Myron L Ultrapen PT6 Nitrate Concentration & Temperature Pen sample bottles lower-cost version of the 101The Myron L Ultrapen PT6 puts nitrate screening in a shirt pocket. An ion selective sensor reports nitrate concentration with temperature, giving a direct field number in seconds instead of a colorimetric kit and a bench. Calibration uses Myron L nitrate standards (N1, N10, N100 and N1000) so you can bracket the range you actually work in. Application Used for agricultural runoff and irrigation water screening, hydroponic and nutrient solution
