Pocket Nitrate meter featuring HORIBA unique flat sensor technology (Nitrate Ion Selective Electrode) that allows measurement from a drop of sample as little as 0.3 ml.


⚫ This Nitrate meter is ideal to measure solid samples such as soil or micro samples from plant sap (when only a few drops of plant sap can be extracted).

The meter can also be immersed in liquid samples (i.e. water samples or nutritive solutions).


⚫ HORIBA LAQUAtwin meter NO3-11 is fully waterproof (IP-67) and can deliver instant results, which makes it a perfect meter for easy and quick field-testing. The wide measurement range allows to measure most samples directly without having to do a dilution or filtration.


⚫ LAQUAtwin Nitrate meter delivers precious information regarding the concentration of Nitrate or Nitrogen (NO3-N) - one of the most important nutrients in soil and plant tissue (sap extract) as well as nutritive or hydroponic solutions.


⚫Combined with TestAgro reference tables, this meter helps growers to quickly identify deficiencies in the field without having to wait for laboratory results or observe the visual effect on the pant. Growers can check the nutrition level of the crops and adjust the fertilization strategy based on meter results.

The meter can also be used to verify if the nutritive solution mix has the desired nitrogen concentration.


⚫Calibrate this Nitrate NO3-11 meter regularly with Nitrate Calibration Solution Set 150 and 2000 ppm.


This meter includes: plastic case • 150 & 2000 ppm calibration solutions (14ml each) • 2 x CR2032 batteries • dropper • instruction and quick manuals.
