Ozone Test Strips

Ozone Test Strips provide a quick indication of ambient levels of ozone in both indoor and outdoor air. Because high concentrations of ozone have been medically proven to damage lung tissue and reduce lung efficiency by up to 20%, it is important to monitor ozone levels within an area.

Ozone Test Strips

  • Simple to use
  • Chemically treated to react with ozone
  • Easy to read colour reaction

Simply place in the area to be tested. After 10 minutes the test strip is compared with the colour scale on the test strip package. The strip will produce a result as a colour change in four distinct colours, from light yellow to dark yellow. Each colour represents a specified level of ozone concentration ranging from <0.045 ppm to >0.105 ppm (<45 ppb to >105 ppb), as below:

Indication Ozone Concentration
A < 0.045 ppm (45 ppb)
B 0.045 ppm to 0.075 ppm (45 to 75 ppb)
C 0.075 ppm to 0.105 ppm (75 to 105 ppb)
D > 0.105 ppm (105 ppb)

Note: For use in environments with Relative Humidity between 30 and 60%RH.

Elemental Mercury Passive Sampler

The SKC 520 Series Elemental Mercury Sampler measures worker exposure levels as a Time-Weighted Average (TWA) and permits the positive analysis of elemental mercury vapour. It is designed for analysis using standard laboratory equipment, and therefore, the cost per measurement is kept to an absolute minimum compared to other samplers. The sampler only samples elementary mercury (Hg) in the vapour phase; it does not sample elemental Hg in the particulate phase or organic mercury compounds.

Mercury vapour enters the sampler by positive, controlled diffusion so that a known sample volume is taken for a given period of time. Mercury is completely adsorbed onto the solid sorbent. The sorbent capsule is then taken to an accredited laboratory where the sorbent is dissolved in acid and analyzed by flameless atomic absorption. The sampler holder is cleaned and reused, thereby reducing sampling costs.

    • Extensive field testing and chamber studies show accuracy without interference from either moisture or chlorine
  • Simple analysis
    • Uses standard laboratory equipment and analytical methods

Note: For sampling low levels of mercury, use a sorbent tube.

UMEx 100 Passive Sampler for Formaldehyde

The UMEx 100 Passive Sampler for formaldehyde was developed in collaboration with the National Institute of Working Life in Umea, Sweden.

Constructed of tough polypropylene, the single-use UMEx 100 contains a tape treated with 2,4-dinitrophenylhydrazine (DNPH) for reliable collection of formaldehyde. Samplers are provided in individual aluminiumised pouches that can be used to transport the sampler to a laboratory after sampling.

For convenience and quality control assurance against contamination, each sampler incorporates a "blank/correction" section in addition to the active sampling section so there is no need to send extra samplers to the laboratory.

The shelf-life date is printed on a label on the outside of each pouch for easy inventory management. The UMEx 100 Sampler includes a clip for attachment to a worker’s collar for personal sampling or in an appropriate location for area sampling.
