Autoranging Benchtop EC/TDS/Salinity Meter with ATC - HI2300

SKU: HI2300-01

Ships within 1-2 Business Days

The HI2300 is an auto ranging EC/TDS/Salinity and temperature benchtop meter. The meter utilizes a four-ring potentiometric conductivity probe with platinum sensors to offer versatility over typical amperometric designs. By utilizing the four-ring probe, it is possible to measure very low or very high conductivity levels without having to change probes. The HI2300 also offers three options for temperature compensation, as well as an adjustable temperature coefficient (β) and TDS factor. GLP capabilities and PC connectivity via USB provide users with a simple way to organize and manage their data.

  • Autoranging EC and TDS measurements
  • Adjustable Cell Constant
  • Automatic Temperature Compensation

The HI2300 is a durable benchtop EC/TDS/Salinity and temperature meter that features a four-ring potentiometric probe, one-point calibration, and a USB port for computer connectivity. This meter is auto ranging to choose the appropriate conductivity and total dissolved solids (TDS) range, and can easily be switched to salinity mode to measure from 0.0 to 400.0% NaCl.

Features at-a-glance

Autoranging - In the EC and TDS measurement modes, the HI2300 automatically chooses the optimum measurement scale based on the sample solution to maintain the highest possible accuracy.

Automatic Calibration - EC and TDS are automatically calibrated at one point with a choice of six pre-programmed standards. Salinity is calibrated at one point using the HI7037 100% NaCl standard solution.

Four-ring EC Probe - The HI2300 meter is supplied with the HI76310 platinum, four-ring EC/TDS probe with a built-in temperature sensor that operates over a wide range from 0.00 μS/cm to 500.0 mS/cm*.

Temperature CompensationTemperature can be compensated for automatically (ATC) or manually (MTC) from -20.0 to 120.0°C, or it can be disabled for actual conductivity or TDS measurements. The temperature correction coefficient, also referred to as β, is adjustable from 0.00 to 6.00 %/°C.

Adjustable TDS Factor - The factor that relates conductivity to total dissolved solids is based on the type of sample being measured. For users to get an accurate determination of TDS based on their unique solution, the TDS factor is adjustable from 0.40 to 0.80.

GLP Data The calibration data including date, time, standards used, offset and cell constant can be accessed at any time along with the current measurement by selecting the Good Laboratory Practice (GLP) display option.

Data Logging - The log-on-demand feature allows up to 500 data points to be recorded. The data can be recalled on the meter display with a simple press of the “RCL” button.

Data Transfer Data can be exported to a computer for data review and storage with a USB cable and HI92000 software (both sold separately).
