Hanna Instruments High Range pH Meter with ±0.01 pH Accuracy, 0.01 pH Resolution, 0 to 14 pH Measurement Range, 60 HI-991301

Hanna Instruments HI-991301 is a high range handheld pH meter designed for precise environmental and industrial water testing applications. It features a ±0.01 pH accuracy and 0.01 pH resolution for measurements from 0 to 14 pH, making it suitable for a wide variety of aqueous testing conditions.

This versatile meter integrates a multi-parameter probe capable of measuring pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature simultaneously. The probe is housed within a rugged, waterproof (IP67) plastic sheath reinforced with a rubber cable and stainless-steel DIN connector, ensuring durability in field environments.

The HI-991301 includes automatic temperature compensation to improve measurement accuracy under varying temperatures up to a maximum of 60 °C. Users can select EC/TDS conversion factors and adjust the conductivity temperature coefficient via simple controls. The large, easy-to-read LCD display shows measurement parameters clearly and provides battery status indicators including low battery warnings.

Powered by three AAA batteries, this meter offers approximately 600 hours of continuous use. The device incorporates auto calibration and a straightforward two-button operation to facilitate quick measurements without complex setup.

Typical industrial and agricultural applications include greenhouse irrigation monitoring, hydroponic system management, and assessment of groundwater quality for nutrient pollution due to agricultural runoff.

The HI-991301 is supplied complete with a multi-parameter probe, batteries, a detailed instruction manual, and a hard carrying case for safe transport and storage. For extended probe replacements, model HI-1288 is recommended.
