Measure pH, ISE, conductivity, temperature and dissolved oxygen with this perfectly protable, waterproof (IP67 rated) meter with protective armor and built-in probe holders. Plain language screen prompts allow user to intuitively navigate the advanced features of this meter. Don't miss a reading - 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.
Calibrate pH at up to 5 points with automatic recognition for USA/NIST and DIN buffers.
No need to worry about DO probe compatability - the meter accepts and automatically recognizes Orion polarographic and RDO optical/luminescence-based probes. It is easy to get accurate DO results with automatic temperature, automatic/manual barometric pressure and automatic salinity compensation when used simultaneously with conductivity. Calibrate for DO using water-saturated air, air-saturated water, a Winkler titration or zero point calibration.
Selectable cell constant allows for use with 2 or 4 cell conductivity cells. For advanced accuracy in conductivity readings, selectable reading reference temperatures of 5, 10, 15, 20 to 25 degrees C with linear, non-linear, nLFu or EP curve options plus choice of practical salinity or natural sea water curves for salinity readings.
Whether you use ISE infrequently or have multiple samples every day - up to 5 point ISE calibration with advanced features such as timed end point, linear point-to-point, non-linear selectable auto-blank and low-concentration range stability.
Non-volatile memory holds up to 5,000 data points with time and date stamp. Easily transfer data and keep meter software up to date with the USB and RS-232 ports and complimentary data analysis software.
