INSTRUMENTS

Benchtop, precise, accurate measurements. The built-in microprocessor enables advanced functions, such as automatic calibration, automatic temperature compensation, self-diagnosis, auto power-off, and low-battery indicator, and improves the response time and accuracy of your measurements. The MAX Benchtop Conductivity/TDS/Salinity/Temperature meter feature a large LCD display that provides simultaneous Conductivity and temperature readings with a resolution of 0.1 µS and an accuracy of ± 2% Full scale. Conductivity probe with integrated temperature sensor. 5 points automatic calibration and extended range up to 150.0 mS. Product features 5 point automatic calibration Auto-Ranging feature for EC/TDS Automatic Temperature Compensation (ATC) for higher accuracy under fluctuating temperatures Conductivity/TDS/ probe with integrated temperature sensor Stability indicator TDS Conversion factor Hold Function momentarily freezes reading for easy viewing and recording Auto-Power Off saves battery power after non -use Self-Diagnostic with message codes for easy troubleshooting Large custom dual LCD provides optimal viewing Specifications: Conductivity Range                    Resolution               Accuracy 0.00 to 19.99 μS/cm                         0.01μS/cm                   ± (2%FS + 1 digit) 20.0 to 199.9 μS/cm                         0.1μS/cm 200 to 1999 μS/cm                           1μS/cm 2.00 to 19.99 mS/cm                        0.01mS/cm   Salinity Range 0 to 10ppt                                         0.01 ppt                          ± (2%FS + 1 digit) TDS Range 0.00 to 9.99ppm                            0.01ppm                         ± (2%FS + 1 digit) 10.0 to 99.9ppm                             0.1ppm 100 to 999ppm                               1ppm 1.00 to 10.00ppt                             0.01ppt   Resistivity Range: 0.0 to 100.0 MΩ                          0.1 MΩ                           ± (2%FS + 1 digit) Constant K:
