Nitrate (NO3−) determination can be difficult because of the high probability that interfering constituents are present in various matrices, but not with this special product. OPM NITRATE is designed and manufactured with respect to standard method of determination EPA 9210A also follows ASTM Standards D 4646 for precise detection of NO3- contents.

Built in Temperature compensation eliminates the possibilities of error and the OPM Smart controller makes the sensor even smarter.
