Exposing Indoor Air Quality with YESDUST Particulate Sensor


Delta, B.C. – Critical Environment Technologies Canada Inc. (CETCI) recently introduced YESDUST. This particulate sensor is designed to be used in conjunction with the multi-sensor indoor air quality (IAQ) monitors developed by CETCI, such as the YESAIR.

YESDUST is a low-cost, hand-held, battery powered device. It contains a self-aspired, optical sensor that utilizes convection (heated air) to move the air through the sensing region of the sensor. The measured readings are shown on the LCD display and data logged to the internal flash card of the IAQ monitors. The device operates from its own internal rechargeable nickel hydride batteries, providing approximately five hours of run time, or a supplied wall adapter, providing continuous operation.

The YESDUST is ideal for IAQ applications containing dust, particulates, cigarette smoke, pollen, fibers, etc. Every YES product is designed to deliver years of reliable operation and is easy to operate.

For more information on the entire range of IAQ instruments and gas detection systems, please visit www.critical-environment.com.

Do you need a work place gas detector?


If you work in a strata warehouse with offices in the front and manufacturing and / or service work taking place in the rear, you may be exposing yourself to harmful gases and vapours without realizing it.

Think about it.

You spend 6 to 8 hours of your day at work and chances are you have minimal ventilation at best. Poor indoor air quality can cause symptoms such as Sick Building Syndrome and Building Related Illness.

Sick Building Syndrome is related to chemical, particulate or biological exposure that cannot be related to a specific cause but are alleviated when the occupant leaves the building. Individuals report symptoms such as headaches, nausea, fatigue and drowsiness, to eye, nose, and throat irritation.

Building-Related Illness is a specific illness with a known cause that is a result of exposure to an indoor agent. Examples are Legionnaire’s disease and Pontiac Fever.

Commercial gas detectors should be placed not only in the rear of the strata unit where the work is taking place but in the front offices for the protection of administration staff as well. Buying a low cost residential carbon monoxide (CO) detector is simply not sufficient in a work place as seen in the comparison table below.

Residential Gas Detectors

  • Low Cost
  • Easily found in local hardware stores
  • Alarm on a timed basis
  • Cannot activate ventilation equipment, phone dialer or any other alarm or notification device
  • Only calibrated before it leaves manufacturing plant.
  • Exposure limits for 8-hour time weighted average (TWA) and for 15-minute short term exposure limit (STEL) time periods

Commercial Gas Detectors

  • More expensive than residential gas detectors
  • Must be purchased through an authorized distributor/contractor
  • Alarm condition when the 15-minute average limit has been reached or surpassed
  • Can be set up to automatically activate ventilation equipment, a phone dialer or virtually any other alarm or notification device using the on-board dry contact relays
  • Workplace must meet local (provincial, state, OSHA-USA) health and safety exposure standards for toxic gas exposure
  • Professionally calibrated every month for toxic environments and 6 months to a year for non-toxic environments.
  • Provide a warning when the 8-hour average limit is reached or surpassed

Worker safety is first and foremost. Depending on what kind of work is being carried on in your place of business, some things need to be considered before purchasing a gas detector: the types of gas(es) to detect, sensor placement, and migration of gases.

You may need or desire to have gas detectors for other gases such as combustibles (flammables) which would include natural gas, propane, solvent vapours, paint vapours, etc.

Sensor placement is important for early detection and consideration must be given to the target gas. For example, natural gas is lighter than air while propane and all solvents are heavier than air. Therefore, it is recommended that natural gas sensors should be placed near the ceiling and propane sensors should be placed 6” above the floor. If sensors are to be installed in areas that could or will be considered “wash down” areas, it is imperative that a water tight enclosure be selected and a splash guard for protection of the sensor and internal electronic circuit. It is also important to ensure that the installer takes the proper steps to seal the conduit or wiring leading into the transmitter to prevent liquid incursion by using the proper conduit seals or water tight cable clamps.

The migration of toxic or combustible gases between neighboring strata units depends on the type of work they are carrying on. For example, CO is only slightly lighter than air and can migrate very easily throughout a building.

Once gas detectors are installed, they eventually need to be serviced for not only best performance but to ensure they respond well and quickly to the target gas and provide early detection of unsafe gas build up. Most local agencies responsible for health and safety regulations require that work place gas detectors be “bump” tested for safety. This means exposing the sensor(s) to a known concentration of the target gas and confirming they respond to it. If this is an enforced requirement, it may be too costly to purchase the equipment required to achieve this goal. In cases like this, your local gas detection supplier or service company may provide this service. When considering bump testing of sensors, it is important to discuss this with experts in the gas detection field. Some sensors are consumable and bump testing them with high concentrations of target gas to get them into alarm condition can shorten then life span of a costly sensor element.

Always discuss your application with your local gas detection equipment manufacturer / supplier to ensure you get the proper product for your application and to ensure you are aware of the maintenance / service costs, sensor life spans, cost of sensor element replacement, etc. then budget for these things.

YES Plus LGA


The YES Plus LGA will be replacing the Yes Plus. Photos coming soon…
The features include:

  • Accommodates 14 sensors internally including temperature and RH plus one remote sensor such as particulates, etc.
  • All fourteen internal sensors are displayed on the multi-line LCD which scrolls displaying four sensors at a time.
  • It utilizes the same plug & play sensors that the YESAIR and older YES Plus use.
  • It has a new, more powerful internal sample draw pump.
  • It data logs to an internal SD flash card like the YESAIR and use the same YES Viewer pc software program.
  • Utilizes a long life rechargeable NiMH battery pack providing from 16 to 24 hours of run time depending on sensor array installed.
  • It utilizes an enclosure from the same family as the YES Plus which allows for easy carrying and sits on a desk with the adjustable handle.
  • It will soon be available in a LGA (Landfill Gas Analyzer) package which includes internal plug-in GPS module option, internal Bluetooth wireless plug-in module option.

Gas Detectors

CETCI gas detectors are used to detect many different gases. Some of the most common are Carbon Monoxide, Carbon Dioxide, Nitrogen Dioxide, Nitric Oxide, Ammonia, Chlorine, Ozone, Combustible Gases like Methane and Propane, Oxygen, Refrigerants and more.

IAQ Monitors

The YES Series of IAQ Monitors are essential for those responsible for conducting Indoor Air Quality (IAQ) Investigations. These instruments are specifically designed to measure and record the quality of indoor air in offices, buildings, homes, schools, parking garages, ice rinks, etc.
