Can E-1325M pH Electrode be use on any pH meter or controller? - Definitely, can work well with handheld meters, testers, or controllers. Re-use the meter portion indefinitely with this replaceable pH electrode. How does E-1325M works? 1. Allows you to connect 50 Ohm BNC socket directly into the input terminal of pH meter or pH controller or any pH device that has a BNC input terminal. 2. Once your new pH electrode probe is connected to the electrode input terminal, you will need to calibrate it using the supplied calibration (buffer) powder. 3. Has a longer body, an economical, and quickly provide highly accurate resultsit has a 50 Ohm BNC Type. : 1. 300cm extra long cable 2. 50 Ohm BNC type connector 3. Easy to Use 4. Easy to calibrate 5. Protective Carrying Case 6. Quality Assurance Due to different product batches, the appearance , which does not affect the use.

Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. Useful Electrode ! - Many users (those in clean water treatment, pool and spa water testing, chemical, laboratory and even some waste water applications), have their needs met with testers, meters or controllers that have replaceable pH electrodes. HIGH ACCURACY PH METER THAT WORKS EXACTLY AS IT SHOULD - If you own a fish tank, a pond or a swimming pool, grow Hydroponics, into beer brewing, wine making, gardening or just worried about the quality of the water that your family drink or the food they eat, you know the importance of a precise and portable pH meter with a resolution of 0.01, two decimal display and ATC. You will get spot-on readings of the pH levels of the tested solutions in no time and with no hassle, stress or color charts BNC Connector serves you right - This type of connector is universal in that it can be used on any pH meter that has the BNC probe input. A pH electrode is a crucial component in pH measurement systems, playing a pivotal role in determining the acidity or alkalinity of a solution. It is indispensable tools for pH measurement in various industries, including laboratory research, environmental monitoring, water treatment, food and beverage production, and pharmaceutical manufacturing. Their accurate and reliable performance makes them essential for maintaining optimal pH levels in diverse applications.
