Abstract :
Demineralize water is the main ingredient as boiler feed water. To
maintain the quality of the content on demineralize especially water content
results in a pH that should not be too low because it causes corrosion on the
boiler it is necessary to check in the laboratory. However, the results of the checks
demineralize water by laboratory unit for too long, so when demineralize water
contaminated by liquid low pH resulting in damage to the boiler. In this study,
demineralize water monitoring system using SMS to monitor content results
demineralize through messages sent to mobile phones. From the results of testing
this device can transmit the content of pH and temperature through the
demineralize water using SMS with the timely and accurate. Demineralize water
monitoring system is able to send SMS to destination mobile phone danger when
demineralize experiencing low pH water.
