Cole-Parmer High-pH Double-Junction pH Electrode, 10-ft Cable

Standard models are available with a 10- or 25-ft cable with BNC connections. Preamplified models put an end to problems associated with high impedance signals-ideal for environments with high electrical noise or high humidity. Order replacement batteries for preamplified models separately. Connect these electrodes to standard pH or ORP meters to send a signal up to 1000 ft without an external power supply. Order industrial housings seperately. High-pH, double-junction electrodes are well suited for pH levels above 13 or high sodium ion concentrations. Double-junction reference protects against contamination from heavy metals, organics, and sulfides. Maximum pressure is 150 psi at 25°>C. Note: 100Ω RTD ATC elements are platinum and conform to DIN curve 43760. ATC connector is miniature audio plug. Connector for the 1 kΩ RTD and the 3 kΩ Balco ATC elements is a spade lug. Connector for 100 kΩ thermistor ATC elements is a standard 1/4" phone plug. Use for many applications in a variety of housings Preamplified version allows for long cable runs
