The Hanna HI991003P is a professional-grade, compact, and waterproof portable meter designed specifically for demanding environmental and manufacturing protocols. This versatile instrument provides simultaneous measurements of pH, ORP, and temperature, making it an essential tool for monitoring plating baths, wastewater, and swimming pool water quality. Built to withstand harsh field conditions, the meter is protected by an IP67-rated housing that is designed to float if accidentally dropped in water.

Advanced Electrode Technology

The system is supplied with the HI1297D pre-amplified pH/ORP probe. This unique electrode features a rugged titanium body that is highly resistant to aggressive chemicals, ensuring durability in industrial environments. The titanium body also acts as a matching pin, working with the built-in amplifier to virtually eliminate electrical noise from motors or rectifiers that often interferes with high-impedance pH measurements. Additionally, the probe includes an extractable cloth junction; if readings become sluggish due to clogging, simply pull out 1/8" of the junction to expose a fresh surface and restore response time.

Innovative Sensor Check™ Feature

One of the standout features of the HI991003P is the integrated Sensor Check™ technology. This allows users to determine the status of the pH electrode at any time, providing peace of mind regarding the accuracy of your data. The meter can display the electrode's mV status, allowing for a quick check of the probe's offset and slope characteristics to ensure it is performing within optimal specifications.

Simplified Operation and Long Battery Life

The meter is designed for ease of use with a simple two-button interface. A large, dual-level LCD screen clearly displays your primary measurement alongside the temperature and status indicators. Calibration is streamlined and automatic at one or two points with two selectable buffer sets. To ensure portability, the HI991003P offers an exceptional battery life of up to 1200 hours of continuous use and features a Battery Error Prevention System (BEPS) that automatically shuts the meter off if power is too low to guarantee an accurate reading.

Professional Durability

From its quick-connect DIN connector to its heavy-duty carrying case, every aspect of the HI991003P is built for the field. The meter includes a stability indicator that displays a clock icon until a steady reading is reached, and a HOLD button to freeze measurements on the screen for easy recording.
