MT SevenDirect SD23 pH / Conductivity Meter

Manufacturer: Mettler Toledo

The SevenDirect SD23 is an accurate and flexible meter for the determination of pH and conductivity – either separately or simultaneously. The instrument is delivered with an EasyPlace sensor arm. Large colour touchscreen provides direct measurement and easy data entry. Instructions guide users through the sensor calibration process. The instrument stores data like timestamp, sample and sensor ID with every measurement and prints or exports records automatically. Closed connector compartment and replaceable cover keep the instrument safe from dust and spills, even with sensors attached (IP54 in-use)
