The Formaldemeter htV offers a simple way to monitor levels of airborne formaldehyde in the environment. The instrument is easy to use with a simple four-button keypad and features an easy-to-read four-digit display. It employs a well-proven electrochemical formaldehyde sensor that will provide an immediate indication of formaldehyde levels. Unlike other formaldehyde monitoring devices, such as, color stain tubes and badges, the Formaldemeter htV is capable of measuring many samples consecutively without the need for inconvenient ancillary equipment. Real-time results also mean that potential overexposures can be identified as they occur, without the delay and expense associated with laboratory analysis.
