Probe Condition
An on-screen indicator provides visual confirmation that your probe is working at its best.
Low Battery Indicator
The included batteries provide 1200 hours of continuous use. When the battery level is below 10%, a warning symbol will blink to indicate low battery condition. When low battery power may affect your results, the meter will shut down to avoid erroneous readings caused by low battery level.
Automatic Shut-off
The auto-off feature can be set to shut the meter off at 8 or 60 minutes, or it can be disabled so that the meter continuously stays on. The auto-off feature prolongs battery life for peace-of-mind and energy savings if the meter is accidentally left on.
Built to be Durable
Designed to withstand the knocks, drops, and spills of real life, the new IP67 body ensures top performance in any environment. These meters are protected against dust and water intrusion from any direction.
Portable Design
Made to fit comfortably in your hand for on-the-go testing, the multilevel LCD display provides at-a-glance readings of pH and temperature from any angle and dual button operation streamlines the testing process for any user.
Quick Connect Probe
A Quick Connect DIN connector makes attaching and removing the probe simple and easy. The rubber coating protects the cable and provides a water-tight seal without twisting.
Your measurements require detailed attention; so should your electrode. The HI99171 Leather and Paper pH Portable Meter features a replaceable HI14143 probe that has been carefully designed specifically for the pH analysis of flat surfaces, such as leather or paper.
Glass Body
A glass body is easy to clean, is chemically resistant, and quick to reach thermal equilibrium for a faster, more stable measurement.
Flat Tip
The flat tip requires minimal sample immersion, allowing you to measure moist solid samples or small sample volumes.
Open Junction
The open junction design reduces clogging from organic materials found in leathers and paper for a more stable pH measurement and reduced maintenance.
We believe that buying a meter should be simple. Your Leather and Paper pH Meter is equipped with everything you need for successful testing right out of the box.
Cleaning Solution for Ink Stains (2)
Your Leather and Paper pH Meter comes with cleaning solution that has been engineered to keep your electrode free from debris found in dyes and inks. This concentrated combination of detergents cleans your meter quickly and effectively so that your meter stays in optimum condition.
pH 4 & 7 Buffer Sachets
When performing a pH calibration it is important that the correct buffers are used. We include some start buffers to get you going. The single-use sachets are individually sealed so you use fresh buffer each time you calibrate.
Preparation Solution for Solid or Semi‑solid Samples
The HI70960 sample preparation solution is used to prepare solid or semi-solid samples for testing. If only a solid sample is available, slice it very small and add a few drops of HI70960 to make the sample wet. This will ensure proper contact with the pH electrode for accurate measurements.
