The Orion 930101 liquid membrane pH electrode measures the pH of acid solutions, quickly, simply, accurately and economically. Unlike glass pH electrodes, corrosive solutions containing varying amounts of HF do not affect electrode performance or electrode lifetime. The Orion 930101 liquid membrane pH electrode measures the pH of acid solutions, quickly, simply, accurately and economically. Unlike glass pH electrodes, corrosive solutions containing varying amounts of HF do not affect electrode performance or electrode lifetime. The Orion 930101 electrode can be connected to any standard pH meter, but must be used with a plastic body reference electrode. NBS pH buffer solutions are recommended for standardization, but dilute acid standards (e.g., HCl) may be substituted, if desired. To ensure accurate results, all measurements must be taken at room temperature. Recommended Use: For pH determinations in hydrofluoric or other acid fluorides. Use with Orion 93 Series Electrode body and Orion 900200 Reference Electrode. Module only, requires separate 93 Series electrode body.
