Description
Overview
GAOTek water ammonia nitrogen sensor is a conventional water quality monitoring digital ammonia nitrogen sensor. It is made of industrial online electrode and PVC membrane ammonium ion selective electrode. It can selectively test the ammonium ion content in water with fast response and accurate measurement. Built in temperature sensor, which can automatically compensate temperature, is suitable for online long-term monitoring environment.
