Description:1. A single cylinder of the pH electrode allows the BNC socket to be connected directly to the input terminal of a pH meter or pH controller or any pH device that has a BNC input terminal. The cable is long. This gives you the flexibility to measure your solution in a container with the device. 2. Only your new pH electrode probe is connected to the electrode input terminal, you will need to calibrate it using the provided calibration (buffer) solutions. This pH electrode is economical, quick response and is equipped with a protective cover to ensure the safety of the bulb. 3. It can be used for general water applications, such as drinking, domestic and rainwater, swimming pools, aquarium, green houses, and its compatible with handheld shower meters or controllers. Features: Easy to monitor accurately and pH values can be reached within seconds Replaceable pH electrodes is easy to calibrate Comes with fluid calibration It is very reliable, stable and portable The operation is simple and convenient It comes with a storage solution, can be kept moist to maximize electrode performance and extends electrode life Specification: Measuring Range: 0.00 - 14.00PH Resolution: 0.01PH , You can mention them: ± 0.01PH Operating Temperature: 0°C - 50°C Automatic Temperature Compensation (ATC): 0°C - 50°C Connection: Long cable with BNC socket Dimensions: 150mm long x diameter 12mm (without cap) Package Included:1 x BNC Type pH Electrode
