Application Importance The measurement of pH in agricultural activities is very important due to the influence it has on the growth of the plant. Soil can be acid, neutral or alkaline, according to its pH value. Most plants prefer a pH range from 5.5 to 7.5; but some species prefer more acid or alkaline soils. Nevertheless, every plant requires a particular range of pH for optimum growth. Specifications HI12923 Description pH electrode Reference single, Ag/AgCl Junction ceramic, triple / 40-50 µL/h Electrolyte KCl 3.5M + AgCl Max Pressure 0.1 bar Range pH: 0 to 12 Recommended Operating Temperature -5 to 70°C (23 to 158°F) - LT Glass Type LT (low temperature) Tip /Shape conic (12 x 12 mm) Temperature Sensor yes Amplifier yes Body Material glass Cable coaxial; 1 m (3.3’) Connection quick connect DIN HI12923 pH / Temperature Probe for Soil The HI12923 pH electrode that is supplied with the HI98168 is uniquely designed with a conical tip and a triple ceramic junction for improved performance in soils that have a low moisture content. The probe has a built in amplifier to reduce noise from humidity that can effect the probe connection to the meter. The HI12923 connects to the HI98168 with a quick-connect, waterproof DIN connector, allowing for a secure, nonthreaded attachment. Refillable As electrolyte is lost over time it can be replenished to extend the life of the electrode. Triple ceramic junction The outer reference has three ceramic frits that allow electrolyte to flow at a high rate from the inside of the probe to the outside. A higher flow rate allows for a pH measurement of soil with low moisture. Conical Tip The conical tip is made of durable low temperature glass and allows for direct measurement in soils. In the case any rocks are present an auger is provided to make a hole for the probe. Quick Connect DIN Connector This secure waterproof connector allows for a single cable to be used for both pH and temperature measurements. 2 pH 2.101 www.hannainst.com | portable
