Environmental Express`s fast-response fermentation pH electrodes are made of a proprietary new formulation of low-impedance glass replaces all other formulas — allows you to streamlined inventories and eliminate wasted time trying to select the best electrode for your application. Use in low-ionic strength solutions, high pH testings where sodium error could be a problem, and at high temperatures up to 266°F (130°C). pH is registered in less than 20 seconds, with a typically accuracy of 0.02 pH units (meter dependant).
Chemical-resistant Ryton ''PPS'' PG13.5 threaded pressure fitting, PTFE spacer, and silicone o-ring ensure a leakproof connection to your assembly.
All electrodes feature double-junction reference for maximum lifespan.
