HORIBA LAQUAtwin NO3-11 C

Minimum sample range: 0.3mL Measuring range: B-741; 100 to 9900 ppm / 23 to 2200 ppm B-742; 30 to 600 ppm / 6.8 to 140 ppm B-743; 62 to 6200 ppm / 14 to 1400 ppm Auto range change Temperature compensation Two point calibration IP67 waterproof Auto hold Automatic power off (30m) Operating temp: 41 to 104F (5 to 40C) The Horiba B-741 / B-742 / B-743 LAQUAtwin Nitrate Meter is the only compact meter for a quick measurement of nitrate ion using ion selective membrane. Flat sensor technology and 60 years of sensor engineering realizes a reliable and direct measurement of a drop of the sample from 0.3mL. Use sampling sheet (sold separately) to measure down to 0.05mL or more. Unique sensor mechanism realizes direct measurement of solid, viscous, powder samples. No need for a beaker to calibrate or measure. Just drop the standards and sample on the flat sensor, saves you time and minimize wasting your precious sample. This lightweight, pocket-sized meter is suitable for research and industrial applications in diverse fields.
