PURPOSE:To achieve readiness, convenience, objectiveness, accuracy and labor- saving, by testing continuously and automatically water from sampling to measuring. CONSTITUTION:Test water sampled at a water-sampling section 1 is diluted and controlled by a continuous diluting and controlling device 2a at an automatic water-controlling section 2. Consequently, the water controlled at the controlling section 2, is seeded to a culture fluid in a fermentation tube in an automatic culture section 3, and cultured there at an appropriate temperature for a prescribed time. The cultured water is sampled at a automatic measuring and recording section 4, and determined by a turbidimeter or a spectrophotometer, then the observed value is displayed and recorded. The observed value measured at the section 4 is reserved on a memory of a diluting amount indicating section 6 and the diluting amount of water is computed on the basis of the reserved data. Each section is controlled automatically by a automatic process controller 7 with a suitable condition corresponding to a kind of bacteria by setting optionally condition for a measuring interval, culture time and etc. |
