Stack Emission Services

Our services include the isokinetic measurement of particulate matter, velocity, temperature and pressure profiles. Levego Environmental Services’ services extend further to particulate matter and fume extraction plant balancing, gas cleaning plant efficiencies, dynamic particulate matter emission monitoring, calibration of automated measuring systems, and gas producer performance.

Levego Environmental Services is uniquely positioned to offer its clients a comprehensive independent calibration service for all makes of online continuous emission monitors.

Stack Emission Services performed by Levego Environmental Services can be carried out as accredited or non-accredited results depending on the customers’ requirements. Accredited results are performed under ISO/IEC 17025:2005 SANAS accreditation number T0846.

Laboratory Services

Determination of particulate matter and sulphate analyses take place in our in-house ISO 17025:2005 accredited testing laboratory, please refer to schedule of accreditation:

Levego Environmental Services offers a comprehensive array of environmental analysis, including the supply of specialised sampling media that is outsourced to a carefully selected group of national and international accredited laboratories.

Equipment Supply

Levego Environmental Services can provide a range of portable analysers as outlined below, but not limited to.

  • Portable combustion and emission analysers,
  • Portable flame ionisation analysers (FID),
  • Isokinetic and gaseous stationary source emissions measurement equipment and
  • Toxic gas analysers
  • Portable ambient BTEX analysers

Ambient Air Quality

We offer ISO/IEC 17025:2005 accredited dust fall-out monitoring in accordance with ASTM D1739.

We co-ordinate the installation of appropriate fall-out stands, site maintenance and collection of samples at the prescribed pre-determined intervals. Samples are collated and analysed in accordance with ASTM D1739.

Levego Environmental Services’ ambient air quality assessments are performed using Radiello™ tubes for the following contaminants:

  • BTEX/VOC, aldehydes, ammonia, hydrogen fluoride, nitrogen dioxide, sulphur dioxide, ozone, phenolic compounds, hydrogen chloride, etc.

We offer an odour control solution. The service includes odour assessments, odour surveys, sampling, analysis, and odour modelling.

NAEIS Reporting

Levego Environmental Services helps with the completion of your submission requirements to the South African National Atmospheric Emissions Inventory System (NAEIS). The NAEIS is an online national reporting platform aimed at holding both air pollutants and greenhouse emissions inventories for the Republic of South Africa.

Leak Detection & Repair

Leaking equipment, such as valves, pumps, and connectors, are a large source of emissions of volatile organic compounds (VOCs) and volatile hazardous air pollutants (VHAPs).

We offer a leak detection measurements service following the requirements of US EPA Method 21 and international best practice.

PYXISGC BTEX Monitoring,

Isokinetic sampling – PM2.5/PM10 Monitoring

Mobile emissions trailer


The PyxisGC BTEX is the product of 15 years research by the Institute for Microelectronics and Microsystems (IMM) of the National Research Council of Italy (CNR) of Bologna.
PyxisGC BTEX is the ultimate solution to remotely monitor BTEX (benzene, toluene, ethylbenzene, and xylene) in air at exceptionally low concentration levels.

Free Demonstration

The PyxisGC BTEX is the first “carrier gas free” gas chromatograph for remote BTEX monitoring in ambient air. PyxisGC BTEX is manufactured in compliance with EN14662-3:2015 specifications.

The analytical module of the PyxisGC BTEX is characterised by miniaturised dimensions and high sensitivity, thanks to the combination of two technologies; Micro Electro-Mechanical Systems (MEMS) is applied to the selective pre-concentrator and to the column of chromatographic separation (proprietary technology).

Watch our video and answer the following question: Does the PYXISGC BTEX instrument require carrier gas to operate in order to measure sub-ppb concentration levels? Please send your answer to deon@levego.co.za to qualify for a free on-site demonstration.

Please use this link to access a live demo of the instrument, https://www.pollutionguardian.com/, using deon@levego.co.za as log in and password Deonpos01. The link will be live from 09H00 on Tuesday 17 November 2020.
