1Testing Tool: This electrode is a plastic shell non fillable composite electrode. It is a measuring element for a pH meter, which measures the hydrogen ion activity (PH value) in an aqueous solution. 2Widely Use: It is widely used for testing the chemical industry, pharmaceutical industry, dye industry and research industry, aquariums, hydroponics, laboratories PH value. 3Using Purpose: The pH meter consists of a special measuring probe (glass electrode) connected to the body to measure and display pH readings. 4BNC Connector Using Range: Suitable for most pH meters and controllers with BNC connectors, very convenient for your use and test sensitive. 5Easy to use: The PH probe is small in size and light in weight, which is convenient to carry and use. The PH trial range is 0.00-14.00PH, and the working temperature is 0-60. Item Type:PH electrode Material: Plastic Weight: Approx. 80g or 2.8oz BNC Connector: Suitable for most PH and controller BNC connectors PH Trial Range: 0.00-14.00PH Response Time: 1min Working Temperature: 0-60 Cable Length: Approx. 70cm or 27.6in Equipotential Point: 70.5PH (25) 1 xPH Electrode 1 x Storage Box Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
