This continuous pH monitor is rugged in design and function. The meter displays both pH and temperature and is unaffected by electromagnetic fields from pumps located in reservoirs. It has a tested back lit LCD display and that is bright enough to easily see but not strong enough to cause problems with flowering plants. It has both, a temperature and pH electrode for superior accuracy and reliability. Calibration screws are located on the front for easy and reliable accuracy and it is powered by a 120 volt ac to dc transformer. Retail Price: $106.95
