AMT100 Series has an Ammonicap sensor with a polymer thin-film technology that operates in a temperature range of -40 to 140 oF (-40 to 60oC) and 0 percent to 100 percent relative humidity. Because it is specific and selective to ammonia, the detector reduces false alarms and other gases and odors will not affect the measurement. From Vaisala Inc., it is offered in measurement ranges of 0 to 100 ppm and 0 to 1,000 ppm. The unit's sensor is not affected by changing humidity levels, and it recovers well from high ammonia concentrations.
