An on-screen indicator provides visual confirmation that your probe is working at its best.
Low Battery Indicator
The included batteries provide 1400 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.
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.
Made to fit comfortably in your hand for on-the-go testing, the multilevel LCD display provides at-a-glance readings of pH, ORP, 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 HI991003 Portable pH/ORP Meter features a replaceable HI12973 probe that has been carefully designed specifically for pH and ORP measurements encountered in a variety of manufacturing and environmental testing protocols.
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.
Platinum ORP Sensor
Provides the best response over a wide range of applications.
When readings appear sluggish, simply pull out some of the cloth material from out from its position t renew the junction with an uncontaminated, fresh surface.
We believe that buying a meter should be simple. Your Portable pH Meter is equipped with everything you need for successful testing right out of the box.
General Electrode Cleaning Solution
Your Portable pH/ORP Meter comes with cleaning solution that has been engineered to keep your electrode free from debris and build up. 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.
