LB-ZXF online dust detector

Introduction

The LB-ZXF online dust detector is a new type of microcomputer laser dust detector with advanced technology in the new century. It can continuously monitor dust concentration and collect particulate matter for analysis of its composition. Directly readable dust mass concentration (mg/m3), with PM10, PPM2.5 or TSP

The instrument complies with the hygiene standards for industrial enterprises (GBZ1-2002), exposure limits for harmful factors in the workplace (GBZ2-2002), the Ministry of Health's WS/T206-2001 "Method for determination of inhalable particulate matter (PM10) in the air of public places - light scattering method" standard, the Ministry of Labor's LD98-1996 "Method for determination of dust concentration in the air by light scattering method" standard, TB/T2323-92 "Method for determination of relative mass concentration and conversion of mass concentration of dust in the air of railway workplaces" and other industry standards, as well as the Ministry of Health's "Hygienic Specification for Central Air Conditioning and Ventilation Systems in Public Places" document [2003] No. 225.

Main functional features and technical indicators:

It can simultaneously measure PM2.5, PM10, or TSP, using excellent multi-channel electronic cutting technology without the need to replace the cutting head;

Measurement range: 0.001~10mg/m ³;

Relative measurement error: ≤± 10%; Detection sensitivity: 0.001mg/m ³;

◆ With over limit alarm function, the alarm value can be set arbitrarily;

◆ Can detect and measure the temperature and humidity of the environment;

◆ With curve display function: measuring and drawing data curves at the same time, users can directly observe the trend of dust concentration changes through the curves;

◆ With statistical analysis function: the instrument can automatically calculate the average concentration and high concentration during the measurement period, and can query the occurrence time of peak concentration;

◆ Large screen LCD Chinese display, user-friendly design, rich display content, LCD with backlight display;

◆ Equipped with a built-in real-time clock, the measurement data is stored with time, making it convenient for users to conduct statistics and analysis;

Sampling time: Users can freely set the measurement cycle for each set of data within 0-99 minutes, and can preset 10 sets of sampling times;

◆ Data storage capacity: There are 100 storage areas, each of which can store 1000 measurement records, with a total capacity of 100000 measurement records. The stored data can be saved for at least ten years without loss during power outages;

◆ Can be paired with a micro printer to directly print measurement data anytime, anywhere;

Measurement data can be transmitted to a computer for statistical analysis through software;

◆ Working power supply: built-in battery, dual-use for AC and DC; Imported lithium battery cells can measure continuously for 12 hours when the built-in battery is fully charged;

Communication method: Digital signal: RS232, RS485; Analog signal (optional): 4~20ma, 0~5V;

◆ Host volume: 400mm × 300 mm × 170 mm; Host weight: 1000g;
