The Thermo Scientific Model 5014i Beta Continuous Particulate Monitor uses beta attenuation technology in combination with the established iSeries platform design. The 5014i distinguishes itself from other beta measurement methods by utilising a continuous (non-step wise) mass measurement with a proven industry standard which provides for long-term unattended operation. It complies with with U.S. EPA Approved, PM-10 (EQPM1102-150) and PM-2.5 (EQPM0609-183) equivalent monitors.

The Model 5028i Continuous Particulate Monitor combines dual channel sampling technology and beta attenuation analysis on the proven iSeries platform. The unit is capable of conducting real-time measurement of two particulate matter parameters simultaneously. The 5028i offers continuous, non-stepwise measurement of particulates and complies with U.S. EPA PM-10 (EQPM1102-150) and PM-2.5 (EQPM0609-183). Two  particulate matter parameters simultaneously: PM1, PM2.5, PM10 or  TSP.

The TEOM 1405 monitor has become the de facto standard for particulate mass concentration measurements due to the high data quality, reliability and unparalleled support. Using a choice of sample inlets, the hardware can easily be configured to measure PM-10, PM-2.5, PM-1 or TSP concentrations. The TEOM 1405 monitor provides a self-referencing, NIST-traceable true mass measurement using proven high-reliability proprietary TEOM technology. It complies with U.S. EPA PM-10 Equivalent Monitor (EQPM-1090-079). 

Two particulate matter parameters simultaneously: PM2.5, PM10 or PM coarse . 

Simultaneously measure PM Fine (PM-2.5), PM Coarse, and PM-10 mass concentrations with the Thermo Scientific™ TEOM™ 1405-D Continuous Ambient Particulate Monitor. This monitor utilizes a tapered element oscillating microbalance (TEOM) for measurements with excellent short-term precision.Consisting of a TEOM mass sensor and control unit in a network ready configuration, the TEOM 1405-D distinguishes itself from other PM measurement methods by utilizing a direct mass measurement that is not subject to measurement uncertainties found in other surrogate technologies. It provides a self-referencing, NIST traceable direct mass measurement.

PM10, PM4, PM2.5 or PM1. An integrated sample filter enables post-gravimetric validation of all data. The Thermo Scientific Personal DataRAM pDR-1500 Portable Monitor is a fully integrated, real-time, high precision sampling instrument that provides maximum ease-of-use and increased operating time.

The Thermo Scientific PDM3700 Personal Dust Monitor is a real-time, respirable dust monitor for use in mining which offers accurate, continuous, personal respirable dust exposure information. The durable, belt-mounted case is made of static dissipating housing and is capable of satisfying the typical mine environment. 

The Thermo Scientific Model 15i Hydrogen Chloride (HCl) Analyzer utilizes gas filter correlation technology to continuously measure the amount of Hydrogen Chloride in the sample without the use of reagents or consumables. It is based on the principle that HCl absorbs infrared radiation at a wavelength of 3.4 microns. Because infrared absorption is a nonlinear measurement technique, it is necessary for the instrument electronics to transform the basic analyser signal into a linear output.

The Thermo Scientific™ Model 17i Ammonia Analyzer utilizes chemiluminescence technology to measure the concentration of ammonia (NH3) in ambient air. The light producing reaction of nitric oxide (NO) with ozone (O3) is the basic principle that allows reliable and stable analyser readings.

The Thermo Scientific™ Model 410i Carbon Dioxide Gas Analyzer utilises advanced NDIR optical filter technology to measure the concentration of CO2 in source emissions. Also Available with an Oxygen Sensor Module which allows the user to correct the CO2 reading for the amount of oxygen in the sample.

The Thermo Scientific Model 42i NO-NO2-NOx Analyzer utilizes chemiluminescence technology to measure the amount of nitrogen oxides in emissions and ambient air, from sub-ppb levels up to 100ppm. It is a single chamber, single photomultiplier tube design that cycles between the NO and NOx modes. The Model 42i NO-NO2-NOx Analyzer is also available with an oxygen sensor module.
