This manual introduces the use of the HI 38074 Irrigation Water Boron Test Kit, including the instrument composition, usage steps, and precautions.
This document is an instruction manual for the Hanna Instruments HI 38074 Boron Test Kit, designed for analyzing irrigation water. The kit includes various reagents (HI 38074A through E), Mannitol powder, a pH Checker meter, and other accessories necessary for performing titration analysis.
| Range | 0 to 5 mg/L (ppm) as Boron |
|---|---|
| Smallest Increment | 0.2 ppm Boron |
| Analysis Method | Titration |
| Sample Size | 50 ml |
| Number of Tests | 100 |
Boron is a micronutrient essential for plant growth, but concentrations over 2.0 mg/L are detrimental to many plants.
If the pH does not change after adding the Mannitol reagent packet, boron is considered absent.
The sample must be pretreated by heating it in a microwave oven to eliminate carbonate interference.
