Hannab NPK Soil Chemical Test Kit (25 tests each)

The HI3896 NPK Soil Chemical Test Kit is a chemical test kit for determining commonly monitored soil parameters: pH, nitrogen (N), phosphorus (P) and potassium (K). The kit uses colorimetry and turbidimetry and is supplied with all necessary reagents and equipment to perform tests, providing a fundamental tool to assess characteristics related to soil quality. It is intended for quick, on-site or bench-top evaluation of soil pH and the three primary macronutrients for plant growth.

Key Features:

• Parameters measured: pH, Nitrogen (N), Phosphorus (P), Potassium (K)
• Number of tests: 25 tests for each parameter
• pH measurement: colorimetric (pH indicators), range 4.0 to 9.0 pH, resolution 1 pH
• Nitrogen method: NED colorimetric; Phosphorus method: ascorbic acid colorimetric; Potassium method: tetraphenylborate turbidimetric
• Kit contents included: extraction solution (2 × 120 mL), pH indicator (70 mL), 75 powder packets (25 each for N, P, K), test tubes, pipettes, spoon, brush, color comparison cards, graduated card and handbook

Advantages:

• Pre-made, pre-measured reagents for ease of use and faster testing
• All reagents marked with expiration date and lot number for traceability
• Complete setup includes all required materials so no additional supplies are needed to begin testing
• Replacement reagents available so the kit can be replenished without purchasing a new kit
