CX-461 Handheld Multi-Parameter Meter w/o sensors

Key Features

• Large colour graphic touch screen. 
• Accurate measurements of  pH, ORP, conductivity, dissolved oxygen, atmospheric pressure and temperature.
• Suitable for field measurements as well as during accurate laboratory work.
• Waterproof housing (IP-66) enables working in difficult conditions.

In the pH and mV measurement function:

• pH & conductivity measurement circuits are isolated one from another.
• 1-5 point pH calibration (selectable)
• Automatic buffer detection and user set buffers
• Possibility to store characteristics of 3 pH electrodes
• Precise Redox potential measurement (accuracy 0.1mV).

In the conductivity measurement function:

• Full measuring range enables measurements in ultra pure water as well as in very salty solutions.
• 6 sub-ranges switched automatically.
• Calibration by entering the constant K in range 0.01÷19.999 cm-1 or in standard solution.
• Possibility to store constants K of up to 3 cells
• Wide range of a coefficient 0÷10 % / °C
• Selectable reference temperature correction.
• Automatic calculation of conductivity into salinity in NaCl or KCl
• TDS coefficient can be defined  in range 0.2 ÷ 1.0.
• Can measure and display atmospheric pressure

In the dissolved oxygen measurement function:

• Automatic calculation of atmospheric pressure influence on dissolved oxygen measurement value. 
• Automatic transfer of the salinity measured in the conductivity mode to the oxygen measurement mode 
• 1 or 2 point oxygen sensor calibration. 
• Wide measuring range

Other features:

• Internal clock with date.
• Internal datalogger with temperature, time and date stamping
• Non-volatile memory of the stored results and calibration data
• Continuous work time without charging up to 81 hours depending on the chosen function and set brightness of the screen.
• Connecting with a PC by RS-232 or USB output using an adapter (optional). 
• The meter meets the GLP requirements.
• 24 months of warranty for the meter
