Myron L Chlorine Editorial Review

The Myron L PT4 Ultrapen Chlorine Tester is a tool that replaces the sensor entirely when the measurement solution is used up. It can last over a year before requiring calibration. The PT4 gives users the Free Chlorine Equivalent (FCE) number with Ph correction. The pen measures pH and ORP and calculates the free chlorine based on the results. However, it does not directly measure and report pH. In general, the product is well received by customers. A user mentioned that it was a reliable tool, and others noted that it was easy to use and provided accurate readings.
