PMT140, measures the electrochemical potential resulted from pH, ORP (oxidation reduction potential) and ISE (ion-selective electrode) probes. Also measuring the actual temperature, temperature-compensation is done automatically. Whether needing redundancy for critical measurements or simultaneous monitoring of two separate processes, PMT140 offers two independent measurement channels. Each channel is fully isolated from the other, ensuring reliable and accurate readings without interference. It transmits mV, pH and ORP through two different 4-20 mA current output channels. It has optionally IO-Link and wireless communication interface for direct access to process, configuration and diagnostic data.
