Abstract:
A temperature sensitive feedback mechanism may be mounted or positioned on a heat conducting diluent conduit. The temperature sensitive feedback mechanism provides visually readable feedback regarding the temperature of the diluent to help ensure that the temperature of the diluent delivered to a chemical product dispenser satisfies a target temperature or falls within a target temperature range. The temperature sensitive feedback mechanism may include one or more temperature sensitive elements that change color in response to a change in surface temperature of diluent conduit. A user may view the visually readable temperature feedback and manually adjust the temperature of the diluent if necessary until the desired diluent temperature is reached.
