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 HI99131 Plating pH Meter features a replaceable probe that has been carefully designed specifically for the pH analysis of plating baths.

Titanium Body

The titanium body protects your pH electrode from accidental breakage, making it ideal for measurements in plating baths. It also serves as a matching pin to reduce problems caused by electrical currents.

Flat Glass Tip

The recessed flat tip bulb is easy to clean and prevents solids in plating solutions from collecting on the sensor, reducing maintenance.

PTFE Junction

This electrode has a unique clog resistant junction that enhances both probe life and accuracy. Due to its chemical advantages, PTFE is widely used in industrial applications.

We believe that buying a meter should be simple. Your Plating pH Portable Meter is equipped with everything you need for successful testing right out of the box.

Electrode Cleaning Solution

Your Plating pH Portable Meter comes with cleaning solution that has been engineered to keep your electrode free from debris found in soils. 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.
