Multiparameter pH/mV/ISE and EC/TDS/Salinity Benchtop Meter

Rugged and highly accurate multiparameter benchtop meter

HN/002550 - Multiparameter pH/mV/ISE and EC/TDS/Salinity Benchtop Meter

The HN/002550 is a rugged and highly accurate multiparameter benchtop meter.

Offering two input channels, this meter is able to measure up to seven parameters including pH, ORP, ISE, EC, TDS, salinity, and temperature.

The meter comes with  HN/01131B glass pH electrode, HN/076310 four-ring conductivity probe, and a temperature probe to allow for automatic temperature compensation.

The HN/002550 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.

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

Details

The HN/002550 is a rugged and highly accurate multiparameter benchtop meter that measures pH/ORP/ISE, EC/TDS/Salinity, and temperature with a clear LCD display, data logging capability, and USB port for computer connectivity.

The HN/002550 is a dual channel meter that allows for measurement of pH, ORP, and ISE on one channel and EC, TDS, and salinity, on the other.

Readings for pH and EC can be manually or automatically compensated for temperature variations with the separate HN/007662 temperature probe or from the built-in temperature sensor of the conductivity probe on channel two.

As a pH meter, the HN/002550 can be calibrated up to five points with a choice of seven standard buffers or two custom buffers.

As an EC/TDS/Salinity meter, the HN/002550 can be calibrated at one point for offset and at one point for slope with a choice of six conductivity standards.

The % NaCl is calibrated to a single point at 100% with the optional HI7037 salinity standard.

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.

Features at-a-glance

HN/01131B pH Electrode

• The HN/002550  is supplied with the HN/01131B 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 HN/01131B to be used in a wide variety of application from samples with metals and Tris buffer to samples at elevated temperatures

HN/076310 Conductivity Probe

• The HN/076310 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

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

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 

• In the EC and TDS measurement modes, the HN/002550 automatically chooses the optimum measurement scale based on the sample solution to maintain the highest possible accuracy

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, slope, cell constant, and cell factor can be accessed at any time by pressing the dedicated GLP button

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)
