Indoor Air

EnviroCheck Spot tests are performed for rooms and forced hot air heating and air conditioning systems for mold, yeast and fungus. There is an incubation period and the user needs to count colonies formed.

Dosimeter tube tests for other gases.

Ozone Detector

Kit

Each Ozone Test Kit includes: Four One-Hour

Ozone Test Cards in 2 pouches. A new ozone test card is white. If ozone is present, the card will change color. The color is compared to the color

Enviro-Tester on the chart representing different levels of ozone.

Hold the test up to an air vent for 60 seconds and read the results in 24 to 72 hours by comparing growth to the provided mold density chart.

Research

Air sampling done on a pretreated Petri dish with added gel. Any spores floating in the air will stick to the moist medium surface and cover with the

Petri dish top after 1 ~ 2 hours. After 36-40

LaMotte hours, the user visually counts the number of mold colonies (noting if they are all the same or if

Water there are different types).

Swirl or dip strips according to instruction. Read color change and compare with color chart.

Vial and test strips included. Water to be tested for bacteria is collected in a vial with bacterial growth powder and after 48 hours a positive or negative response is obtained depending on the color observed. Lead and pesticides positive/negative presence is tested with a strip that provides a visual line that allows user to determine the presence or absence of analyte. Nitrate, nitrite, iron are tested with strips that undergo a color change that compared with color chart.

Bacteria yes/no confirmatory analysis.

Test strips results are compared against the color charts provided.

Analysis Test

Kit can be interpreted as a positive or negative response according to instructions. Nitrate, nitrite, chlorine are tested using a strip and comparing the color change with a chart.

For mold test, the water sample place on Petri dish. Number of colonies (dots) counted after 48 hours, rechecked after 72 hors.

Other analytes-sample place on test strip and results are a color change that is compared with a chart.

Test strip placed in vial containing water sample.

In 10 minutes a visual positive/negative response is obtained by comparing lines in the stip. Detects

Lead down to, or below, EPA action level of 15 parts per billion (ppb).

Tests are based on a colorimetric change. For bacteria the color change provides a yes/no response in a vial.

For other analytes: a test strip provides a visual change that is compared with a color chart

Requires addition of three reagents. Final result is read from a color changing strip and compared to a chart.

Requires timing each step.

Test Kit

Water to be tested for bacteria is collected in a vial with bacterial growth powder and after 48 hours a positive or negative response is indicated by a color change.

Includes 3 reagent solutions and a reagent powder. The analytes react are equimolar with reagents giving a visual change.

Bacteria tested on vial with growth powder and after 48 hours a positive or negative response is obtained depending on the color observed. Lead and pesticides positive/negative presence compared with line on strip. Nitrate, nitrite, iron- color change observed on the specific strip is compared with color chart.

Test agent is added. The film is stored. After 3-7 days look for dozen-hundreds of dot colonies and check reference material for interpretation of results.

Measures leachable lead by turning pink or red on contact with the surface.

A solution is mixed and place in an applicator bottle. After placing drops onto a paint sample a color change may be observed. It the sample turns

black, there is lead present in quantities greater than 1 percent.
