Knowing the pH of your reef tank, or the electrical conductivity of your RODI water is a necessity, and Hanna's HI98129 Combo Pen is the perfect all in one solution. The lightweight and portable pen can test pH, conductivity, or TDS (total dissolved solids) in a single pocket-sized device. The HI98129 can also read the temperature and all the readings are ATC (automatic temperature compensated) which means values will be more accurate.
The pH electrode can be changed, meaning that you will not have to throw away the HI98129 after the probe has exhausted. Almost all pH sensing devices will last about a year or so until the electrode needs to be replaced, and traditionally you would need to buy a whole new metering pen, now you do not have to replace the meter! Just replace the pH cartridge that houses the electrode, and the sturdy snap-in connector will hold the electrode in place until the next time you need to replace it.
