waterproof pH meter

Probe Condition

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.

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.

Your measurements require detailed attention; so should your electrode. The HI991001 Portable pH Meter features a replaceable HI12963 probe that has been carefully designed specifically for pH measurements encountered in manufacturing and environmental testing protocols.

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.

Integrated Temperature Sensor

A built-in temperature sensor ensures fast, accurately compensated readings even during sudden temperature fluctuations.

Cloth Junction

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.
