Suitable for monitoring smoke levels during wildfires, personal exposure checks, and occupational health and safety compliance.

Includes swappable sensor heads, measuring particulate matter (PM2.5, PM10), and a combined temperature and relative humidity sensor

Trigger alarms when smoke levels reach actionable limits, protecting workers and complying with all wildfire smoke regulations (including Cal/OSHA)

Kit is expandable for measurement of up to 27 other pollutants (e.g., CO, O3, NO2) - protect workers from any and all pollutants that may be putting them at risk

Product overview

The Cal/OSHA Wildfire Smoke Monitoring Kit is for employers, health and safety managers, and air quality professionals looking to monitor wildfire smoke and meet health and safety requirements under Cal/OSHA wildfire smoke regulations.

What makes Aeroqual different is the attention to data quality that we design in to all our instruments. Combined with the Series 300 monitor the PM sensor offers the following benefits:

  • Active precision active sampling

  • Fast T90 response time

  • Humidity compensation

  • K factor adjustment

Together, these features allow the PM sensor head to deliver surprisingly accurate real-time data when compared to instruments that cost 20-30 times more. In head-to-head field tests with traditional EPA-approved analyzers, the PM sensor has shown excellent correlation - with r2 correlations of 0.84 (PM2.5) and 0.81 (PM10).

FAQs

There are many different types of outdoor air pollution. Measuring them all would be too expensive, so regulators focus on a smaller group of common air pollutants, sometimes known as the criteria pollutants. The criteria pollutants are:

  • Nitrogen dioxide (NO2)

  • Sulfur dioxide (SO2)

  • Carbon monoxide (CO)

  • Ozone (O3)

  • Particulate matter (PM)

As always requirements should be confirmed with your local regulatory body.

Sensors are housed within an interchangeable ‘sensor head’ that attaches to the monitor base. You can choose from up to 28 different gas and particulate sensor heads. Each sensor head contains a single gas or particle sensor. Swapping sensor heads takes seconds and no configuration or re-calibration is required.

You can find our specifications for our sensor heads here:

Aeroqual-Portable-Fixed-Sensor-Specifications.pdf

Note: Accuracy may drift as the sensor ages.

Aeroqual recommends replacement after two years, however higher exposure levels or harsh environments can lead to a significant reduction in life expectancy. Your monitor display is likely to indicate Sensor Failure or Sensor Ageing if the sensor is nearing the end of its useful life.

Note: Sensor heads may degrade even when unused and in storage.

How many sensors can I use on the monitor at once?

You can only connect one gas or particulate sensor head at a time to monitor. However, you are able to connect the optional temperature and humidity sensor at the same time as a gas or particulate sensor head.

Can I use the PM sensor head with any portable monitor?

The PM sensor is compatible with Series 200/300/500 monitors with software version 6.4 introduced in November 2014.

What is the PPM to mg/m³ conversion factor?

PPM is an absolute measurement, whilst mg/m3 varies depending upon pressure and temperature. The portable monitor measures in PPM and applies a conversion factor if you wish to measure in mg/m3.

NH3 - 0.76, CO - 1.25, CO2 - 1.96, CL2 - 3.16, CH2O - 1.34, H2 - 0.082, CH4 - 0.72, H2S - 1.52, NO2 - 2.05, NMHC - 2.5, O3 - 2.14, C2CL4 - 6.78, SO2 - 2.86, VOC - 2.5, PM - N/A*

*as particulate matter varies in size, unlike a gas molecule, PPM is not a valid unit of measurement

Do I return the instrument for calibration?

Only the sensor head needs to be calibrated. The base unit does not need to be calibrated. All parameters are stored on the sensor head.

The sensor head calibration should be completed after the first year. Aeroqual does not recommend a second factory calibration, but rather replacement after two years of operation.

See a range of frequently asked questions on calibration here.

How long can I log data for (Series 500 only)?

The Series 500 handheld unit can store a limited number of data points (8188), meaning that the length of time that data can be logged depends upon the frequency and number of data points recorded. For example:

  • If you are logging every minute for one gas (i.e. one data point per minute) you can log for 8188 minutes.

  • If you are logging every minute for one gas, temperature and humidity (i.e. 3 data points per minute) you can log for 2729 minutes.

Decrease the logging frequency for the ability to log over a longer timeframe.

Note: Once capacity is reached new data will begin to overwrite the oldest logged data.

What communication options does the portable monitor have?

S200: None

S300: 0-5V Analog output (current reading only)

S500: 0-5V Analog output (current reading only), RS232 (current, logged data and instrument control) to PC software via USB adapter. RS232 protocol available upon request for third party software integration.

What is the “Control” function (Series 300 & 500 only)?

This is designed to control generation of a gas such as ozone from an ozone generator. The control pin can be wired to control a gas concentration between upper and lower concentration limits. The upper and lower limits can be set by the user via this control function.

Refer to the relevant section of the user guide for wiring instructions.

What accessories are available for the portable monitors?

Aeroqual offers a range of accessories to suit your application. See the range here.
