Abstract

A probe colorimeter has at least one light-gathering rod probe 13 held captive in a non-transparent block 12 with the lower end extending below said block and the upper end extending into a chamber 20 in the block. The block is mounted for sliding vertical movement on two spaced apart pillars 11 upstanding from the upper surface of a light box 10, and means being provided to move the block up or down on the pillars. The light box has a light source 23 positioned between the roots of the pillars. A photosensor 21 is mounted in chamber 20, in vertical optical alignment with the source. A tray or plate 33 having a solution-containing well 34 with a transparent base is positioned above the light box with the well base in registry above the light source and the block is lowered for the probe to dip into the solution. The embodiment of Fig. 4 has a plurality of probes 13 and the corresponding apparatus for measurements on a plurality of solutions 21 is preferably a photoresistor and the change of current due to absorption is detected by a balance circuit to feed a multiway switch or multiplexer. <IMAGE>
