online ammonia gas sensitivity detector
The ammonia gas sensitive electrode method is an effective method to measure the ammonia nitrogen content in samples. Ammonia gas electrodes are also often used in online instruments, such as the determination of ammonia nitrogen content in water.
Ammonia gas electrode, which has the advantages of simple measurement, fast and accurate response, can be used with PH meter, ion meter and online ammonia nitrogen analyzer, widely used in biological samples ammonia nitrogen, soil ammonia nitrogen, surface water ammonia nitrogen, sewage ammonia nitrogen measurement, and online determination of ammonia nitrogen in water.
Application:
measurement of ammonia nitrogen in high purity water in power plant; ammonia nitrogen in fish pond, ammonia nitrogen in sea water; measurement of ammonia nitrogen in wastewater; NH 4 + in plating tank (black nickel plating); measurement of total nitrogen in biological samples (such as amino acid oral liquid), ammonia nitrogen in paper chemicals (cationic starch), total nitrogen in dairy products, and total nitrogen in chemical fertilizer.
