Specification :

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.

The newly designed Cardy Nitrate Meter is a waterproof, pocket-sized meter that accurately measures samples as small as 0.3 mL. Sensor is stored dry and is easily replaceable.

Measure nutrient solutions, soils, greenhouse soilless media, water samples and tissue sap.

Includes batteries, case and calibration standards.
