What is the Sensidyne AP-20S used for?
It's a stroke-counting gas detection pump used with colorimetric detector tubes for rapid direct-reading spot measurement of airborne chemicals — confined space pre-entry surveys, leak investigation, industrial hygiene spot checks, and emergency response screening.
How do colorimetric detector tubes work with the AP-20S?
Each tube contains a reagent that reacts with a specific target gas to produce a color change. You break both tube tips, insert it into the pump, and pull the required strokes to draw a measured air volume through the reagent. The color-change length or intensity is read against the scale printed on the tube to determine concentration.
What gases can be measured with the AP-20S system?
Sensidyne offers tubes covering hundreds of compounds — industrial gases, solvents, combustibles, and toxic chemicals. Each tube is specific to a target compound; confirm the correct tube and expected concentration range before sampling.
What's the most common mistake when using a colorimetric detector tube system?
Breaking the tip incompletely, incorrect tube orientation, or not completing the full required number of strokes — and using expired tubes. Always read the tube instructions before each use and check the expiration date; expired tubes produce inaccurate results.
What should I confirm before ordering the AP-20S kit?
The target gases you need to measure, the correct detector tubes for each compound and expected concentration range, and that the tube fits the AP-20S pump connection. Confirm tube availability separately — tubes are consumables ordered by gas type.
What does it cost to rent the Sensidyne AP-20S kit?
Contact RAECO Rents for current daily and weekly rates. Detector tubes are consumables ordered separately by gas type — budget tube cost alongside the pump rental based on the number of measurements and target gases for your survey.
