Extech pH Meters EC500 Editorial Review
The Extech EC500 Waterproof ExStik II pH/Conductivity Meter seems to have mixed reception among customers. On one hand, some users find it to be a convenient and effective tool. They praise its easy calibration process, which involves using known lab grade pH calibration standards. They also appreciate the inclusion of a sponge in the cap and a sample cup for easy measurement. However, other customers express disappointment with the meter. They report that the calibration process becomes problematic over time, with the unit failing to calibrate for pH or conductivity. The readings also become inaccurate, even with attempts to troubleshoot and change the probe, solutions, and batteries. Some users claim that the meter stopped functioning correctly after only a couple of months of use, which they find unacceptable for a professional-grade instrument. Overall, it seems that the Extech EC500 Waterproof ExStik II pH/Conductivity Meter may not be suitable for casual users, as it requires ordering calibration liquid and involves a process to calibrate it. For those willing to put in the extra work, it can be a decent option. However, those planning to use the meter in a professional capacity might be better off investing in a more reliable and long-lasting option, such as a YSI meter. It is also worth noting that the manufacturer offers a decent warranty for the product.
