Envco – Environmental Equipment

• Waterproof*
• Automatic calibration function (selection of 1-point, 2-point calibration)
• Wide measuring range
• Flat sensor enables measurements of small sample volumes (0.3mL)
• Special setting modes
• (temperature measurement, voltage measurement, compensation function etc)
• Selectable analysis of NO3- or NO3- -N
• Selectable units (ppm, mg/L, kg/10a)

* The meter cannot be used totally submerged underwater

Nitrogen is essential for healthy and high yielding crops. The current cost of nitrogen fertilizers requires growers to make well educated and accurate decisions regarding when and how much nitrogen is needed. Immediate in-field testing determines how much nitrate is already present, minimizing the possibility of wasted fertilizer.

Measure nutrient solutions, soils, greenhouse soilless media, water samples and tissue sap. Includes batteries, case and calibration standards.
