A portable photoanalytical device takes a reflectance reading from a reagent test strip, compares the reading to an internal standard, and translates the reading to a concentration value using constant values stored within a RAM chip. The constant values are preprogrammed for a particular lot of reagent test strips. A battery maintains the information stored in the RAM. The control values are init...

An electro-magnetic locking system includes a digitally derived encoder transmitter or electronic key (110) and a decoder receiver or electronic lock. The electronic key (110) is coupled to a pulse oscillator unit (112) whilst in turn is connected to an inductive load circuit (113). A series of pulses are radiated by the load circuit (113) in accordance with the data rate and data code as set by t...

A method for determining the presence of an analyte in a fluid is described along with an apparatus specifically designed to carry out the method. The method involves taking a reflectance reading from one surface (15) of an inert porous matrix (11) impregnated with a reagent that will interact with the analyte to produce a light-absorbing reaction product when the fluid being analysed is applied t...
