To measure the pH of soil as a slurry it is recommended to use a mixture of 1 part soil to 1 part water. The slurry is allowed to rest for 10 minutes so that the solids will settle out and the pH of the liquid above can be measured.\u003c\/p\u003e\n\u003cp\u003eThe HI-98118 is an advanced meter while maintaining simplicity. The front of the meter has two buttons. One is for turning the meter on and off while the other is used to enter the calibration mode. There is a third button in the battery compartment that allows the user to customise the meter to their preference. Customisation includes temperature readout in °C or °F, automatic shut off selectable from 8 minutes, 60 minutes or disabled, and lastly the choice of using Hanna's Quick Cal pH\/EC standard or traditional buffers values of pH 4.01, 7.01 and 10.01.\u003c\/p\u003e\n\u003cp\u003eThe electrode features a unique extractable cloth junction.\u003c\/p\u003e\n\u003cp\u003eThe reference junction of a pH electrode, also known as a salt bridge, provides an electrical pathway between the internal reference cell and the sample.

With the Hanna extractable junction a small portion of 1\/8\" is extracted or pulled to expose a clean surface. With the junction renewed the clogging is cleared allowing the meter to still be used.
