Boron Chemical Test Kit for Irrigation Water

The HI38074 is a titration-based chemical test kit that determines the boron concentration in irrigation water within a 0 to 5 mg/L (ppm) range. The HI38074 is supplied with all of the necessary reagents and equipment to perform the analysis, including the HI98103 Checker pH meter. The HI98103 Checker pH meter is used for sample preparation and for the determination of the pH titration endpoint. The HI38074 contains enough reagents for perform 100 tests.

Features at-a-glance

Complete setup

• All required materials are included with the test kit, such as the sample beaker, plastic pipettes, pH adjustment reagents, and pocket pH meter.

High resolution

• Readings from 0 to 5 mg/L are determined to 0.2 mg/L resolution.

Replacement reagents available

• There is no need to buy a new kit when reagents are exhausted. The HI38074-100 reagent set can be ordered to replace the reagents supplied with the kit. This reagent set comes with 1 (30mL) dropper bottle of HI38074A-0, 1 (30mL) dropper bottle of HI38074B-0, 1 (100mL) bottle of HI38074C-0, 100 packets of mannitol powder, and 1 (100mL) bottle of HI38074E-0.

Significance of Use

Boron is one of the micronutrients essential for plant growth. It may be present naturally in water, or it may find its way into a watercourse through industrial waste effluents. Boron in excess of 2.0 mg/L in irrigation water can be detrimental to plant growth, and some plants may even be adversely affected by concentrations lower than 1.0 mg/L.
