Z-1200XP is a portable desktop instrument which features an internal pump. Ozone concentration in air can be measured with a resolution of 0.01 ppm and a range 0-2 ppm. The LCD display outputs the concentration (in ppm) every 10 seconds. The instrument also computes a 15-minute average and a Time Weighted Average (updated hourly for up to 8 hours). These values can be viewed anytime during the measurement procedure. The internal pump can be combined with an extendable probe, to make it possible to sample from hard to reach areas or confined spaces.
With the data-logging feature enabled, the meter will store all of the exposure points for each use. The maximum storage capacity is 14,400 data points. This is the equivalent of 5 separate 8-hour uses. The data is easily uploaded to PC using components available within the Microsoft Windows Operating System or the terminal software included with the instrument.
The sensing element of the instrument is an electrochemical cell. The cell is a four-electrode 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 ozone in air.

Interferences
This sensor may respond to certain gases in addition to ozone. This table shows the typical response expected, when the meter is exposed to a given gas concentration of the specified gas. Care needs to be exercised about using this instrument in the presence of large concentrations of these gases.
