Real-time dust alarm The main technical features of the concentration detector are a replaceable particle cutter, which is compatible with a variety of particle separation cutters.
An online filter membrane sampler is designed to realize continuous monitoring of dust concentration and filter membrane sampling. Compatible, the components of the collected particulate matter can be analyzed and the mass concentration conversion coefficient value of the place can be calculated.
Using a laser light source, the mass concentration conversion coefficient is not affected by the color of the particulate matter.
Using large-screen LCD Chinese characters The display realizes Chinese character menu prompts.
A constant current controller is designed to ensure constant sampling flow and correct cutting curve.
There is a built-in optical standard loose plate to ensure high stability of the instrument.
There is a special protective air curtain to avoid dust contamination of the optical system of the core components of the instrument, ensuring high reliability of the instrument.
Automatic zero-point adjustment of the instrument is realized through computer software, which improves the measurement accuracy of the instrument and facilitates user use.< br/>The instrument is designed with a timing sampling mechanism, which can sample regularly according to the set time, start and shut down regularly, and the data obtained can be recorded through a micro printer or imported into the machine for data processing, making the instrument suitable for continuous monitoring of respirable particulate matter in the atmospheric environment.
The device can set the alarm threshold for dust concentration exceeding the standard, automatically sound and light alarm when the dust exceeds the standard, or transmit the signal to the control center for monitoring.
The device is designed with an analog output interface to evaluate the air purifier When the purification efficiency evaluation curve is drawn, the purification efficiency evaluation curve can be drawn.
In addition to the general measurement mode suitable for dust monitoring in indoor public places and the scheduled sampling mode suitable for atmospheric environment monitoring, a new labor hygiene mode is added. In this mode, according to According to the hygiene standards of industrial enterprises and the exposure limit standards for harmful factors in the workplace, the time-weighted average and the allowable concentration of short-term exposure are calculated.

Online and transmission functions
Electric Restart function: When the power supply is restored to the instrument, it can automatically enter the measurement state
Electrical protection function: The set parameters and measurement results of the instrument will not be lost in the event of a long-term power outage. The time synchronization function can synchronize the clock of the monitoring instrument through the wireless transmission network. Time synchronization.
Multi-center software function
This system software can work online or offline. When online, by monitoring the dust meter node on the bus, any dust on the bus can be collected in real time Functions such as instrument data, uploading historical records, and curve drawing can be used to query records, draw historical curves, calculate concentration values, and other functions when offline. The agreed functional terms are as follows
Organizing the bus, the total number of supported instrument addresses is Taiwan.
Collect real-time data from dust monitoring instruments.
Manage the collected data, including real-time drawing and historical data drawing, storage and query, and printing.
Managing the device nodes on the bus allows the center to configure the parameters of the device. Every time the communication device exceeds one or the cumulative communication distance exceeds meters, a relay station needs to be added.
Alarm if the temperature exceeds the standard.
Automatic and manual control (dust suppression equipment) command output (optional).
Prepare fault log records.
Upload data according to settings (communication protocol to be determined) (all upload exceeds the standard [concentration value can be set] data upload.)
Conversion of temperature value (determined by input data, set value, humidity, weather conditions Concentration value)
Automatically receive the data transmitted from the dust meter and display it in the display box. The data can also be displayed intuitively in the form of a curve graph.
Query historical data, the query results are displayed in the display box, or the data can be displayed intuitively in the form of a curve chart.
The environmental monitoring equipment can be equipped with two types of gas sensors and particulate matter monitoring equipment to form a portable monitoring substation. The first choice for gas sensors is domestic manufacturers that have many years of cooperation with our company and many years of sensor production experience. The advantages are timely supply, rich experience, and after-sales service guaranteed by professional and technical personnel. The particulate matter monitoring equipment uses our company's products, with a range of Seriously, most of them focus on monitoring dust.
