Easy to Use Internal Pump Rechargeable Battery Short and Long Term Averaging Internal Memory (Data Logging)

The Z-100XP Ethylene Oxide Monitor is a portable desktop instrument which measures ethylene oxide concentration in air with a resolution of 0.1 ppm and a range 0-20 ppm. The LCD display updates 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. When combined with the extendable probe (an optional accessory) the internal pump makes 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 equivolent of 5 seperate 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 sensors response is linear with the concentration of ethylene oxide in air.

Interfering substances are given below as a percent of ppm ETO. For example, 1.0 ppm dimethyl ketone will show as 0.014 ppm ETO. Care needs to be exercised if using this instrument in the presence of large concentrations of these gases.
