LD-3F explosion-proof pocket computer laser dust meter

Explosion-proof pocket computer laser dust meter
Product description
.Product introduction:
The explosion-proof laser dust meter is a rapid dust measuring instrument that uses laser as the light source and meets intrinsic safety requirements. . The explosion-proof mark of this instrument is II and the explosion-proof certificate number is. This instrument can directly read the mass concentration (/). It is easy to carry and easy to operate. It can achieve rapid measurement of dust concentration in workplaces of Zone, Zone II Group and below. It is also suitable for detecting the concentration of respirable particulate matter in indoor and outdoor environments. .
The instrument complies with the standards of the Ministry of Health/-"Determination of Respirable Particles in the Air in Public Places-Light Scattering Method", the Ministry of Labor's "Light Scattering Method for Determination of Dust Concentration in the Air", and the Ministry of Railways-"Railway Workplaces" Industry standards such as "Conversion Method for Determining Relative Mass Concentration and Mass Concentration of Dust".
.Main features:
Can directly read the mass concentration of particulate matter (/) and produce results within minutes or set the sampling time arbitrarily according to user needs
Fast, accurate measurement, high detection sensitivity
Design The instrument performance of the self-calibration system is stable and reliable
It has air curtain shielding and clean gas self-cleaning functions to ensure that the optical system is not contaminated
It realizes automatic zeroing of the software
It has the function of two-way communication with the computer through The machine performs data processing and prints out curves and tables
It has multiple functions such as continuous monitoring of particle concentration, regular sampling, and alarms for excessive dust concentration
