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.
The photometer employs the methods defined in the American Standard Methods for water analysis.
This instruction manual outlines the functions and operations of the photometric instrument only.
Instructions specific to each test are included with the reagent packs as purchased from Trace2o Ltd.
The instrument has been designed and optimized to work solely with Trace2o reagents. A complete
list of available parameters is included in Appendix 1.0
The instrument has been designed for use in an outdoor environment and is rugged and waterproof
however the optical system should also be checked for cleanliness before use particularly
condensation build up in the cell chamber.

2.0 Operation
2.1.1 Set up
Before working with the photometer it may be necessary to insert the batteries if supplied
separately. See chapter 2.1.2 Saving data –Important information, 2.1.3 Replacement of
batteries.
Before using the photometer perform the following settings in the Mode-Menu:
• MODE 10: select language
• MODE 12: set date and time
• MODE 34: perform “Delete data“
• MODE 69: perform “User m. init” to initialise the userpolynomial system
See chapter 2.4 Photometer settings.
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.
2.1.3 Replacement of batteries
See chapter 2.1.2 "Saving data - important Information" before replacing batteries.
1. Switch the instrument off.
2. If necessary remove vial from the sample chamber.
3. Place the instrument upside down on a clean and even surface.
4. Unscrew the four screws (A) of the battery compartment cover (B).
5. Lift off battery compartment cover at the notch (C).
6. Remove old batteries (D).
7. Insert 4 new batteries ensuring the correct polarity!
8. Replace the battery compartment cover.
Check the seal ring (E) of the notch to make sure it is a tight fit. If the seal appears
stretched or damaged then a replacement should be obtained to ensure the waterproof
seal is maintained.
9. Tighten the screws carefully.

2.3.5 Changing chemical species
For some methods there is a possibility to change the chemical species of the test result.
If the test result is displayed press arrow key [ ] or [ ].
Example:

If the species of a test result is changed the displayed range is adjusted automatically. For an
already stored result it is not possible to change the chemical species. The last displayed chemical
species is kept by the instrument and will be displayed if this method is used the next time. If there
is the possibility to change the chemical species for a method it is described in the manual. The
arrows indicate the possible chemical species and are printed below the notes of the method:

Notes:
1. It is possible to interrupt the working countdown by pressing the [ ] key (application e.g.
serial analysis).
The “user countdown”is also available if the countdown is switched off.
2. If the countdown function is switched off, the operator is responsible for ensuring the
necessary reaction period.
Non-compliance with reaction periods leads to incorrect test results.
