Description
Description "Horiba LAQUAtwin Nitrate Ion (NO3-) Tester for crops, in carrying case with 5 Pipettes, Crop sample press, 3 cups"
Precise Nitrate Tester for Plants – Mobile NO₃⁻ Analysis On-Site
Horiba Nitrate Ion Pocket Tester Kit for fast and accurate on-site results
The Horiba LAQUAtwin Nitrate Ion Hand Tester (NO3-11C) in its practical analysis kit is your mobile laboratory for reliable determination of nitrate ions and temperature in plant sap samples. With a wide measurement range of 6 to 9900 ppm NO₃⁻ and automatic temperature compensation, the device provides fast and accurate results. The ion-selective electrode ensures precise NO₃⁻ measurements, while the digital backlit display allows quick and easy reading of values.
Mobile nitrate analysis kit for plants, water, and environmental monitoring
The kit contains the handheld tester, five pipettes, three measuring cups, a plant sample press, standard solutions, and sampling sheets. This setup allows for rapid and reproducible analysis of plant sap without the need for additional laboratory equipment.
The device is dust- and waterproof, features automatic standard recognition, Auto-Stabil and Auto-Hold functions, and has a long battery life, making it ideal for mobile use in the field, greenhouse, or laboratory.
Why nitrate measurement in plants is important – and why a mobile kit is ideal
Nitrate content in plants is a key indicator of nutrient supply, plant growth, and agricultural product quality. Excessively high or low nitrate levels can negatively impact yield, plant quality, and environmental compatibility.
A mobile nitrate hand tester allows direct analysis of plant sap on-site, without time-consuming laboratory procedures. Fertilization and irrigation measures can be precisely adjusted, and over- or under-supply can be detected early. The Horiba LAQUAtwin NO3-11C provides a precise, fast, and practical solution for this purpose.
Typical applications for the Horiba Nitrate Analysis Kit
- Aquaculture and coral monitoring
