The HI99121 is the perfect portable pH meter for soil testing. With the HI99121 pH meter and the HI12923 direct soil pre-amplified pH and temperature probe, users can measure soil pH directly or after preparing a soil suspension with deionized water. The HI12923 electrode features a durable, conical tip that can be used directly in the soil. A plastic awl is supplied for piercing and loosening the soil before measuring with the sensor. Use this tool to avoid scratching the pH-sensitive glass on nutrient crystals or small stones.
