1.0 Introduction The HT1000 is part of the HydroTest range of instruments based on optical measurement technology for the analysis of a range of chemical parameters in aqueous samples. The HT1000 is a photometric analyser using 6 indivdual selective wavelengths to measure the colour change produced by a reagent when reacted with the analyte of interest.
2.1.2 Saving data – Important Information During replacement of the battery the data in the HT1000 is saved for 2 minutes. If the change time exceeds 2 minutes all stored data and settings are lost. It is recommended to have the replacement batteries to hand to expediate fitment.
