Air Monitors & Detectors - Single and Multigas

Air quality instruments ensure workers are not overexposed to dangerous chemicals, or oxygen- deficient or explosive environments. Environmental Equipment & Supply (EE&S) knows that a crucial part of any safety program is having reliable, high quality air monitoring instruments readily available. To help meet the safety needs of all of our clients, EE&S rents Flame Ionization Detectors (FIDs), Photo Ionization Detectors (PIDs) and Combustible Gas/Confined Space Meters (CGMs). Whether you are required to test air quality in a confined space, an industrial site, or landfill, EE&S rents the right instrument for any situation.

EE&S offers air quality monitoring instrumentation from a variety of manufacturers. We feature RKI Instruments, RAE Systems products, and Thermo Fisher in our rental fleet. All of our instruments are calibrated to manufacturers’ specifications.

Types of Instruments

Flame Ionization Detector (FID) – The FID is capable of measuring a variety of organic vapors over a wide dynamic range (0-50,000 ppm), detecting some compounds that a Photo Ionization Detector (PID) will not detect. The operation of the FID is based on the detection of ions formed during the combustion of the organic compounds in a hydrogen flame.

Photo Ionization Detector (PID) – A PID measures volatile organic compounds and other gases. They can measure in concentrations from the ppb range to 10,000 ppm. The PID uses an ultraviolet light source (bulb)to break down the chemicals that can be easily counted with a detector. The PID does not determine which compound is available, only that one or more exist. The compounds that can be detected depend on the bulb that is installed. The standard bulb is a 10.6eV.

Combustible Gas Meter/Confined Space Meter (CGM) – This instrument is typically used prior to entering a confined space. The standard configuration monitors for the Lower Explosive Limit (LEL) of combustible gases, Hydrogen Sulfide (H2S), Oxygen (O2) and Carbon Monoxide (CO).

Multigas – This term is used interchangeably between the CGM and instruments that combine the CGM and PID.

Specialty Instruments – This describes our CGMs that have other sensors such as Carbon Dioxide (CO2) or Methane (CH4).

Accessories and Calibration Kits

All confined space gas detector rentals from Environmental Equipment & Supply are delivered fully calibrated, charged, and ready for immediate use in the field. For extended use or sites that require frequent field calibration, we sell CAL gas formulated to pair with our rental meters. Calibration is easy using the gas regulator that is provided with every meter.

Additionally, EE&S offers a wide variety of other air sampling supplies and instruments – Tedlar bags, tubing, detector tubes, digital manometers, and more. Talk to one of our team to find the best solution to your air sampling needs.
