Click to view available options
Range (pH):
-2 to 20
Description
Key Points:
- Get the information you need quickly and easily from the large, backlit graphic LCD display, which shows individual pH/mV/RmV or conductivity/TDS/salinity/resistivity results with temperature, or all results at once.
- Additional helpful information includes electrode status, time, date, sample ID, user ID and calibration points.
- Advanced features such as stability and averaging provide additional options allowing for laboratory accuracy everywhere you need it.
- Plain language screen prompts and soft keys that update for easy selection
- Multi-language interface that supports English, Spanish, French, Italian, German and Chinese
Benefits:
- Thermo Scientific™ AUTO-READ™ locks in the stable reading on your screen, ready indicator alerts when readings are stable and timed reading gathers data in specific time intervals
- Up to five point pH calibration offers automatic recognition for USA/NIST™ and DIN buffers
- Calibration editing allows user to fix pH calibration errors without a complete recalibration.
- Selectable cell constant allows for use with 2- or 4-cell conductivity cells.
- Selectable reading reference temperatures of 5°, 10°, 15°, 20° or 25°C with linear, nonlinear, nLFu or EP curve options offer advanced accuracy in conductivity readings.
- User can choose practical salinity or natural sea water curves for salinity readings.
- Linear or ISO/EN 27888 curves for TDS are available.
- USB and RS232 ports and complimentary data analysis software allow user to easily transfer data and keep meter software up to date.
