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
