NIOSH's recommended exposure limit (REL) is more conservative at 25 ppm TWA plus a 35 ppm short-term exposure limit (STEL) over any 15-minute period. Many facilities set internal exposure targets to the NIOSH level rather than the OSHA PEL.\u003c\/p\u003e\n\u003cp\u003eThe SST1-A has configurable alarm setpoints for low, high, TWA, and STEL — set to match your facility's exposure program (OSHA, NIOSH, ACGIH, or a stricter internal standard).\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails open\u003e\n\u003csummary\u003eWhere is ammonia detection required or recommended?\u003c\/summary\u003e\n\u003cp\u003eAmmonia detection is a compliance or best-practice requirement in several settings: industrial refrigeration systems containing more than 10,000 pounds of ammonia (OSHA's Process Safety Management standard, 29 CFR 1910.119); refrigeration systems covered by the IIAR (International Institute of Ammonia Refrigeration) standards; agricultural operations handling anhydrous ammonia; and any workplace where ammonia is used or stored that falls under OSHA's respiratory protection standard (29 CFR 1910.134).\u003c\/p\u003e\n\u003cp\u003eCommon industries that rely on the SST1-A: cold storage and food processing (refrigeration compressor rooms), poultry and dairy farming (ambient NH3 in barns), fertilizer distribution and application (anhydrous ammonia), industrial cleaning, and chemical manufacturing.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails open\u003e\n\u003csummary\u003eWhy can't I just rely on smell to detect ammonia?\u003c\/summary\u003e\n\u003cp\u003eAmmonia has a very distinctive pungent smell at low concentrations — most people can detect NH3 easily at 5 ppm. But at higher concentrations, olfactory fatigue sets in fast: the sensory nerves become desensitized within minutes, and workers can no longer reliably tell whether concentrations are rising or falling. Olfactory fatigue is well-documented for NH3 and is a major reason continuous instrument monitoring is required in ammonia-intensive facilities.\u003c\/p\u003e\n\u003cp\u003eA continuous readout in ppm from the SST1-A shows the actual concentration regardless of nose adaptation.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails open\u003e\n\u003csummary\u003eWhat does \"serviceable\" mean on the SST1-A?\u003c\/summary\u003e\n\u003cp\u003eTraditional single-gas monitors are single-use — when the sensor reaches end-of-life (typically 2–3 years), the whole unit gets replaced. The SST1 platform is designed to be serviced: the NH3 sensor cell can be replaced, extending the monitor's service life beyond the sensor's own lifespan. PK Safety services the WatchGas SST line in-house — send the unit in when the sensor needs replacement.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails open\u003e\n\u003csummary\u003eDoes the SST1-A work with the WatchGas SST-DOCK docking station?\u003c\/summary\u003e\n\u003cp\u003eYes.
