Formaldemeter htV Portable Direct Reading Formaldehyde Monitor
P/N 02700-100, Formaldemeter htV Portable Direct Reading Formaldehyde Monitor
The Formaldemeter htV portable gas detector offers a simple way to monitor levels of airborne formaldehyde in the environment. The instrument is easy to use with a simple fourbutton 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.
Easy to use – minimal training required
Rapid response time
Small, hand-held instrument
Built-in sampling pump
Standard 9V alkaline battery operation
Temperature and humidity can also be displayed
Reliable electrochemical sensor
Simple in-field calibration
Optional Base Unit for continuous monitoring
Formaldehyde is a common contaminant found in new construction, residential housing and commercial buildings following renovation. It is used in many products, industries and other types of activities, including:
In-field Formaldehyde Calibration Standard
Typically once every 3 to 5 minutes depending on previous reading.
Approx. 10 ml
0.05-10 ppm (optional high range: 80 ppm)
10% at 2 ppm level
By key interrogation, displayed in degrees C
By key interrogation, displayed in % rH
9 Volt Alkaline Battery
Instrument: 10 oz (310 g)
Complete Kit: 1.75 lb (795 g)
Instrument: 6 x 3.25 x 1.25 in (150 x 80 x 32 mm)
Carrying Case: 10.5 x 8.5 x 2 in (265 x 215 x 50 mm)
Press the ON-OFF button.
The display will show “----” followed by "0.00" (sensor ready).
Press the SAMPLE button.
The display will show "run", followed by the sound of the pump sampling the air.
The display indicates the measured concentration in approx. 10 seconds.
Switch the instrument OFF. (Instrument will automatically shut OFF after 5 minutes).
High levels, i.e., over 1 ppm, can take at least 5 minutes to "clear" from the sensor. If formaldehyde is detected, wait 3-5 minutes before turning instrument ON for next sample. To take another sample, repeat the above steps.
Retrieval of Stored Data
Instrument automatically stores the last ten readings.
With the SAMPLE button depressed, press the ON-OFF button and then release.
Instrument will display "HEAT" followed by the temperature in "C", alternating with humidity in "%rh".
With the instrument in this mode, press both CAL buttons simultaneously until the display shows "dAtA".
Release the buttons.
The display will show "run0" followed by the result of the last sample.
Scroll the last ten results using the CAL buttons.
