Experience an easier way of water testing and monitoring with the use of the HM Digital pH/ORP Electrodes Storage Solution from Pet Store. In a 60-cc bottle, this storage is formulated with Potassium Chloride (KCl) that is designed specifically to store the HM Digital`s PH-200 and ORP-200. This storage place for your pH sensors and ORP electrodes keeps quality of the sensors intact.

The HM Digital pH/ORP Electrodes Storage Solution is easy to use. Simply put the sensors in the storage solution. Check regularly to ensure the right amount of solution is in the cap. If not, simply add the right volume of OP-STOR solution. The bottle is equipped with an easy twist off cap that also serves as an eyedropper cap.

The HM Digital pH/ORP Electrodes Storage Solution has many uses. It can be used for handheld testers such as the Basic TDS TesterTDS-EZ , Conductivity Meter with CaseTDS-4, and Pocket-Size TesterTDS-4TM and Digital Thermometers. It can also be used for in line monitors such as SM-1: Single Line TDS Monitor, and PM-2: External Purity Monitor. It is also used in controllers like PS-100: TDS Controller, PC-100: Conductivity Controller, and PSC-154: TDS/EC Controller with 4-20mA Output. It is definitely a unique way of keeping your aquarium water free from any pH and ORP imbalances.
