Formaldemeter htV Portable Direct Reading Formaldehyde Monitor
Easy to use - minimal training required
Rapid response time
Real time readings allow immediate response to results
Reliable electrochemical sensor
Does not require inconvenient ancillary sampling equipment or readers
Simple in-field calibration
Small, hand-held instrument
Light-weight
Optional Base Unit for continuous monitoring
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.
Also available, the Glutaraldmeter 3, for glutaraldehyde monitoring.

Accessories and Replacment Parts
Phenol Filters (supplied with instrument kit) These filters can be used, when necesssary, for the removal of phenol and resorcinol.
Calibration Standard (supplied with instrument kit) The calibration standard is a tube which produces a known concentration of formaldehyde vapor for testing and, if necessary, adjusting the accuracy of the monitor. The standard has a 100-sample capacity or a useful life of six months, whichever occurs sooner.
Options
AMS-2 Base Unit
The Base Unit automates operation of the Formaldemeter htV for semi-continuous sampling. Monitoring of all three parameters (formaldehyde, temperature, and humidity) is possible with the AMS-2, giving real-time data and alarm (TWA/STEL) levels. A built-in printer provides a record of the results. All data is stored and can be downloaded to a PC via RS-232 and available download software.
AMS-2/htV Download Software
Data logged into the AMS-2 can be viewed on the LCD and outputted to the integral printer. If required, the data can be downloaded to most PC based spreadsheets using the AMS-2/htV Download Software.
