Hanna HI98121 pH/ORP/Temperature Combo Tester

Description

Precision Measurements in Portable Waterproof Form Factor

The Hanna HI98121 pH/ORP/Temperature Combo Tester delivers unmatched versatility and reliability in a single, portable instrument. Engineered for fast, accurate, and straightforward measurements, it combines pH, ORP (Oxidation Reduction Potential), and temperature readings into one compact waterproof tester, designed to withstand demanding environments and field conditions. With its ergonomic design, the HI98121 easily fits into your hand or pocket, and even floats when placed in water, providing complete peace of mind during on-site testing. Boasting a highly precise ±0.05 pH and ±2 mV accuracy, along with 0.01 pH and 1 mV resolution, it meets the rigorous demands of professional and industrial applications without requiring separate meters. This integrated approach saves time, reduces complexity, and ensures consistent, reliable readings every time.

Advanced pH and ORP Monitoring Capabilities

The HI98121 offers simultaneous monitoring of pH and ORP levels, reducing the need for switching between instruments during routine testing. pH measurement is achieved through a replaceable HI73127 electrode, ensuring prolonged use and easy maintenance, while ORP readings rely on a durable fixed sensor built with noble metals such as pure platinum or gold, known for their resistance to oxidation or reduction and exceptional electron exchange capability. This tester’s ORP calibration is factory set, assuring accuracy straight out of the box. Automatic temperature compensation supports pH measurements across a wide range, ensuring fluctuations in environmental conditions do not hinder data reliability. The HI98121 is ideal for monitoring the acidity or alkalinity of solutions alongside their redox potential, thus helping users assess chemical reactivity, sanitation efficacy, and oxidative or reductive strength across varied environments.

Wide Range of Professional Applications Worldwide

The Hanna HI98121 is designed for a broad array of professional uses, making it indispensable for scientists, technicians, and operators in multiple fields. Its waterproof design and floating capability make it excellent for pool maintenance, where monitoring chlorine levels via ORP and pH ensures safe swimming conditions. In the food industry, it aids in sanitization verification, maintaining hygiene standards in production and processing facilities. In wastewater treatment plants, it enables operators to track redox balance and acidity, optimizing chemical treatment processes. The HI98121 is also critical in electroplating operations, where precise pH and ORP control ensures uniform metal coating. Cooling tower water treatment requires careful monitoring of parameters to prevent scaling and corrosion, a task this tester handles impeccably. No matter the environment, its accuracy and ruggedness guarantee trustworthy results for compliance, safety, and operational excellence.

User-Friendly Design for Effortless Measurement

Ease of use is a defining strength of the HI98121. Its HOLD function lets users freeze readings for easy documentation, while automatic shutdown after eight minutes of inactivity conserves battery life. The tester’s light weight at only 100 g and slim dimensions (163 x 40 x 26 mm) make it exceptionally portable, even for daily fieldwork. Battery replacement is simple, supported by a robust design that offers approximately 250 hours of continuous operation from four standard 1.5 V batteries. The automatic calibration process can be completed using one or two points and standard buffers, making large-scale testing faster and more precise. Built for convenience without sacrificing performance, the HI98121 effortlessly adapts to diverse environments, ensuring both seasoned professionals and first-time operators achieve consistent and accurate measurements.
