Hanna Instruments Combo pH & ORP Waterproof Meter

Model HI 98121

The HANNA HI 98121 is an advanced function combination waterproof tester designed to simultaneous measure pH and ORP levels. A temperature reading is continuously displayed on the dual level LCD.

The HI 98121 pH electrode is closely positioned to an encapsulated external stainless steel sensor. This new design allows for quicker, more accurate readings. A new stability indicator also ensures reliable readings.

The HI 98121 works is powered by commonly available batteries. An LCD indicater displays the percentage of remaining battery life. The fiber junction can be easily removed and replenished. The pH electrode, when spent, can quickly be replaced with the tool included with the meter.

This meter is Ergonomically designed for ease of use, and will float if inadvertently dropped into water.
