Environmental Sensors Co.’s Ammonia Meter is a portable desktop instrument that measures ammonia concentration in a range of 0-100 ppm and a resolution of 0.1 ppm

The instrument makes it possible to monitor ammonia 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 0-100 ppm.

With the touch of a button, the meter displays STEL (average of every 15 min.), TWA (average of every hour) and Peak.

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-800XP 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.

Theory of operation

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 ammonia in air.


Some representative examples of the common interfering compounds and the corresponding signals they give are shown below. For example, the output of the Z-800XP when exposed to 300ppm of carbon monoxide is 0ppm. Care needs to be exercised about using this instrument in the presence of large concentrations of these gases.
