Everything under control
stakpure digital and analogue conductivity monitoring.
stakpure DC 400. Digital conductivity meter.
Developed for online measurement of pure and ultrapure water downstream of ionexchange cartridges and for monitoring ring-main systems. High-precision conductivity meter ensuring exact measurement of temperature and conductivity for constantly monitoring quality. Digital display guarantees to show readings even at the lowest end of the conductivity measurement range.
Comes complete with connecting cable, plug-type power supply unit, set of two 1.5 m hoses and measuring cell.
Large graphic display
2-colour, back-lit graphic digital display indicating conductivity in μS/cm or in MΩcm and temperature in °C. Background illumination changes from green to red to signal a fault and show plaintext message.
LED indicators
Show red/green to signalise when limit values are exceeded for temperature and conductivity.
Limiting values
Infinite adjustment of limiting values for temperature and conductivity.
Interfaces
Direct connection of peripheral equipment at potential-free contact. Optional interface RS-232 for documentation and connecting a printer.
High-precision measurement
Automatic calibration before each measurement with integrated reference resistor, temperature measured by platinum temperature sensor.
Voltage selection
Automatic voltage selection for international use.
