Hanna HI98120 ORP/Temperature Tester

Description

Rugged Waterproof Design for Ultimate Field Reliability

The Hanna HI98120 ORP/Temperature Tester is engineered to deliver uncompromising performance in the most challenging environments. Its waterproof housing, rated IP67, ensures that accidental immersion in tanks, swimming pools, or any body of water does not damage the internal electronics. This intelligent design not only provides maximum protection, but also features a buoyant body that floats if dropped, preventing loss and enabling quick recovery in the field. The unit’s construction is completely sealed against dust and moisture intrusion, making it dependable for industrial, laboratory, and outdoor applications. The durable casing and robust internal build combine to create a pocket-sized meter that handles demanding operational conditions without sacrificing precision or usability. Professionals benefit from this endurance when conducting ORP and temperature measurements in diverse surroundings, from wet chemical processing lines to hygienic food plant floors.

Replaceable ORP Electrode with Cartridge Innovation

A major advantage of the HI98120 is its replaceable HI73120 ORP electrode, designed in a cartridge format. Unlike conventional designs that incorporate fragile connector pins prone to bending or breaking, Hanna’s stainless steel round connector solution provides reliable contact and long service life. The electrode also integrates an extendable cloth junction — by simply pulling out 3 mm (1/8″), users can renew the junction to clear clogs and regenerate responsiveness. This feature is invaluable for professionals requiring quick recovery of measurement accuracy, especially when working with solutions prone to fouling. Maintenance is streamlined to minimize downtime, meaning laboratories, pools, and plating facilities can maintain continuous monitoring schedules without costly delays. Replacement can be performed easily on site without specialist tools, reducing overhead and equipment turnaround time while preserving consistent measurement quality.

High-Precision ORP and Temperature Measurement System

The HI98120 offers comprehensive measurement capabilities with a broad ±1000 mV ORP range, a fine resolution of 1 mV, and an accuracy of ±2 mV. Factory-calibrated for immediate use, it saves setup time while ensuring accuracy standards are met right out of the box. The integrated exposed stainless steel temperature probe ensures rapid, precise temperature readings ranging from -5.0 to 60.0°C (23.0 to 140.0°F) with ±0.5°C accuracy. This dual functionality is key for processes where redox potential and temperature influence each other, such as in chemical dosing systems or fermentation control. The ability to capture two critical parameters with one instrument not only simplifies workflow but also improves operators’ situational awareness, enabling them to make faster and more informed adjustments.

Key Applications Across Multiple Industrial Sectors

The HI98120 targets a broad spectrum of professional uses where monitoring the oxidation-reduction potential is essential. In swimming pool maintenance, it provides accurate tracking of chlorine and ozone disinfection efficiency. In food processing, it ensures safety by verifying sanitation levels and rinse water conditions. Boiler and cooling tower operations benefit from precise ORP readings that help prevent corrosion and scale formation. In metal plating wastewater management, its measurements verify effective reduction of hazardous hexavalent chromium to safer trivalent chromium using bisulfite. These applications demand continuous high-quality data collection, and the HI98120 delivers on this requirement through its precise ORP measurement capability and robust construction, enhancing safety, compliance, and production quality across industries.

Advanced Display Features Enhance User Interaction

The HI98120’s LCD is designed to communicate measurement status clearly, featuring a stability indicator that disappears once readings stabilize, allowing confident data recording. A HOLD function lets users freeze readings for convenient documentation. Upon startup, the display reveals battery percentage, empowering users to plan timely battery changes and avoid unexpected downtime. These intelligent design elements optimize field usability, making the tester friendly even for operators with limited technical background. Whether used in a high-speed manufacturing line, a remote environmental monitoring station, or during routine pool maintenance checks, visual clarity and intuitive controls reduce operational error risk and help achieve consistent measurement results with minimal training.

Power Efficiency and Long Operational Lifespan

Energy management in portable instruments directly impacts operational productivity. The HI98120 employs an auto-off function to shut down after 8 minutes of inactivity, significantly conserving battery life in scenarios where users may be temporarily distracted. Powered by four 1.5V batteries, the unit offers approximately 250 hours of continuous use, meaning months of field measurements without replacements under standard duty cycles. The balance between operational uptime and portability ensures uninterrupted monitoring programs. Coupled with its replaceable electrode design, the HI98120 offers one of the most sustainable user experiences in its class, reducing waste while maximizing return on investment over its service life.

Complete Package Including Test Solutions and Tools

Every HI98120 is supplied ready for professional deployment, packaged with the HI70022 ORP test solution (470 mV, six sachets), the HI73120 electrode, and the HI73128 electrode removal tool. Four 1.5V batteries are pre-installed, and an instrument quality certificate plus instruction manual ensure users can start measuring immediately with confidence. This inclusive bundle minimizes the need for separate accessory sourcing and assures that calibration and maintenance can be performed on schedule. Laboratories, municipal water treatment plants, and service companies benefit from faster integration into daily operations, reducing the risk of delays and measurement inconsistencies due to unavailable consumables or tools.
