This Formaldehyde Meter HFX205-25 is designed to detect formaldehyde in air. The Formaldehyde Meter HFX205-25 shows the formaldehyde-concentration on site and thereby avoids time-consuming and expensive analysis in laboratories. The Formaldehyde Meter HFX205-25 runs with the help of an electromechanical sensor and is designed to determine the current permitted limit. A measurement can be accomplished in less than 30 seconds.
