• 1 bottle of 35ml of reagent A
• 1 bottle of 8g of reagent B
• 1 bottle of 35ml of reagent C
• 1 measuring spoon n° 2
• 2 plastic test tubes of 20ml with stopper
• 2 test tubes of 16mm optical glass with stopper
• 1 syringe of 5ml
• Instructions (English)

• The indophenol method, relatively modern, offers excellent sensitivity. The classic Nessler method, which is less sensitive, is preferred in the case of possible interference.
• The SPECTRATEST HYDROCHECK kits (which can be purchased directly) require the use of a photometer or spectrophotometer to perform many precise analyzes at a very low cost per analysis. HYDROCHECK MONOTEST kits are preferred because of their greater convenience and safety of use. The cost per analysis of MONOTEST kits is higher, but the analysis is very simple because the samples to be analyzed are introduced into optical glass tubes containing the pre-dosed reagents that can be used directly in the appropriate photometers. MONOTEST kits are recommended when there are few analyses to be performed. As for the photometer, it is preferable to use a spectrophotometer such as the Hydrocheck or Spectronic Genesys, since filter photometers give less reliable and precise results, as well as always requiring the construction of a calibration curve.
