NPK Nutrient Meter

The NPK Meter allows growers to test Nitrogen, Phosphorus and Potassium (NPK Measurement) in minutes with one probe and just 50ml of sample solution. This accurate, instant test means is simple to operate and avoids the need to send samples to the test laboratory with all of the cost and delay that causes so much frustration. The meter can be calibrated with one Multi-Cal Standard solution and displays all three parameter results in ppm on the screen.

This is a Meter Only option and will require An NPK Sonde to make any measurements. You will also need Solutions for Calibration and measurement   

The Sonde has three sensors and a reference electrode which can be replaced individually when the diagnostics feature indicates the need. This result can be stored in the internal memory and downloaded to Excel for storage and manipulation. Each measurement is Date stamped and has a user ID field to easily identify sample results.

Features include:

• Direct Readout of NPK ppm in Minutes
• 1 or 2 Point Calibration
• Diagnostic Mode
• 200 Hours Battery Life
• Backlit Display
• Data Logging & Internal Storage
• Data Output via Micro USB
• Very low cost per test
• Easy to use

The NPK meter can also be used for monitoring Run-off from Coir bags in Polytunnels, River water and other environmental applications To measure the NPK in soils there is a sample preparation step to get an aqueous sample. You cannot dip the probe directly into the soil. The NPK can be directly determined to establish soil health and calculate the Fertilizer Kg/Hectare requirement.
