Conductivity meter HANNA HI2300-02 (laboratory)
The Hanna HI-2300 measures conductivity, TDS (total dissolved solids), NaCl percentage and temperature. If necessary, the meter can be connected to a computer using the RS232 port, and additional Hanna software allows you to export data and print it. Featuring automatic conductivity and total dissolved solids (TDS) ranges, this instrument can be easily switched to salinity measurements ranging from 0.0 to 400.0% NaCl (seawater salinity). Peculiarities. Automatic Range Selection - For conductivity and TDS measurement modes, based on the solution sample being measured, the HI2300 automatically selects the optimal measurement range to ensure the highest possible accuracy. Automatic Calibration - EC and TDS ranges are automatically calibrated at one point with a choice of six pre-programmed standards. Four-electrode sensor - The HI2300 is equipped with a four-electrode potentiometric conductivity sensor HI76310 with a built-in temperature sensor and platinum sensing elements, which operates over a wide range from 0.00 µS/cm to 500.0 mS/cm *. Temperature compensation - temperature compensation can be either automatic (ATS) or manual (MTC) in the range from -20.0 to 120.0 °C. In addition, it can be disabled for actual conductivity or TDS measurements. The temperature compensation coefficient, also known as β, is adjustable from 0.00 to 6.00%/°C. Adjustable TDS Conversion Factor - The conversion factor from conductivity readings to total dissolved solids depends on the type of sample being measured. To obtain accurate TDS values in unique custom solutions, the TDS conversion factor is adjustable from 0.40 to 0.80. GLP Data - Along with conductivity measurements, calibration information, including date, time, standards used, offset values, and cell constants, can be displayed on the instrument at any time by selecting the Good Laboratory Practices (GLP) display option. Recording information - The on-demand event log function allows you to save up to 500 measurement results. Saved results can be displayed on the device screen by simply pressing the "RCL" button. Data Transfer - Measurement results can be sent to a PC for analysis and storage using a USB cable and HI92000 software (sold separately). Manba: https://www.nv-lab.ru/catalog_info.php?ID=3938
