HI2550-01

Description

The HI2550 is a rugged and highly accurate multiparameter benchtop meter. Offering two input channels, this meter is able to measure up to 6 parameters including pH, ORP, EC, TDS, salinity, and temperature. The meter comes with Hanna’s HI1131B glass pH electrode, HI76310 four-ring conductivity probe, and a temperature probe to allow for automatic temperature compensation. The HI2550 offers many features including five-point pH calibration, auto ranging EC and TDS measurements, data logging, comprehensive GLP data, and PC connectivity via USB to provide users with a simple way to organize and manage their data.

•  Autoranging EC and TDS measurements
•  Automatic Temperature Compensation
•  Two Independent Channels

Features at-a-glance
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.

  Automatic Calibration
•  The pH channel offers up to five-point pH calibration with seven standard buffers and up to two custom buffers.
•  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.

  Autoranging
•  The In the EC and TDS measurement modes, the HI2550 automatically chooses the optimum measurement scale based on the sample solution to maintain the highest possible accuracy.

  Data Logging
•  The log-on-demand feature allows up to 200 data points to be recorded.
•  Up to 500 data points can be recorded when utilizing interval logging, which allows the user to specify time intervals from 5 seconds to 180 minutes.

  Data Transfer
•  With a built-in logging function, measurements are stored in non-volatile memory, and can be transferred to a PC through the USB port using the optional HI92000 software and HI920013 USB cable (both sold separately).

  HI76310 Conductivity Probe
•  The HI76310 platinum, four-ring probe measures EC, TDS, and salinity.
•  The probe features a built-in temperature sensor and operates over a wide range from 0.00 μS/cm to 500.0 mS/cm (actual conductivity), 0.00 to 400.0 g/L (actual TDS), and 0.0 to 400.0% NaCl.

  HI1131B pH Electrode
•  The HI2550 is supplied with the HI1131B glass body, double junction, refillable pH electrode with an indicating sensor made of High Temperature (HT) glass.
•  The double junction and HT glass design allows the HI1131B to be used in a wide variety of application from samples with metals and Tris buffer to samples at elevated temperatures.

  GLP Data
•  The calibration data including date, time, standards used, offset, slope, cell constant, and cell factor can be accessed at any time by pressing the dedicated GLP button.

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