Tough and Easy-to-Use Handheld pH/ORP Meter
Can Measure pH and ORP Stably and Accurately
Our long-selling Personal pH/ORP Meter is renewed as a Portable
pH/ORP Meter with improved ease of use.
The pH/ORP portable meter can be calibrated using installed
standard solutions data. It’s automatic temperature compensation
and supportive functions enables accurate measurements. The sensor
has a plastic body to prevent accidental damage.
With the ability to attach sensors to the main unit, our Portable
pH/ORP Meter is designed for your convenience, making it easy to
carry around and use whenever and wherever you need it.
The large backlit display on the main screen shows measured values,
stability check signs, and electrode sensitivity indicator
functions, providing an easy-to-read collection of information to
support measurements.
The tough design makes it suitable for water quality control and
research applications, as well as for validating inline pH/ORP
analyzers and for grab-sample analysis.
Features
- Large, Backlit, Easy-to-Read Display
The letters are large and easy to read in the dark and daylight.
- Stability Check Function for Accurate Calibration/Measurement
It informs you when the measurement has stabilized and allows you
to calibrate/measure with the correct values.
- Electrode Sensitivity Level Indicator Function Visualizes the State
of the Detector
The sensitivity of the connected detector is displayed using
easy-to-understand icons based on the calibration data, which helps
you to know when to replace the sensor. - Durable Plastic Sensor and Build-in Sensor Holders
It can be taken out and measured immediately. Less bulky and
convenient to carry. - Excellent Grip, with a Stand on the Back
It features a easy-grip shape, ensuring it won't slip or drop, and
can be easily measured with one hand. - Various Buttons for Ease of Use
The interface is intuitive and easy to understand, with calibration
mode/measurement mode/data display mode switchable at the touch of
a button.
