Portable gas analysers for biogas characterisation, flare efficiency testing and cookstove emission measurement — calibrated instruments for Verra and Gold Standard MRV.
For projects requiring gas composition analysis — biogas methane content, flare efficiency, landfill gas quality or cookstove combustion — portable gas analysers provide on-site measurement without waiting for laboratory results. Knowing your gas composition is essential for accurate flow-to-emission calculations and for troubleshooting underperforming digesters or gas recovery systems.
Gas analyser calibration is typically required every 6–12 months. Budget for calibration gas cylinders as a recurring consumable cost.
The standard instrument for landfill gas and biogas characterisation. Measures CH₄, CO₂, O₂, H₂S and balance gas simultaneously with ±0.5% accuracy. Bluetooth data logging, onboard report generation, and a 4-hour battery. Widely accepted by UK Environment Agency and used by carbon project developers to characterise gas streams before flow metering installations.
Gas composition data from a calibrated analyser is required to convert volumetric flow measurements to CO₂-equivalent emissions — without it, you're estimating methane content, which most VVBs won't accept for MRV purposes.
A personal gas alarm rather than an analytical instrument — for personal protection when working around biogas, landfill gas or any site with potential H₂S, CO or methane exposure. Clips to clothing, alarms on four gases simultaneously. Mandatory PPE on most classified gas sites. Rechargeable, with bump test required before each entry into a gas area.
H₂S is odourless at concentrations above 100ppm (which can be immediately dangerous) — you cannot rely on smell. A personal 4-gas monitor is non-negotiable PPE for anyone entering a biogas or landfill gas area. Your site safety induction will require it.
For cookstove emission factor measurement and flare efficiency testing — both common requirements in cookstove and biogas flaring carbon projects. The Testo 340 measures O₂, CO, NO, NO₂ and SO₂ in flue gas with high precision. Used by combustion engineers and increasingly by carbon project developers verifying stove emission performance against methodology baselines.
Cookstove carbon methodologies require measured emission factors for the project stoves. A calibrated flue gas analyser provides the measured data that distinguishes your project's actual performance from the default values — which directly affects credit issuance volumes.
