INTRODUCTION

 

Z-300XP Formaldehyde Meter

Environmental Sensors Co.’s Formaldehyde Meter is a portable desktop instrument that measures formaldehyde concentration in a range of  0-30 ppm and a resolution of 0.01 ppm.

The instrument makes it possible to monitor formaldehyde vapor in air.  The instrument has a LCD display giving concentrations in ppm every 10 seconds, a low battery indicator, and an audible alarm that can be set at any level from 0-30 ppm.

With the touch of a button, the meter displays an average concentration.

The internal pump makes it possible to sample from hard-to-reach areas or confined spaces by attaching a flexible tube to the meter.

Data Logging

The Z-300XP meter stores all of the exposure points for up to  14,400  at 10 sec. interval in 5 logs (a log is created in the instrument’s internal memory each time it is used).  A log contains: date, time, number of exposure points.  All of the log files can be easily uploaded to PC using components available within the Microsoft Windows Operating System or the terminal software included with the instrument.

type, which contains a working and an active auxiliary electrode. The signal from the auxiliary electrode is used for temperature compensation and to improve the selectivity of the entire sensor. The sensor response is linear with the concentration of formaldehyde in air.

ELIMINATES INTERFERENCES

The Z-300XP Formaldehyde meter uses a filter cartridge to eliminate many of the common interferences.

The procedure is simple. Insert the filter cartridge into the air intake receptacle la- beled “Filter” in the back of the meter.

With the use of the filter system, interfer- ences are virtually completely removed.

Only certain aldehydes and ketones need

to be considered. The filters do not permit separations of these classes of compounds.
