Pig Farm Odor Gas Measurement — GasTiger 2000 NH₃/H₂S/VOC Configuration (Anseong, Gyeonggi-do)

GasTiger 2000 — Pig Farm Odor Gas Measurement (NH₃ / H₂S / VOC)

This article covers odor gas monitoring inside a pig farming facility, using the GasTiger 2000 configured for NH₃, H₂S, and VOC measurement.

Why Identifying Gas Type and Concentration Matters

For accurate odor characterization in livestock facilities, it is essential to identify which gases are present and at what concentrations (ppm). Without this information, effective odor management and regulatory compliance cannot be achieved.

Supplied Configuration

• Model: GasTiger 2000
• NH₃ (ammonia) sensor: 0–50 ppm
• H₂S (hydrogen sulfide) sensor: 0–50 ppm
• VOC sensor: 0–10 ppm

Tedlar Bags and Automatic Sampling Pump

In addition to real-time spot measurement, Tedlar bags in multiple sizes and an automatic sampling pump were supplied to enable regulatory-standard grab sampling.

The pump stops automatically once the set collection volume (1 / 2 / 5 / 10 L) is reached — ensuring consistent, repeatable sample quantities without manual monitoring.

On-Site Measurement Inside the Pig Barn

Measurement was conducted inside the pig barn. A neighboring cattle barn added a distinctive rural atmosphere on arrival.

Safety protocols were strictly followed: protective coveralls were worn and disinfection procedures were completed before entering the facility.

The GasTiger 2000 delivered stable, responsive measurements throughout — providing reliable data that satisfied all parties involved.

For odor monitoring equipment in pig farms, cattle barns, or poultry houses, please consult a specialist to ensure the correct sensor configuration for your specific livestock type and site conditions.

Frequently Asked Questions

Q1. What odor gases are most commonly generated in pig farms?

The decomposition of pig manure produces NH₃ (ammonia), H₂S (hydrogen sulfide), and various VOCs (volatile organic compounds). Ammonia causes sharp respiratory irritation; H₂S is toxic even at low concentrations; VOCs are both a primary odor source and a regulatory target. All three must be monitored for effective odor management.

Q2. What are Tedlar bags used for in gas sampling?

Tedlar bags are specialized impermeable sampling containers used to capture and preserve gas samples for laboratory analysis when immediate on-site measurement is not possible. They are also specified in official odor testing standards and regulatory compliance procedures in Korea.

Q3. What is the advantage of an automatic sampling pump?

The pump automatically stops once the preset collection volume (1, 2, 5, or 10 L) is reached, ensuring a precise and consistent sample size every time. This improves repeatability compared to manual collection and allows the operator to focus on other tasks during sampling.

Q4. Is protective coverall required when entering pig farms for measurement?

Yes, without exception. Pig facilities harbor livestock viruses, bacteria, and airborne particulates. Biosecurity protocols — including coveralls and disinfection — are required both to protect the measurement personnel and to prevent the introduction of pathogens from outside the facility.

Q5. What should be considered when selecting an odor detector for livestock facilities?

The dominant odor gases vary by animal type. Poultry facilities tend to generate very high ammonia concentrations, while pig facilities often show more pronounced hydrogen sulfide. The sensor type, measurement range, and cross-interference characteristics must be matched to the specific gases present. Specialist consultation is essential before finalizing equipment selection.
