pH meters-ionomers “Expert-001” is a model range of pH meters based on liquid analyzers “Expert-001”. Possibility of expansion for new tasks due to additional configuration with ion-selective electrodes.

Appointment in the basic configuration: measurement of pH, mV, T °C.

pH measurement error complete with pH electrode:

  • 0.03 pH – for the model pH-meter-(ionomer) “Expert-001-1(0.1)”
  • 0.05рН – for models of pH meters-(ionomers) “Expert-001-3(0.1)” and “Expert-001-3(0.4)”

When equipped with ion-selective electrodes, electrodes Eh – measurement of activity, mass and molar concentration of ions, redox potential.

Objects of analysis:

  • sewage, drinking, natural waters.
  • aqueous solutions of samples of plant, food products, soils, etc.

Distinctive features of pH meters-(ionomers) “Expert-001”:

  • compatible with any pH electrode (BNC or K80.7 connector)
  • possibility of independent input of isopotential point
  • automatic and manual compensation for pH measurement
  • number of calibration points for buffer solutions – from 2 to 5
  • calibration according to any pH buffer solutions
  • automatic calculation of measurement results in mV, pX, M, mg/l
  • compatibility with any ion-selective electrodes (optional)
  • storage of calibrations for 32 ions in memory
  • constants for 32 ions in the device memory
  • information output to a portable thermal printer (receipt tape, thermal label)
  • PC connection (software included)
  • powerful battery for battery life
  • bright backlit display
  • power supply of the magnetic stirrer from the device in the field
  • traffic shock resistance
  • low noise level during operation
  • use as a high-resistance millivoltmeter for potentiometric measurements: measurements by the method of standard additions, titration, COD measurements, etc. according to the corresponding MVI.
  • warranty – 24 months
