GasTiger 2000/3000 NH₃/H₂S Detectors — Pig Barn Odor Reduction Compost System Developer (Gyeonggi-do)

Pig Barn Odor Reduction Compost System Developer — NH₃ and H₂S Detector Delivery

This delivery supplied GasTiger 2000 and GasTiger 3000 portable multi-gas detectors to a company in Gyeonggi-do specializing in the development of odor reduction systems for pig farming facilities. The recipient develops enclosed high-speed fermentation (compost) systems that process livestock manure and minimize odor emissions. Accurate measurement of NH₃ (ammonia) and H₂S (hydrogen sulfide) concentrations is essential for verifying the odor reduction performance of these systems during development and customer demonstration.

What Is a High-Speed Enclosed Compost System?

A compost system processes livestock manure, food waste, and agricultural byproducts through controlled organic fermentation to produce organic fertilizer. Enclosed high-speed fermentation units conduct this process within a sealed chamber, minimizing odor release to the external environment and accelerating the decomposition timeline. Precision measurement of NH₃ and H₂S is critical for verifying fermentation efficiency and odor reduction performance at each stage of the process.

Delivery Configuration

Characteristics of Primary Odor Gases in Pig Farming Facilities

• NH₃ (Ammonia) — TWA 25 ppm, STEL 35 ppm. Major odor component of livestock manure decomposition. Strong pungent odor detectable by humans at 1–5 ppm — primary driver of community complaints
• H₂S (Hydrogen Sulfide) — TWA 1 ppm. Rotten-egg odor; generated during anaerobic decomposition of pig slurry and manure. Potent odorant at low concentrations; acutely hazardous at elevated concentrations
• VOC (Volatile Organic Compounds) — Aggregate measurement of odor-active compounds including methanethiol, indole, and skatole
• CH₄ (Methane) — Primary byproduct of anaerobic fermentation. Explosive range: 4–15% LEL

How the Detectors Are Used by Odor Reduction System Developers

• Comparative NH₃ and H₂S measurement at fermentation unit inlet and outlet — quantitative verification of odor reduction efficiency
• Stage-by-stage gas concentration monitoring throughout the fermentation cycle — data for process optimization
• Performance test and certification data recording before system delivery to customers
• Live demonstration measurements during on-site customer evaluations

Frequently Asked Questions

Why are both GasTiger 2000 and GasTiger 3000 used together?

GasTiger 2000 supports simultaneous measurement of up to four gases — including NH₃ and H₂S alongside other relevant gases — making it ideal for field multi-gas screening. GasTiger 3000 applies specialty high-sensitivity sensors capable of accurate measurement at high concentrations of a single target gas. Together, the two instruments cover both broad-range field monitoring and precision high-concentration quantification.

Will standard sensors be damaged by the very high NH₃ concentrations typical in pig farming environments?

Prolonged exposure to high NH₃ concentrations (several hundred ppm and above) does accelerate electrochemical sensor degradation. GasTiger 3000 uses high-concentration-rated sensors for improved durability. For GasTiger 2000, flushing the detector with fresh air immediately after high-concentration measurements removes residual gas from the sensor chamber and extends service life.

What are the key performance metrics for odor reduction compost system validation?

The NH₃ and H₂S concentration reduction ratio between inlet and outlet is the primary performance metric. For example, an inlet reading of 500 ppm NH₃ reduced to 10 ppm at the outlet represents a 98% reduction efficiency. Supporting data including total VOC reduction, temperature and humidity profiles, and the time-series NH₃/H₂S concentration curve across the fermentation cycle are also important for comprehensive performance documentation.

Can individual livestock farmers also adopt these detectors?

Yes. GasTiger 2000 is suitable for direct field measurement of NH₃ and H₂S in pig barns, cattle sheds, and poultry houses. Regular monitoring provides farmers with objective data for managing odor levels and responding to community complaints with verifiable evidence.

Is odor measurement legally required for livestock facilities in Korea?

Under the Odor Prevention Act, livestock facilities above a specified scale are required to comply with odor emission standards; local government odor complaint investigations can also trigger mandatory measurement and reporting obligations. GasTiger instruments are appropriate for self-monitoring purposes; statutory compliance measurements should be conducted by a certified environmental measurement agency.
