ammonia, trimethylamine, hydrogen sulfide, methyl thiol, methyl sulfide, dimethyl sulfur, disulfide Carbon, styrene, stench).

Requirements:

with sound and light alarm; industrial-grade high-precisition touch screen, displaying the current concentration value, maximum value, minimum value, 1 minute and 1 hour average, and can select historical data query for any period of time, curve display; built-in large-capacity memory chip, can store 10 More than 10,000 pieces of data, and exported through special interface data; the chassis adopts outdoor special nano-protection coating technology, which is resistant to sun and rain, heat insulation, anti-mosquito and insect-proof, and can be used outdoors for a long time; compatible with TCP/IP, MODBUS, DTU and other communication protocols, which can not only wireless data upload and connect to the local environment Baobu or cloud platform, you can also have a wired long-distance network

two sets in the workshop and two sets in the factory

3. Solution:

The parameter configuration is recommended as follows:

Detection gas: H2S (hydrogen sulfide), NH3 (ammonia), C3H9N (trimethylamine), CH4S (methyl thiol), C2SH6 (methyl sulfide), C2H6S2 (dimethyl disulfide), C 8H8 (styrene), CS2 (carbon disulfide), OU

H2S: detection range 0-100ppm, resolution 0.01ppm

NH3: detection range 0-100ppm, resolution 0.01ppm

C3H9N: detection range 0-20ppm, resolution 0.001ppm

CH4S: measurement range 0-20ppm, resolution 0.001ppm

C2SH6: Measurement range 0-20ppm, resolution 0.001ppm

C2H6S2: Measurement range 0-20ppm, resolution 0.001ppm

C8H8: measurement range 0-2 0ppm, resolution 0.001ppm

CS2: measurement range 0-20ppm, resolution 0.001ppm

OU: measurement range 0-2000, resolution 1
