AIR QUALITY ANALYZERS
ENVIRA has been official technical support of Met One Instruments products for Spain, Portugal and Andorra since 1998.
Met One Instruments is a leading company in research, development and manufacturing of meteorological instruments, particle monitoring and environmental software. The particle monitors made by Met One Instruments have been designed to offer maximum precision when measuring suspended particles in accordance with the requirements of environmental monitoring.
The BAM 1020 model automatically measures and registers the concentration of particles by measuring the attenuation of beta radiation. It is the first equipment with these characteristics that has been certified by the United States Environmental Protection Agency (EPA). It has a European certificate for the equivalent measurement method.
It is a real time beta attenuation particle monitor, similar to the EPA methods for class III in the US. It provides accurate measurements of PM10 or PM2.5 in real time. The system can be placed permanently on roofs, near roads, at industrial sites, or it can be set up quickly in case of emergency. Designed for work in hostile environments without additional protection.
E-SAMPLER is a dual technology instrument combining real-time measuring by means of a laser dispersion technique and a gravimetric filter method. Its filters can be extracted and replaced in less than a minute. The filter medium can be selected depending on the kind of analysis that will be chosen later. The ambient temperature and the barometric pressure are measured to provide a flow in current conditions.
The BC 1054 model is a multispectral analyzer that measures light transmittance through a filter medium where particles are deposited in real time, thus calculating the concentration of black carbon with 2 different wavelengths, from almost UV to IR. It can be connected to a wide variety of products through the BAM 1020 or through several meteorological sensors.
The BC 1050 model is an analyzer that continuously measures light transmittance through a filter medium where particles are deposited in real time, thus calculating the concentration of black carbon with 2 different wavelengths, from almost UV (375 nm) for organic and elemental carbon to IR (880 nm) for elemental carbon.
GT-321 is a handheld particle meter that counts particles up to 0.3 microns. It is completely autonomous, with an internal battery and sampling pump. It can be programmed and there are five possible sizes for the particle in question: 0.3, 0.5, 1.0, 2.0 or 5.0 microns.
GT-521S allows users to select the size of the particles, with two programmable counting channels, each one from 0.3 to 10 microns. It shows differential or cumulative particle counts in real time. Its remote operation through RS-232 or RS-485 ports ensures an extensive control, including all the operations on a central display. Optionally, temperature and relative humidity measurement can be available.
GT-526S allows users to select among 6 sizes of particles, with six programmable counting channels, each one from 0.3 to 10 microns. It can store up to 8 000 registers. These registers can be seen, printed with an optional printer and downloaded through COMET or ASCII commands. Two limits for programmable counting warnings.
