1. A luminometer assembly for use with a single use food product or surface test sample holder, said assembly comprising:
a. a handheld portable luminometer having
i. a sample port accepting said single use food product or surface test sample holder into a testing position,
ii. a photomultiplier assembly with at least one photomultiplier tube, and
iii. a distal base; and
b. a device having a microcontroller circuit communicating with a host device thereby acting as a graphical user interface presenting a food product or surface test result from said single use food product or surface test sample holder, and
wherein said photomultiplier assembly having a photomultiplier tube photon counter with an associated signal conditions circuit coupled to said microcontroller circuit thereby coupling a storage device to relay to said host device.
