Leave this field blank Reveal Questions External ADCs, such as the ADS1115, come on PCBs with other resistors and capacitors, but no other ICs. Are these allowed? It says in the rules that the ORP probe must be participant built; can teams purchase electrodes online as components of a probe and then use those to construct the probe itself? Regarding the digital display of the salt concentration, may the display be more precise than the nearest unit value (e.g., 0.1 ppm, 0.01 ppm, etc.)? Perhaps the rule should be TO AT LEAST the nearest unit value. The language describing the device has been updated since Detector Building last ran Salt Concentration Sensing, changing from conductivity sensor to ORP probe. Is it required that the device be an ORP probe, or can it still use any means (within ... The wording here has me a bit confused, are we allowed to purchase a salt bridge and electrode in order to combine them into an ORP sensor? Or do we have also have to construct a salt bridge and electrode from basic materials? Will a salt bridge containing metal be considered a salt bridge? Would a thermistor be considered a fundamental component and could we measure temperature to supplement our ORP readings as they could change with temperature? ‹ Are equilibrium pressures testable within the context of equilibrium calculations since it says equilibrium concentrations? External ADCs, such as the ADS1115, come on PCBs with other resistors and capacitors, but no other ICs. Are these allowed? ›
