6685-99-525-0084 6685995250084 995250084 is an indicator which indicates the pressure of a gas or liquid in a given system.

6685-99-523-0084 6685995230084 995230084 is an instrument designed to measure air, gas, fluid, and vapor pressure by means of an internal pressure sensitive element (bellows, bourdon tube, transducer/transmitter and the like) which transmits energy, by direct linkage, to the indicating pointer of a scale or a digital display, calibrated in units of pressure.it may include a temperature equivalent scale.for items that do not have an internal pressure sensitive element see indicator, pressure.
