HI-991300 Waterproof pH, EC, TDS and Temperature Meter with Advanced Features
Hurry up, only 7 items left in stock.
The Hanna HI-991300 is a portable, waterproof pH, EC, TDS and temperature meter designed for water treatment professionals, boiler technicians, maintenance engineers and industrial water quality specialists.
Ideal for monitoring boiler water, heating systems, cooling circuits, treated water and industrial process water, the HI-991300 measures four important water parameters using a single multiparameter probe. Monitoring pH and conductivity helps assess water quality and identify changes that may affect system performance, corrosion and scaling.
Its combined probe measures pH, conductivity, TDS and temperature, while automatic temperature compensation helps ensure consistent EC and TDS readings. The selectable EC-to-TDS conversion factor allows measurements to be adapted to different applications.
The IP67-rated waterproof housing makes the instrument suitable for demanding working environments. Its large multi-level LCD displays readings clearly, and simple two-button operation makes routine measurements straightforward.
Combining versatile measurements with a rugged, portable design, the HI-991300 is a practical tool for water quality control in heating, cooling and industrial water systems.

Description
Description
The HI-991300 meter features two operation button and is simple to use. All operations and settings, including calibration buffers and temperature scale selections, are made through these two buttons. It has a waterproof and compact casing rated for IP67 conditions and a large tri-line display. The meter has automatic pH calibration at one or two points and a single conductivity calibration. Other user selectable features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients from 0.0 to 2.4% for better conductivity or TDS solution temperature compensation. The meter is supplied with a multi-parameter probe specifically designed for this meter.

About the HI-12883 probe
The HI-12883 multi-parameter probe, incorporates a domed shaped pH bulb rated from 0-13 pH, a single junction Ag/Cl reference electrode with gelled electrolyte and a retractable cloth wick junction, a graphite EC/TDS cell, and a temperature sensor in one convenient, rugged polypropylene body. In addition, to ensure against interference from transient electrical noise to pH, a solid-state pre-amplifier is integrated into the probe. The probe is rated from 0 to 50°C.
