Benefits Of A Sulfur Dioxide Sensor

-

If you’re considering purchasing a Sulfur Dioxide Sensor, you’ll want to ensure that it has the following features: Detects up to 14 common and exotic gases, can detect SO2 levels ranging from 0.1 ppm to 4.7 ppm, and has U.V. fluorescence technology. Aside from these features, the so2 sensor you select should also be compact and easy to use.

Detects up to 14 common and exotic gases

The Honeywell BW(tm) Solo is a single-gas sensor for hazardous-area workers that delivers real-time visibility and connectivity. This sensor is compact and easy to maintain, delivering fast sensor response and a long sensor life. It is a smart choice for safety-critical applications and comes with a three-year warranty.

This sensor measures sulfur-bearing gases. The technology uses potentiometric measurements across a potassium sulfate pellet to measure concentrations of sulfur dioxide, hydrogen sulfide, carbonyl sulfide, and methyl mercaptan. The sensitivity range is up to ten thousand parts per million. The detector’s sensitivity range is very wide, meaning that other gases will not interfere with the measurement.

Can detect 0.1 ppm to 4.7 ppm

A sulfur dioxide (SO2) gas detector can monitor the air quality in your home or workplace from 0.1 ppm to 4.7 ppm. This device works by detecting sulfur dioxide in the air and can provide an alarm when the level is above or below the pre-set level. To ensure that the device works correctly, it should be tested frequently with a known source of the gas. This process is known as bump testing and is an excellent way to ensure the correct operation of your detector.

Sulfur dioxide is a colorless gas with a pungent odor. It is used in many industries and workplaces as a bleaching agent, catalyst, disinfectant, and antioxidant. It is also a commonly used preservative for food. Sulfur dioxide has an odor threshold that varies from 0.1 to 4.7 ppm. There is no standard SO2 concentration threshold, and different odor sensors may not work at different concentrations.

Is portable

A portable sulfur dioxide sensor is a useful piece of equipment for anyone who’s concerned about air pollution, especially during volcanic activity. These devices measure levels of sulfur dioxide in the atmosphere and can be easily stored when not in use. These sensors can be found for under $400, and they can provide real-time data about air quality, as well as monitor volcanic activity.

When purchasing a portable SO2 sensor, make sure it’s built to last. If possible, try to find one that is maintenance free, which means no battery change or calibration required. Also, make sure that the sensor is kept in an environment free of electromagnetic sources and harsh chemicals.

Has U.V. fluorescence

An SO2 sensor using UV fluorescence is based on the emission of characteristic fluorescence when SO2 molecules are exposed to ultraviolet light. The sensor consists of an air sample exposed to a beam of UV radiation that varies from 190 to 230 nm. This light excites the SO2 gas in the air sample and then passes it through a filter to record its intensity.

A sensor using this technology is effective in measuring low sulphur concentrations, such as those found in motor fuel. Its advantages are its sensitivity, speed, low cost per analysis, and ease of use. However, its detection limit is limited by interference caused by nitric oxide. High concentrations of nitric oxide bias the measurement of sulphur, causing a falsely positive result. This interference can be eliminated by tuning the detector’s wavelength and excitation levels.

Can be calibrated

A sulfur dioxide sensor calibration kit allows you to calibrate the sensor to a specific range. This kit is NIST traceable and includes a 58 liter gas cylinder. In addition, you will need a specific monitor adapter. You can calibrate the sensor to a range of 0-20 ppm with the kit.

The calibration gas cylinder contains a specified concentration of sulfur dioxide and nitrogen. This cylinder is labeled and includes an analysis certificate. The gas mixture is then mixed gravimetrically according to the ISO6142 standard. This ensures accuracy. The mixture also ensures optimal shelf life and stability. These gas cylinders are available with many accessories.

Typically, the calibration gas comes in a disposable steel or aluminum cylinder. It has a shelf life of six to 24 months. It also comes with a Safety Data Sheet (SDS). You can purchase a NIST traceable calibration certificate for $50.
