Jumo India Pvt Ltd offers Gas-Sensitive Sensor for Measuring Ammonia. Jumo India Pvt Ltd is DIN EN ISO 9001 and DIN EN ISO 14001 certified company. Gas-sensitive Sensor for Measuring Ammonia can be used in aqueous solutions. The ammonia sensor consists of a pH glass electrode and a reference electrode. Both electrodes are in an electrolyte. The electrolyte is separated from the sample medium by means of a hydrophobic, gas-permeable membrane. The pH of the electrolyte changes if NH3 gas diffuses through the membrane. This local change in pH is measured by the pH electrode as a high-resistance value.
