Lab Benchtop pH Conductivity TDS Temperature Meter USB Interface !!! Liquid/Powder Not Included During The Shippning!!! Multiparameter pH/conductivity meter contains 12 options, the meter is suitable for measuring the pH, mV, conductivity and total dissolved solids (TDS). pH Mode: • Multiparameter pH/conductivity meter is equipped with a large backlit LCD display. • 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers. • Automatic electrode diagnosis shows the pH slope and offset. Conductivity/TDS Modes: • 1 to 5 points calibration with automatic recognition for conductivity standards. • Selectable cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS factor, linear and pure water compensation modes. Other Features: • Automatic temperature compensation ensures accurate readings over the entire range. • Auto-Read function senses and locks the measurement endpoint. • Calibration due alarm prompts user to calibrate the meter regularly. • Setup menu allows setting the number of calibration points, stability criteria, temperature unit, date and time, auto-power off, etc. • Reset function automatically resumes all settings back to the factory defaults. • Expanded memory stores or recalls up to 500 data sets. • USB communication interface for data transfer and timed interval readings.
