Product Description

The Hanna HI98107 pH Tester is a compact digital instrument for measuring pH and temperature in water and compatible aqueous samples. It displays the pH value and sample temperature at the same time, making routine water-quality checks easier in the laboratory or at the testing location.

The pHep HI98107 measures from 0.0 to 14.0 pH with 0.1 pH resolution. Its integrated temperature sensor automatically compensates the pH reading between 0 and 50°C, reducing the need for manual temperature correction.

The tester supports automatic one-point or two-point calibration using recognised pH 4.01, 7.01 and 10.01 buffer solutions. A stability indicator helps the user know when the reading is ready to record, while the two-button design keeps operation straightforward.

Product Overview

pH indicates whether a water sample is acidic, neutral or alkaline. Routine pH monitoring is important because unsuitable pH can affect drinking-water acceptability, aquarium health, pool treatment, pond conditions and many water-based processes.

The HI98107 combines a glass pH electrode, exposed temperature sensor and digital display in one handheld tester. The user immerses the sensing end in the sample, stirs gently and waits for the stability indicator to disappear before recording the result.

Key Benefits

Portable Testing

The slim pocket-sized body allows users to perform pH checks at the sample location without carrying a separate benchtop meter.

pH and Temperature on One Display

The multi-level LCD shows both the pH value and sample temperature, allowing the user to review the two measurements together.

Automatic Temperature Compensation

The integrated temperature sensor automatically adjusts the pH measurement for sample temperatures between 0 and 50°C.

Straightforward Calibration

The tester recognises standard pH 4.01, 7.01 and 10.01 buffers and automatically accepts calibration after the reading stabilises.

Reading Stability Guidance

A stability indicator remains visible while the value is changing and disappears when the reading is ready to record.

Long Battery Operation

The official manual states approximately 800 hours of continuous operation from one CR2032 battery, subject to use conditions.

Who Should Buy This Product?

• Water-testing laboratories and quality-control teams
• Aquarium owners and maintenance professionals
• Pool and spa maintenance teams
• Fish farms, ponds and aquaculture operators
• Water-treatment and filtration service providers
• Hydroponic growers and nutrient-solution users
• Schools, colleges, universities and research laboratories
• Environmental field technicians
• Industrial and institutional procurement departments requiring portable pH checks

Usage and Handling Summary

Read the supplied instruction manual before first use. The following summary covers the standard preparation, calibration and measurement steps.

• Remove the protective cap and inspect the electrode tip before use.
• If the electrode is dry, soak the bottom section in Hanna HI70300 storage solution for at least 30 minutes. Initial conditioning may require several hours.
• Rinse the electrode tip with purified, distilled, deionised or reverse-osmosis water before placing it in a buffer or sample.
• Calibrate the tester with fresh buffer solution. For two-point calibration, use pH 7.01 first and then pH 4.01 or 10.01 according to the expected sample range.
• Press the ON/OFF button and immerse the sensing end in the sample without exceeding the recommended immersion level.
• Stir gently and wait until the stability indicator disappears.
• Read the pH value on the primary display and the sample temperature on the secondary display.
• Rinse the electrode between different samples to reduce cross-contamination.
• After use, place several drops of HI70300 storage solution in the protective cap and replace the cap securely.

Handling and Maintenance Precautions

• Do not store the electrode in distilled or deionised water because this can damage or shorten electrode performance.
• Use fresh calibration buffers and do not return used buffer to the original container.
• Avoid touching or scratching the glass electrode area.
• Keep the cloth junction and sensing area clean and hydrated.
• Use the specified CR2032 battery and dispose of used batteries according to local requirements.
• Do not use or store the tester in hazardous environments unless the supplied documentation confirms suitability.

Limitations and Important Considerations

• The HI98107 measures pH in water and compatible aqueous samples. It is not designed to measure dry soil, solid materials or air directly.
• The tester has 0.1 pH resolution. Applications requiring 0.01 pH resolution should use a higher-resolution instrument such as an appropriate alternative model.
• Accurate results depend on regular calibration, fresh buffers, correct electrode hydration and proper cleaning.
• A dry, dirty or clogged electrode can cause slow, unstable or incorrect readings.
• Purified water may be used to rinse the electrode, but it must not be used as the electrode storage liquid.
• Very viscous, oily, high-solids or chemically aggressive samples may require a specialised electrode or instrument. Contact Inaya Scientific for confirmation.
• The official Hanna instruction manual lists ±0.1 pH accuracy and approximately 800 hours of battery life. Product webpages or local listings may show revision-dependent values, so confirm the specification of the supplied unit before procurement.
• Formal compliance or regulatory testing may require a calibrated laboratory instrument, documented procedures and traceable standards.
