Product Summary

With sensitivity drift under 3 percent per year, the tightest in the Sniffer4D lineup, the NH3 Sensing Module keeps ammonia readings accurate longer between calibrations from a single Nano 2 Plus Base Unit slot. It detects down to 1 ppm across a 100 ppm linear range, rated for 24 months of service across -40°C to 50°C and up to 95 percent RH, covering colder and more humid conditions than most modules in the lineup. Since ammonia is a leading source of reported odor complaints, it gives odor investigation and HAZMAT teams a dedicated way to trace them back to a source.

Key Features
  • Electrochemical sensor measures ammonia concentration with high precision accuracy
  • One part per million limit catches low level ammonia events
  • Wide linear range covers trace levels through high concentration events
  • Sub fifty second response delivers readings during active flight operations
  • Fine resolution captures subtle shifts in ammonia gas concentration accurately
  • Twenty four month service life supports extended field deployment cycles
  • Industry leading drift keeps calibration accurate for years at a time
  • Wide temperature tolerance operates from negative forty to fifty degrees
  • Wide humidity range functions reliably up to ninety five percent

Description

Sniffer4D NH3 Sensing Module: Detect Ammonia for Odor Investigation and HAZMAT Response

The Sniffer4D NH3 Sensing Module holds the tightest sensitivity drift and widest environmental range in the Sniffer4D lineup, giving odor detection and HAZMAT teams an ammonia reading that stays accurate longer between calibrations. It installs into a single slot on the Sniffer4D Nano 2 Plus Base Unit.

Ammonia is one of the most common sources of reported odor complaints, and this module gives Base Unit operators a dedicated way to trace those complaints back to a source, installing alongside whatever other gases a mission requires. Its wide operating range also supports colder and more humid deployment conditions than most modules in the lineup.

Key Features and Benefits

  • Electrochemical sensing: measures ammonia concentration with high precision and accuracy.
  • 1 ppm detection limit: catches low level ammonia events across sites.
  • 100 ppm linear range: covers trace levels through high concentration events.
  • Under 50 second response: delivers readings across 0 to 50ppm range.
  • 0.1 ppm resolution: captures fine shifts in ammonia gas concentration.
  • 24 month service life: supports extended field deployment before replacement.
  • Industry leading drift: sensitivity drift under 3 percent per year.
  • Wide temperature range: operates reliably from -40 to 50 degrees Celsius.
  • Wide humidity range: functions up to 95 percent RH conditions.
  • Single slot install: adds NH3 sensing without claiming the full array.

The NH3 Sensing Module exists to give odor investigation and HAZMAT programs a dependable, long-lasting ammonia reading without frequent recalibration. Its wide temperature and humidity tolerance means it holds up across colder and more humid conditions than most other modules in the lineup.

DSLRPros configures every NH3 Sensing Module for accurate, long-lasting ammonia detection before it ships. Order the NH3 Sensing Module from DSLRPros and add odor and HAZMAT-ready ammonia detection to your next flight.

Specifications
  • Detection principle: electrochemistry
  • Linear range: 0 to 100 ppm
  • Limit of detection: 1 ppm
  • Repeatability: <2% FS
  • Accuracy: ±5% FS — note: this is the first module in the batch with a separately listed accuracy spec (previous modules listed repeatability only, not a distinct accuracy figure); preserving as its own line rather than conflating with repeatability
  • Overall response time (t90): <50 seconds (0-50 ppm)
  • Display resolution: 0.1 ppm
  • On-chip proprietary individual difference compensation algorithms
  • Sensitivity drift: <3%/year (laboratory environment) — notably tighter than every other module drafted so far
  • Zero drift: <±2 ppm/year (laboratory environment) — note: expressed in ppm rather than ppb like other modules; preserving the source's unit exactly rather than converting
  • Estimated service life: >24 months
  • Operating temperature: -40 to 50°C — note: wider cold-end range than any module so far (others start at -30°C); may require zero-point readjustment due to changes in operating temperature or working environment
  • Operating humidity: 15 to 95% RH

Frequently Asked Questions

More questions? Speak with an Expert.

What makes this module's drift specifications different from other Sniffer4D modules?

The NH3 module has a sensitivity drift under 3 percent per year, which is notably tighter than every other electrochemical gas module in the Sniffer4D lineup, some of which drift 10 to 40 percent per year. This means the module holds its calibration accuracy longer between service intervals. It's a genuine standout in the lineup rather than a typical spec.

What is this module typically used for?

This module is specifically noted for odor detection and HAZMAT response. Ammonia is a common source of reported odor complaints, so this module is frequently used to trace those complaints back to a source, in addition to broader HAZMAT screening work. DSLRPros can help confirm this module fits your particular investigation or response program.

Does this module still need periodic recalibration despite its tight drift specs?

The published specifications list a zero drift of less than plus or minus 2 ppm per year in addition to the tight sensitivity drift figure, both under laboratory conditions, and the module may still require zero-point readjustment after significant changes in operating temperature or environment. We don't have a specific recalibration interval from AIRINS beyond these figures, so for long-running deployments, reach out to DSLRPros or AIRINS directly to establish a maintenance schedule.
