Handheld dust detector for energy new material workshop

Overview:Handheld dust detector for energy new material workshop

JYB-6A Handheld Dust Detector is a dust detector independently developed by Shenzhen Juyibo Company. It is a direct reading dust detector mainly used for detecting the concentration of dust particles (TSP, PM10, PM2.5) in industrial and mining enterprises and issuing alarms for exceeding the standard. Using the principle of light scattering and semiconductor laser as the measurement light source, high-sensitivity non-contact measurement of dust in the air is carried out. The entire testing process is managed and controlled by a single-chip microprocessor, using a high-resolution large screen high brightness LCD display with full Chinese language display.

Instrument execution standard:

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.

Usage scenario:Handheld dust detector for energy new material workshop
1. Measurement of dust concentration in industrial sites

2. Monitoring of dust concentration at exhaust outlet

3. Occupational health, health and quarantine monitoring

4. Test respiratory equipment or air filtration efficiency

5. Testing powders in scientific research, filter performance testing, and other aspects

6. Detect the air environment quality, dust concentration in workplaces, transportation vehicles, and other places, and identify the concentration of dust transmitted in the air.

Technical principle:

JYB-6A handheld laser inhalable dust continuous detector adopts the principle of light scattering and uses semiconductor laser as the measurement light source. The light scattering method is designed to absorb and digest the dust measurement technology. Infrared laser and imported photomultiplier tube are used to irradiate the floating dust entering the darkroom with infrared laser. Under certain dust properties, the scattered light intensity of the dust is proportional to the dust mass concentration. The scattered light intensity is converted into an electrical signal, and the mass concentration of the dust can be directly calculated by presetting the K value. The entire testing process is managed and controlled by a single-chip microprocessor, and high-definition, high brightness LCD displays are used to display detection data in Chinese.

Fault and Exception Handling:

· Reading drift/inaccuracy: Clean the sensor and optical window first, and recalibrate; If it is still abnormal, check whether the sensor is aging, whether the air path is blocked, and replace the sensor if necessary.

· Unable to power on/abnormal power on: Check battery level, charging interface, and power adapter; Clean the battery contacts, but still cannot solve the problem. Contact the manufacturer for maintenance.

· Air path blockage/abnormal flow: Clean or replace the filter, blow the air path; Continuous abnormal flow requires maintenance of the sampling pump.

· Self disassembly is strictly prohibited: The internal structure is precise, and non professional disassembly can easily damage sensors and circuits. In case of malfunction, contact the manufacturer or maintenance agency.
