1. An improved electronic wiring board having a nonconducting substrate, temperature sensor and at least one analyte sensor supported, in close relation, one to the other, on the same side of said substrate and a heater, also supported on the substrate, and located on another side of said substrate from the temperature sensor and analyte sensor to provide heat in response to temperature sensed by said temperature sensor to at least the region where said temperature sensor and said analyte sensor are positioned on said substrate to thereby control the temperature of said region of said board within a narrow distribution of temperatures, and connecting means supported on said substrate for connecting said board to an external electrical source.
