Hanna HI99171 Leather and Paper pH Portable Meter

Description

Introducing the HI99171 Leather and Paper pH Meter

The Hanna Instruments HI99171 is a sophisticated, lightweight, and portable pH meter engineered specifically for the direct, non-destructive measurement of pH on flat surfaces such as leather and paper. This innovative device comes with a purpose-built HI14143 pH electrode that features a flat tip, a low-resistance pH glass, and an open junction design. This unique combination ensures optimal contact with the sample, rapid response times, and stable, repeatable measurements, even in challenging environments. The meter’s design focuses on simplicity, featuring a two-button operation, a large dual-line LCD display for simultaneous pH and temperature readings, and automatic calibration for user convenience.

A Specialized Probe for Precision

At the heart of the HI99171’s performance is the specialized HI14143 probe. This electrode is a key differentiator, providing optimal contact between the sensor and the sample surface due to its flat tip. Its low-resistance pH glass allows for swift and accurate responses, which is crucial when dealing with sensitive materials. The open junction design further enhances its reliability by preventing clogging from organic materials often present in leather and paper, ensuring a more stable measurement with reduced maintenance requirements. The integrated pH sensor preamplifier provides stable readings even in electrically noisy environments. This careful design ensures that measurements are both highly accurate and reproducible.

Broad Applications in Industry and History

The HI99171 is not just a tool; it’s a vital instrument with broad applications across various fields. For historians, it provides a crucial and non-destructive method for determining the pH of valuable or irreplaceable documents, as the pH of paper is a key indicator of its permanence. In the production of cartons and paper for food packaging, pH measurements serve as a useful gauge for product compatibility. Leather technicians rely on this meter during production to preserve fiber structure and prevent damage, using the readings to optimize dyes, coatings, and softening agents. These specialized applications highlight the meter’s ability to deliver high accuracy and repeatability without destroying the sample.

Built to Withstand the Real World

Durability is a key feature of the HI99171. With an IP67 rating, this meter is designed to withstand the knocks, drops, and spills of real-life use. It is protected against dust and water intrusion from any direction, ensuring top performance in any environment. The portable design makes it comfortable to hold and easy to use for on-the-go testing. Its multilevel LCD display provides a clear view of pH and temperature readings from any angle, while the dual-button operation streamlines the entire testing process. The robust build quality and thoughtful design make this meter a reliable partner in any application.

Intelligent Features for Ease of Use

The HI99171 incorporates several intelligent features to simplify operation and prolong its lifespan. The device offers automatic calibration at one or two points, utilizing either standard or NIST buffer sets. An on-screen indicator provides visual confirmation of the probe’s condition, helping users determine when to clean or replace it. A low battery indicator warns the user when the power is below 10%, and the meter will automatically shut down to prevent erroneous readings. Additionally, the auto-off function can be set to 8 or 60 minutes, or it can be disabled, conserving battery life for extended use.

A Convenient and Complete Package

Purchasing the HI99171 is a simple process, as it comes with everything you need to begin testing immediately. Each meter is supplied in a rugged carrying case and includes a HI14143 probe, pH 4.01 and 7.01 buffer sachets, cleaning solution for cellulose deposits, a preparation solution for solid or semi-solid samples, and all necessary batteries. The single-use sachets ensure fresh buffer for each calibration, and the cleaning solutions are specifically engineered to keep the electrode in optimum condition. This all-inclusive package ensures that users can get started with accurate and reliable measurements without any additional purchases.
