Product Description

The SpectroDirect is specifically designed for in-depth water testing. It allows you to measure 46 parameters at different wavelengths. After the initial cost, the cost-per-test is relatively low based on the proven range of Lovibond® tube tests, tablet, liquid or powder reagents.

Applications:

  • Waste water
  • Drinking water
  • Industrial process water
  • Scientific & research laboratories
  • Governmental and private laboratories

Advantages:

  • Single-beam spectrophotometer – high accuracy
  • Wavelength range from 330 – 900 nm
  • Computerised RS232 interface with large illuminated graphic display
  • Touch-sensitive film keypad
  • Use round vials and rectangular cells of different sizes without an adapter
  • The only maintenance that is required is a lamp replacement. Fast, easy lamp change requires no tools as it is easily accessible
  • 35 user specific methods
  • New methods and software updates available free of charge at www.tintometer.com
  • Choice of language – German, French, Italian, Spanish or Portuguese
  • N.I.S.T. Traceability – can be calibrated using a Secondary Standard Filter Set which is N.I.S.T. traceable. Furthermore the instrument may be calibrated for each method in a “user calibration mode” with N.I.S.T. traceable standards.

Functions:

  • Pre-programmed Lovibond® methods – 46 parameters. The user chooses the desired method either from the method list in alphabetical order or by entering a numerical code. If desired, additional information like the required vial, the reagent type and the measuring range can be displayed using the functional keys. The date and time are shown in the display by pressing the “clock key”. The SpectroDirect automatically selects the correct wavelength.
Zero Calibration is performed with the water sample by pressing the ZERO key.A characteristic coloration develops when you add the indicator to the water sample. Press the enter key to initiate the measurement (which starts either immediately or after the time required for colour development).
  • Data – There is an RS-232 interface for connection with a 9-pin D-Sub connector for connection of a PC or a printer with serial interface.
Every result is printed with date, time, reg.no., code no., measuring range and method number. You can store the results in a memory with 1000 data sets.
  • User Prompt – The user prompt is a convenient and easy to understand feature that guides the user step-by-step all the way through to the test result.
  • Countdown Function – With some methods, there is a waiting period for a colour reaction – this time interval is shown and an alarm rings during the last 10 seconds. This function can also be turned off for a series of samples.
  • Differentiation of results – Allows for differentiated tests for certain methods, Chlorine can be differentiated into free, combined and total Chlorine.
  • Functions – you can program your own applications, too – eg. create a user-defined method for a routine check.
  • Spectral data – A wavelength scan is performed over the user-defined interval between 330 and 900 nm. The display shows the graph of the spectrum; if the user presses a key, the display also shows a data list with the corresponding maximum and minimum absorption levels. This allows you to create more parameters and have more flexibility.
  • Absorption / Transmission – You can carry out measurement of standards with different concentrations using the user-selected wavelength in order to obtain the data pairs required for a polynomial. Result output is in Abs and % Transmission.
  • Polynomials – With the help of an external mathematical program, the corresponding polynomial is created from data pairs (concentration / absorption). A known polynomial may also be used. 10 order polynomials (y = A + Bx + Cx² + Dx³ + EX4 + FX5) can be stored together with user-specific parameters such as wave-length, measuring range, unit and number of decimals (up to three).
  • Concentration – This function can be used to measure 2 to 8 known standards. On the basis of the concentrations / absorption pairs obtained, the photometer will calculate a linear interpolation between the measured points. Up to 5 methods can be stored for further sample measurements.
