What the Forensics Ammonia Detector detects (and what it doesn’t)

It detects ammonia (NH3) only — not O2, combustibles, CO or H2S. For the four atmospheric gases use a Forensics 4 Gas Meter; for other single toxics see the Chlorine or SO2 analyzers. Ammonia refrigeration plants often also monitor for the explosive range; this is a toxic-exposure monitor, not explosion-rated. Bump-test with NH3 calibration gas and recalibrate on schedule.

Frequently asked questions

What does the Forensics ammonia detector measure?

Ammonia (NH3) only. For O2, LEL, CO and H2S use a 4 gas meter; for other toxics see the specialty analyzers.

Where is an ammonia detector used?

Poultry and livestock barns, ammonia refrigeration plants, fertilizer handling, wastewater/digesters and industrial cleaning.

Is it durable for farm and plant use?

Yes — it passes a 10 ft drop test and has large digits for easy reading in the field.

Is it explosion-rated?

No — it is a toxic-exposure monitor. Ammonia is also flammable at high concentrations; for explosive-range monitoring use a rated Fixed Gas Detection Systems or Portable Gas Detectors combustible instrument.

How is it powered?

It is battery powered and compact at 224 g; keep spare batteries for long shifts.

Does it have alarms?

Yes — audible and visual alarms trigger when NH3 exceeds the set point.

How do I keep it accurate?

Bump-test with ammonia calibration gas and recalibrate on the manufacturer's schedule; replace the sensor when it reaches end of life.

Can it detect other gases?

No — it is NH3-specific. For chlorine use the Forensics Chlorine Analyzer; for SO2 the SO2 Analyzer.

Is it good for ammonia refrigeration?

Yes — it is suited to NH3 refrigeration plant exposure monitoring, alongside any required fixed detection.

Is it in stock and how does it ship?

Use the Amazon buy button for current availability and delivery timing through our fulfillment partner.

What are the OSHA limits for ammonia?

Set alarms to the applicable OSHA PEL and ACGIH TLV for ammonia; confirm current values for your program.

Do I need a personal monitor too?

For continuous per-worker exposure, pair it with a Personal & Wearable Gas Detectors clip where one is available for your gas, or wear this where appropriate.
