Abstract: The present invention provides a method and apparatus for instrumental analysis in remote locations. In one embodiment, the present invention provides a method of controlling cathodic protection being applied to a metal structure having a surface disposed in an electrolytic environment comprising electrically connecting a metal coupon to the surface of the metal structure, positioning the metal coupon at a predetermined position relative to the surface of the metal structure and within the electrolytic environment, applying a cathodic protection agent to the surface of the metal structure to effect cathodic protection of the surface of the metal structure, measuring a cathodic protection indication proximate to the metal coupon, comparing the cathodic protection indication with a predetermined value, and adjusting the cathodic protection agent being applied to the surface of the metal structure in response to the comparison.

Abstract: A mixer valve assembly is provided comprising a pressure balancer cartridge including radially extending lugs, a mixer valve in fluid communication with, and supported by the pressure balancer cartridge, and a housing fitted over the pressure balancer cartridge and the mixer valve, the housing including notches for coupling to the lugs. The mixer valve can be used as part of a water faucet assembly. In this respect, a water faucet assembly is also provided comprising a faucet body including a sleeve, a base provided at one end of the sleeve, and fluid passages formed in the base, and a mixer valve assembly, disposed within the faucet body, including a pressure balancer cartridge including radially extending lugs, a mixer valve in fluid communication with, and supported by the pressure balancer cartridge, and a housing fitted over the pressure balancer cartridge and the mixer valve, the housing including notches for coupling to the lugs.
