CO ANALYZER
• Cross-flow non-dispersive infrared detector; Low range: 0-5 ppm F.S.• AS type (anti-shock) interference-compensating detector and purifier for reference gas.• Reference gas purifier oxidizes CO to CO2 to eliminate interferences.• Optics remain free of foreign matter with elimination of reflecting mirrors.
NOX ANALYZER
Continuous NOX, NO, NO2 measurements using a dual cross-flow single chemiluminescence detector and referential calculation.HORIBA original detector (Silicon photodiode sensor) respond to gas concentration quickly .Stable, repeatable measurements; Low range: 0-0.1 ppm F.S.Includes auto-recycle internal drier to make dry air for generating ozone gasBase configuration includes: O3 drier unit, O3 decomposer, reference gas generator and sample pump.
SO2 ANALYZER
• UV-fluorescent detector resistant to moisture
interference; Low range: 0-0.05 ppm F.S.
• Alternately to FDP measurements, the detector design is highly SO2 selective and requires no supplemental gas.
• Integral HC-cutter with a selective membrane eliminates interfering components
.• Incorporates a lamp intensity compensator
• Uses a built-in inert PTFE sample inlet filter.

US EPA TE-WILBUR Low Volume PM2.5 and PM10 FRM Sampler
The TE-Wilbur is a Federal Reference Method (FRM) low volume air sampler designed for EPA-compliant ambient particulate monitoring. Designated as FRM RFPS-0714-216 for PM10, RFPS-1014-219 for PM2.5, and RFPS-1014-220 for PMc, this sampler operates at variable flow rates from 1 to 25 SLPM and supports multiple particulate fraction collection including TSP, PM10, PM2.5, PM1, and custom size-selective configurations.
US EPA Federal Refernce MethodTotal Suspended Particulate (TSP)
The Polyurethane Foam Sampler is classified as a high volume air sampler for the collection of airborne volatile organic compounds and particulate matter. This sampler operates between 125-250 lpm and uses either a manual motor speed controller or the PLUS controller to control the flow rate.
US EPA Federal Reference MethodPM10
The PM10 high volume air sampler collects particulates at a flow rate between 36-60 ft³/min through a PM10 size-selective inlet. As the particulates travel through the size-selective inlet, the larger particulates are trapped inside of the inlet as the smaller PM10 particulates continue to travel through the PM10 inlet and are collected on the 8″ x 10″ quartz filter paper. This quartz filter is weighed previously to sampling and then after sampling to determine the mass of particulates that are smaller than 10 microns.
