The HI-99121 portable pH meter, together with HI-12923 pH electrode, is designed to measure pH in soil or soil slurries.
The HI-99121 is a lightweight, portable pH and temperature meter. It features a two-button operation system and is simple to use. It has a waterproof and compact casing, large dual-line display, and automatic pH calibration at one or two points.
Benefits
HI-12923 has a conical rugged tip. It has a built-in temperature probe for temperature compensated pH readings and an integrated pre-amplifier to provide measurements impervious to noise and electrical interferences.
The HI-721319 auger for ground penetration is supplied to loosen the soil prior to any measurements being taken. The use of the auger is recommended to prevent scratching to the pH glass.
For best results, it is recommended that soil tests be carried out using a prepared soil slurry using the HI-7051 soil sample preparation solution, rather than direct ‘in the field' measurements - although this is possible following the instructions and use of the included auger.
Each meter is supplied complete with:
