Nitrous Oxide Vapor Monitor

Nitrous Oxide Vapor Monitor

  • $45.00


Nitrous Oxide Vapor Monitor can be worn as a badge near the breathing zone to measure personal exposure, or placed in a room to measure area concentration.

Workplace Exposure Monitoring

Measurement of personal exposure is very easy. Clip the monitoring badge near the breathing zone of the worker. Record the start time and the stop time of the test on the pouch of the badge and return it to the laboratory for analysis in the mailer provided. The analysis report will show the average concentration of the worker’s personal exposure level.

According to OSHA regulations, each person who uses a toxic gas as a regular part of their job must have their exposure monitored periodically.

Indoor Air Monitoring

Place or hang the badge in your home for 24 hours. Record the start and stop times and send the badge back to the laboratory for analysis in the mailer provided. The analysis report explains if the concentration level of your home is exceeding the exposure limit.

Nitrous Oxide is a colorless gas at room temperature with a slight metallic scent and sweet-taste.  It is used as an anesthetic and is also known as "laughing gas".

Observe strict safety precautions and have a properly ventilated work-space.

  • used as an anesthetic

Principle of Operation

Air diffuses through a micro-porous membrane and collects vapor on special prepared adsorbents inside the monitoring badge.
