NH3 Responder Ultra

Handheld Ammonia gas detectors used for detecting all levels of ammonia for leaks and hazmat response.

Lead Time: 1 day aro

  • Detection range from 0-100% LEL of Ammonia (PID: 0-1,000 PPM NH3) (LEL: 4,500 to 150,000 PPM NH3))
  • Includes Oxygen sensor with range of 0-25% O2 (vol).
  • Smaller and lighter than competitive instruments.
  • Water-resistant design in an integral concussion-proof enclosure.
  • Large LCD allows for easy-to-read monitoring.
  • Integral motorized pump for remote sampling and fast response.
  • Rechargeable lithium polymer battery (14 hours runtime @ -4F)
  • 95 dB alarm tone, bright LED alarm bars, & internal vibrating alarm for noisy areas.
  • Auto backlight: activates in low light & when in alarm.
  • Four alarm levels: instantaneous Low Alarm, High Alarm, TWA and STEL.
  • Records TWA, STEL, and max exposures to gas & displays readings on command.
  • Datalogger with programmable sampling intervals.
  • Available options for additional H2S and CO sensors (call for price and availability).
  • Part#: NH3-RESPONDER-ULTRA includes: carrying case, rechargeable battery and charger, sampling wand and hose (3ft), and stainless steel alligator belt clip.
