Ion Meter for Ammonium Ion (Outdoor Applications)


  • Out of stock




GAOTek portable Ion Meter for Ammonium Ion is designed with 2 to 5 points calibration and selectable concentration unit can be used to measure the Ammonium Ion concentration of samples. It provides the expanded memory storage and recalls up to 500 readings. It supports built-in real time clock to stamps the stored data and complies with GLP standard. It provides the calibration due reminder to calibrate the meter regularly. The GAOTek portable Ammonium Ion meter is high in accuracy and equipped with a clear and bright LCD used to display measured values, mode indicators and help message. This portable meter is more efficiently used in outdoor applications.
