Gas Sensors Ammonia -

Ammonia can be measured in air or in liquid (dissolved) using a variety of methods. The most common method is using Electrochemical Gas Sensors, which is what all of our Ammonia products use. Ammonia is normally measured in parts per million (ppm) for human safety uses but can also be measured in percent by weight for commercial production and storage applications. All of our ammonia …

An electrochemical sensor device for measuring blood ...

Blood ammonia testing is typically performed in the central laboratory. While a number of point of care devices have been developed, these are based on classical enzymatic or colorimetric principles and have not been widely adopted. In this work, an electrochemical sensor device was developed for measuring blood ammonia. The device was based on ...

New Sensors for Ammonia Gas Detection - International Gas ...

· Existing electrochemical sensors are consumed by Ammonia as they are monitoring. This means if you have a background level in a plant room, then your sensor life will be drastically reduced. This also means, your sensor could become fully consumed and useless should a gas leak occur. In either case this leads to a detector which no longer correctly reads Ammonia, a potentially …
