As for the testing equipment is more,
(a) aseptic room or ultra-clean bench;
(b) sterilizer;
(c) microbial incubator;
(d) biomicrographic microscope;
(e) turbidimeter;
(f) measuring instruments;
(vii) acidimeter (). For bottled drinking water);
(h) conductivity meter (for bottles, barrels of pure water);
(ix) analytical balance (0.1mg) (platinum and cobalt colorimetry turbidity measurements need).
Of course, the average barrel of pure water production plant does not need so much testing equipment.
