ET can supply a wide range of monitoring equipment for the measurement of NO, NO2 and NOx. In our latest brochure you will find the some of our professional standard options.
We drove our Smogmobile to the Gloucester Nissan garage on Friday afternoon for some routine maintenance, and saw some interesting results along the way. Predictably the NO2 levels were notably higher than in Stroud, peaking with a 1-minute average of 137 ppb (262 µg/m3) on Barnwood road. We also noticed an unusual methane spike on Eastern avenue, peaking at 3.5 ppm, 75% higher than the background concentration. It’s unclear whether this methane was coming from nearby businesses, vehicle exhausts, or something else entirely, but it was certainly an intriguing observation!
In 2015 ET announced the availability of the latest technology in ambient and trace level NO2 measurement with the T500U CAPS (Cavity Attenuated Phase Shift) direct reading NO2 Analyser, capable of “true” NO2 measurements across the ranges 0-5ppb through to 1 ppm.
We are now very pleased to report that the T500 has acquired MCERTS certification.
Now, along with our standard NOx monitor the T200 and the Ulra-sensitive T200UP (with photolytic converter) ET can offer an alternative to Chemiluminescence for those requiring MCERTS certification.
Representing the next generation of criteria pollutant monitoring technology for the direct measurement of Nitrogen Dioxide in air, the T500U CAPS measurement approach vastly reduces the amount of maintenance required whilst directly measuring NO2. Other benefits include, fast response, exceptional measurement sensitivity and low power consumption (80 Watts).
The T500 joins the Opsis System 300 open-path system (also sold by Enviro Technology) as one of only two non-chemiluminescent NO2 analyser techniques to receive UK ambient MCERTS certification.
In March 2016, Bureau Veritas - in its role as Central Management and Co-ordination Unit of the UK Automatic Urban and Rural Network - on behalf of DEFRA, purchased a number of BAM1020 PM analysers from Enviro Technology Services for both PM10 & PM2.5 to replace existing TEOM analysers on the AURN under the ET trade-in offer, providing good value for money.
Sales Director, Mike Webley said, ET has been offering equipment trade-in for a number of years to Local Authorities, & we were pleased to offer a similar contract to the national network.
Cooper Environmental’s Xact® 625i is designed for high time resolution multi-metals monitoring of ambient air, with detection limits that rival those of laboratory analysis.
Totally re-designed from the bottom up, the Xact 625i is smaller, lighter and more powerful than the Xact 625. It features improved detection limits, can measure more elements and unbelievably comes in at a significantly lower price than it’s predecessor.
It comes standard with a solid-state meteorological sensor and Cooper Environmental’s proprietary ADAPT analysis package, making the instrument one of the most powerful air pollution source detection offerings in the industry.
The system can simultaneously identify and measure multiple metals in ambient air to provide data for use in the following applications:
• Fence-line monitoring
• Source Apportionment
• Determination of background concentrations
• Spatial recognition of pollution sources
• Temporal recognition of pollution sources
• Resolve acute, short duration events
• Risk and emergency management

Micro Pulse Lidar (MPL) is a sophisticated laser remote sensing system that provides continuous, unattended monitoring of the profiles and optical properties of clouds and aerosols in the atmosphere.
Based on the same principle as radar, MPL transmits laser pulses that scatter (reflect) off particles in the atmosphere. MPL then measures the intensity of backscattered light using photon-counting detectors, and transforms the signal into atmospheric information in real time.

LGR’s new Microportable Gas Analyser (µGA) reports measurements of methane, carbon dioxide and water vapor simultaneously in a package that is compact, crushproof and travels anywhere.
As with all LGR instruments, the µGA is simple to use which makes it ideal for natural gas leak detection and other field studies, compliance monitoring, air quality studies and soil flux studies, and wherever measurements of methane, carbon dioxide and water vapor are needed quickly and sensitively.
In addition, the µGA reports and stores all measured absorption spectra which allows the instrument to accurately correct for water vapor dilution and absorption line broadening effects and thus to report CH4 and CO2 on a dry mole fraction basis without drying or post processing.
LGR’s “Extended Range” option provides accurate methane measurements at levels up to 1% mole fraction (without dilution) without reducing precision and sensitivity at typical ambient levels - a unique capability to LGR.
Features and Benefits
- 5.8 kg (w/ battery), 35 watts
- Continuous measurements
- CH4 reported at 10 Hz with ppb sensitivity
- Ideal for natural gas leak detection while walking; also, for chamber flux and soil studies, emissions monitoring
- Wide range: ppb to %
- Extended Range option allows CH4 measurements up to 1%
- Species specific - no cross interferences
- Operates directly on DC power
- Extremely fast time response
