Material #: 30671568
Straight to the point
SD23 pH/conductivity meter with InLab Pure-Pro ISM pH/temperature sensor and InLab 741 ISM conductivity/temperature sensor for measurements in pure water. Includes an efficient electrode arm.
Mastered in no time
Large color touchscreen provides direct measurement and easy data entry. Instructions guide users through the sensor calibration process.
Tracks your records
The instrument stores data like timestamp, sample and sensor ID with every measurement and prints or exports records automatically.
Tough enough
Closed connector compartment and replaceable cover keep the instrument safe from dust and spills, even with sensors attached (IP54 in-use).
Pure water specialist sensors
InLab Pure-Pro ISM and InLab 741-ISM are specialist sensors for pH, temperature and conductivity measurements in pure water. They are specifically designed to achieve high accuracy in this challenging sample.
Electrode arm for efficient operation
The EasyPlace electrode arm makes placing the sensor in the sample or buffer container easy. Dedicated positions for cleaning and storage support correct sensor handling. Vertical and horizontal movements facilitate precise positioning, even with one hand.
Protect critical settings
A two-level user management protects the most important settings. Operators retain the flexibility to individually set preferences like language and screen brightness.
Display adapts to your needs
View detailed measurement information on one measurement screen – or focus on the result only and maximize readability with the uFocus mode.
Two Parameters in One Device
Measure pH and conductivity with one instrument – simultaneously or separately as the application requires.
