Page 5: Introduction
We advise to read the Quickstart-card carefully and act according to the instructions to ensure that the SENTRON TITAN system will work enjoyably for a long time. This manual can be of help when further details on features are required. -
Page 6: Layout Of The Meter
Manual TITAN 1.4. Layout of the meter 1.4.1. Keypad The ‘controls’ of the SENTRON pH meter are condensed to only six keys located on the keypad. The names ‘Power’, ‘Enter’ and ‘Arrow’ keys (‘Left’, ‘Right’, ‘Up’ and ‘Down’) will be used consistently throughout this manual. -
Page 7: Display
Manual TITAN 1.4.2. Display The TITAN’s display is a graphics Liquid Crystal Display (LCD). The pH value can be shown in 1 or 2 decimal resolution and temperature can be shown or be omitted. In chapter 3 these settings are explained in detail. - Page 8 SENTRON Europe BV Manual TITAN These smaller digits represent the actual temperature in C/ºF, see paragraph 7.3.1. Battery status indication When the remaining operational time is less than approximately 5 hours, a “low” indication will appear. When charging the battery, two alternating “+” symbols are shown on the right hand side of the battery symbol.

Page 9: Connections
Physically different connections guarantee that it is impossible to fit connectors to the wrong receptacle. Connectors are placed on the backside of the TITAN meter as shown in figure 3. Figure 3: Connectors available on TITAN From left to right, following connectors are available: Probe connector. -
Page 10: Help-Function
SENTRON Europe BV Manual TITAN HELP-Function The TITAN meter is equipped with an elaborate on-board help function, designed to provide to-the-point assistance. The HELP function presents a situation dependant overview of the meter’s functionality which will in most cases be sufficient for the user to continue operation. -
Page 11: Calibration
Manual TITAN Calibration To obtain reliable readings from the TITAN system it must first be calibrated, using correct buffers, for maximum accuracy at the same temperature as the sample will The TITAN has four built-in tables of 5 buffers versus temperature. When performing a calibration, the bufferset chosen is shown on the display. -
Page 12: 1-Point Calibration
SENTRON Europe BV Manual TITAN Slope values can be interpreted as follows: Slope % Interpretation 98.0 – 105.0 % Probe gives maximum performance 94.0 – 97.9 % Probe functions fine. Some maintenance, cleaning with water, toothbrush, and a mild detergent as described in the Probe Insert can bring it up to maximum performance. -
Page 13: 2- Or 3- Point Calibration
SENTRON Europe BV Manual TITAN The text on the status text line will change to “Stabilizing” and the pH value is blinking until a stable signal is reached. The 1-point calibration is now complete, and the meter automatically returns to the Main menu. -
Page 14: Autoread: Stability Function
8 seconds to confirm stability; Hence, the measurement value will blink at least 8 seconds. SENTRON systems continuously monitor the sample’s pH value, i.e. the stable value is not fixed on the display, and when the sample’s pH changes, the value shown on the display will change accordingly. -
Page 15: Measurement Data Handling
SENTRON Europe BV Manual TITAN Measurement data handling The TITAN can store 300 Measurement Data Sets, including date and time. These Measurement Data Sets can be recalled on the display for future reference. 6.1. Sample identification In order to simplify data recognition, a 9-character identification is allocated to the sample. - Page 16 SENTRON Europe BV Manual TITAN The last measurement stored is shown on the display as follows: pH 12.34 - 123.4 °C SAMPLE-000 Recall Next Help Prev Selct Back Figure 4: Recall menu The probe status symbol is not shown in this menu. The text “Recall” is blinking on the status text line.

Page 17: Data Deletion
6.4.2. Delete data The TITAN has a memory that allows storage of 300 Measurement Data Sets. In the Store menu, the amount of free memory slots is continuously indicated in the status text line as “xxx free”. -
Page 18: Additional System Configuration
7.1. Bias option In some cases it is possible that there is a difference in measurement results between a Sentron pH measuring system and a classic glass electrode system. This difference can be eliminated by entering a “bias”. Use the arrow keys to go to the menu option “bias”. This is a submenu of option “config”. -
Page 19: Display Contrast
Especially with battery powered meter operation, energy conservation is important to optimize the operational time of the meter. The TITAN can automatically switch itself off after a pre-defined period of inactivity. In the Main menu, go to “Config” and press ‘Enter’. -

7.3.4. Calibration buffers Following sections list the buffersets built into the meter as Buffervalue versus Temperature. The SENTRON Bufferset is the factory set default. To change to another bufferset, in the Main menu go to “Config” and press ‘Enter’. Go to “Params”, press ‘Enter’ again. -
Page 21: Sentron Bufferset
SENTRON bufferset The SENTRON bufferset is the factory default setting. It is a set of 5 NIST-traceable, SENTRON provided buffers with pH values 2.00, 4.00, 7.00, 10.00 and 12.00 at 25 ºC. The full table of Buffervalue versus Temperature is given below. -

Note When performing a manual slope calculation, note that for an ISFET a theoretical sensitivity of 52,5 mV/pH should be used. 7.3.6. Calibration data The TITAN allows for storage, retrieval and export of the last calibration data sets. Following sections describe the various options available. 7.3.6.1. -

SENTRON Europe BV Manual TITAN Go to “Prev” and press ‘Enter’ to bring the previous calibration data set on the display. Similarly, “Next” brings the next data set on the display. The calibration data is shown, consisting of the probe status and the chosen bufferset. -
Page 25: Troubleshooting
“ATTxxx” will be shown on the status text line. The built-in helptexts will state the situation at hand and recommend a remedial action. In case of multiple messages, the TITAN itself handles priorities to make sure that only one ATT code is shown. - Page 26 SENTRON Europe BV Manual TITAN ATT006: The ISFET Check if the probe is in the right buffer. output is too Recalibrate using fresh buffers. close to the If this does not help, replace the probe.

Page 32: Cleaning Procedure
SENTRON Europe BV Manual TITAN 12. Cleaning procedure In many cases of returned probes, the probe does not work due to a polluted diaphragm. This is caused by the fluid in which the end-user is measuring. If the customer does not clean de probe regularly, the diaphragm will block the internal electrode. - Page 33 Representations and warranties made by any person, including dealers, representatives and employees of SENTRON, which are inconsistent or in conflict with the terms of this warranty, shall not be binding upon SENTRON unless in writing and signed by one of its officers.
