- Continuous data collection 24/365
USD 350 ea
Proving reduction outcomes for programs such as low-carbon certification and carbon credit projects requires accurate measurement data. Yet the livestock industry still relies on estimation methods that use averages and assumed values to determine methane emissions.
The MeTech Methane Monitor Capsule continuously measures concentration in the rumen where methane is produced, confirming actual output and precisely capturing how feed additives and improved husbandry conditions affect emissions.
Measured at the Source
By measuring directly in the rumen where methane is generated, it eliminates the 20-30% error found in conventional measurement methods.
Continuous Measurement
Unlike feed-station, optical-analyzer, and respiratory-mounted approaches, it collects data through 24-hour continuous measurement.
Clinical Validation
Accuracy is being refined through a one-year clinical trial at Seoul National University and field testing on commercial farms in Korea.
How It Works
Capsule Administration
Given orally to settle in the rumen. Unlike wearables, it requires no maintenance or inspection.
Methane Concentration Measurement
Measures CH₄ concentration directly inside the rumen, removing atmospheric dilution error.
Data Transmission
Transmits data via LoRa through the farm gateway over a range of up to 1km.
Emissions Analysis
Analyzes continuous data to aggregate emissions at the animal and farm level.
Report Delivery
Review results on the platform and extract data for inventory, research, and credit verification.

FAQ
Methane is a key greenhouse gas in the livestock industry, and accurate measurement is the starting point for low-carbon livestock, low-carbon feed verification, ESG, and building an MRV system.
The Methane Monitor Capsule continuously measures methane data per animal, providing foundational data across a range of fields
Most existing equipment measures from the breath a cow exhales (burps), but the Methane Monitor Capsule measures directly inside the rumen where methane is produced.
It is barely affected by external conditions, continuously collects data per animal, and enables long-term pattern analysis.
The rumen is where methane is produced, and most of it is released through burping.
Through additional research, we plan to cross-check the Methane Monitor Capsule’s continuous data against standard emissions verification methods to improve precision.
It is used in fields that require detailed data, such as low-carbon livestock certification, low-carbon feed efficacy verification, methane-reduction technology assessment, R&D, ESG reporting, and carbon credit projects.
It continuously collects measurement data more than 100 times a day. This enables more accurate analysis of methane emission patterns than conventional methods that measure only at specific moments.
In-rumen measurement data is stored on a cloud server via LoRa communication through a gateway installed on the farm. Methane data can be reviewed through the platform and the carbon toolkit.
The Methane Monitor Capsule can be used together with existing solutions such as methane-reducing feed additives, and we are developing it for use in low-carbon certification and carbon credit projects that quantitatively verify reduction outcomes.
Based on methane measurement data, we are building an MRV system that meets international standards, with the goal of developing it into a data platform usable for low-carbon certification and carbon credit projects.
It is not just a sensor but an integrated data platform spanning direct in-rumen measurement, AI analysis, and future connections to methane reduction and carbon credits.
What sets it apart is that it links health management, methane measurement, reduction, and carbon credits into a single ecosystem.
