This is not a biological evidence record. It can govern a measurement, regulation, professional practice, maintained reference or named product instruction. It cannot silently become a Neocaridina experiment or animal-outcome threshold.
Permitted use
Conductivity measurement, temperature compensation and TDS-conversion-factor context for the named instrument.
Boundary
A conversion factor does not reveal dissolved composition, hardness or a Neocaridina optimum.
