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 the target gas in air.

Description
Environmental Sensors Co.'s Ammonia Meter is a hand held 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 insturment has an LCD display giving concentrations in ppm, 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 (8 hour average) and Peak.
ZDL-800 Data Logging Model
The ZDL-800 Ammonia data logging meter stores all of the exposure points for up to 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, the interval between each point, and the actual exposure points. All of the log files can be easily uploaded to PC using components vailable within the Microsoft Windows Operation System or the termianl software included with the instrument.

Description
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 insturment has an 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 0-50 ppm.
With the touch of a button, the meter displays STEL (average of every 15 min.), TWA (8 hour average) 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.
