pH/conductivity meter, SevenDirect SD23
Robust bench top meter for accurate pH and conductivity determinations in the lab and near production.
- Large colour touch screen provides direct measurement and easy data entry
- Instructions guide users through the sensor calibration process
- Stores data, such as time stamp, sample and sensor ID with every measurement, also prints or exports records automatically
- Closed connector compartment and replaceable cover keep the instrument safe from dust and spills, even with sensors attached (IP 54 in-use)
The large colour touch screen offers direct menu access, fast data entry, and guides users through routine tasks. The instruments supports GLP compliance by storing time stamp, sample also sensor and method IDs with every measurement.
