nitrite ion no2 sensor probe

Nitrate Sensors/Electrodes/Probes Supplier - ZATA

Nitrate is a polyatomic ion with the molecular formula NO−3 and a molecular mass of u. Organic compounds that contain the nitrate ester as a functional group (RONO2) are also called nitrates. What does a nitrate test measure? A nitrate meter is used to measure the concentration of nitrate in water.

New Ion Sensor Probes "PRO" for Smart Water - Libelium

2016-06-14· Nitrite [NO 2-] (2,5 – 1000 mg/L) Perchlorate [ClO 4] (1 – 10000 mg/L) Potassium [K +] (0,4 – 3900 mg/L) Sodium [Na +] (0,1 – 3200 mg/L) These new sensor probes are named as “PRO” as they offer a better calibration cycle (they keep calibrated more days than the current probes). The underlying technology is not based on liquid chemicals but in solid membranes made of nanotubes of ...

Ammonia, Nitrite and Nitrate Probes? - Sensors - Arduino Forum

2021-05-06· system February 24, 2013, 4:41am #1. Hello, I am looking for probes for determining the amount of ammonia, nitrite, and nitrate present in a liquid. Specifically, I'm looking for something I can use to monitor (not adjust, just monitor) the chemical status of my fish tank. Googleing hasn't found me anything but the MQ-137 which is a gas sensor ...

An Acid-Inert Fluorescent Probe for the Detection of Nitrite

2017-03-25· The fluorescent detection of nitrite ions has been challenging owing to the poor acid-stability of typical fluorescent probes. Herein, an acid-inert rhodamine-based fluorescent probe has been developed for the fast detection of trace amount of nitrite ions with turn-on mode. The detection limit of nitrite ions was determined to be nM (S/N = 3) and the linear range with high linear ...
