What LibertyCES's vendor documentation shows

Two real engineering constraints to publish alongside the catalog. First, minimum conductivity: the 2551 and 2552 both require 20 µS/cm, so they will not work on deionized or ultrapure water — that is where the 2100 turbine, 2507 paddlewheel or a clamp-on ultrasonic takes over. Second, Signet's recurring tip: for liquids containing ferrous particles use magmeters, not paddlewheel or turbine sensors, and for multi-material systems always reference the max temperature/pressure spec to the lowest-rated component. The 2536 PVC-body variant's explicit 12.5% sodium hypochlorite rating is an independent instrumentation-category confirmation of the project's existing hypochlorite guidance. Icon's Kalrez FFKM option is the documented escalation path when Viton is the limiting component.
