Ammonia Gas Detectors: Rent or Buy
Ammonia (NH₃) is a colorless gas with a sharp, pungent odor widely used in refrigeration systems, agriculture (fertilizers), cleaning products, and chemical manufacturing. At elevated concentrations, ammonia is a severe respiratory irritant, causing coughing, burning of the nose and throat, and at high levels, pulmonary edema and chemical burns to mucous membranes.

COMPARE OPTIONS
Ammonia detectors side by side
| Instrument | Monitoring | Detection method | Range | Resolution / lowest alarm | Gases at once | Sampling | Battery run time | Intrinsically safe | Data logging | Starting at |
|---|---|---|---|---|---|---|---|---|---|---|
| Multi-Gas Monitors Read several gases at once from interchangeable sensors, worn on the body or set down as an area monitor. The sensors fitted decide which gases they read. | ||||||||||

For instruments that take interchangeable sensors or cassettes, range and resolution are for the NH₃ sensor or cassette. Run times are manufacturer estimates and vary with configuration and conditions. Not sure? Talk to our team.
WHERE EXPOSURE OCCURS
Risks: Where Ammonia Exposure Occurs
Ammonia (NH₃) exposure is a serious respiratory and eye hazard, especially during leaks from refrigeration and industrial processes. Rent ammonia monitoring instruments from RAECO Rents for cold storage and refrigeration systems, chemical manufacturing, agricultural operations, and wastewater facilities. We provide practical support selecting the right detector and sensor for the job, with fast turnaround and phone support so you can get usable field readings quickly.
Refrigeration & cold storage
Ammonia refrigeration systems in food plants and warehouses can leak at valves, compressors and piping.
Typical setup: Personal NH₃ monitors for maintenance staff plus area checks near machinery rooms.
Agriculture & livestock
Fertilizer handling and enclosed animal housing.
Typical setup: Personal ammonia monitors for workers in barns and fertilizer handling areas.
Wastewater treatment
Treatment processes and enclosed areas where ammonia can build up.
Typical setup: Multi-gas monitors with an NH₃ sensor.
Chemical manufacturing & cleaning
Production, transfer and cleaning operations that use ammonia or ammonia solutions.
Typical setup: Personal ammonia monitors during transfer and cleaning work.
EXPOSURE LIMITS
Ammonia exposure limits
- TWA50 ppm (35 mg/m³)
- TWA25 ppm (18 mg/m³)
- STEL35 ppm (27 mg/m³)
- IDLH300 ppm
- TWA25 ppm (17 mg/m³)
- STEL35 ppm (24 mg/m³)
TWA = 8-hour time-weighted average (NIOSH RELs are 10-hour). STEL = 15-minute short-term limit. IDLH = immediately dangerous to life or health. Updated October 8, 2026.
