Great results, high accuracy and easy to use
Rating: 4.7

  • Application Area:Alkalinity titration

"We used for the determination of total alkalinity by acid-base potentiometric titration method described by Dickson et al. (2003) and Hernandez-Ayon et al., (1999). We pre-conditioned the equipment by performing seawater measurements to condition the pH electrode and calibrated the electrode with the standard of seawater buffers and we have excellent results"

Nice output, using it constantly.
Rating: 4.3

  • Application Area:Titrate solutions and suspensions

"I am abusing the setup for my own applications and find it easy to operate. It is possible to generate macros that allow reproducible conditions. The pH electrode I use with it was also from Metrohm and is very stable and reliable. I have been adjusting the set-up somewhat to make it more suitable for my purposes. The software and data output also need some adjustment, but in the end, I can get everything I want. I find the Value for Money a bit too low. From my point of view, this could be somewhat cheaper, but anyway, it is robust and stable and I have been using it for years now. I guess I would buy it one more time."

Great results. We could not work without it.
Rating: 4.7

  • Application Area:in vitro digestion - pH stat

"We work in research and we have a pH STAT Titrando 902. We adapt it to perform in-vitro digestion of food. It is very useful to maintain the pH automatically in each phase of the digestion process. Especially to control and study lipid digestion. The software is easy to use and the results are reproducible given the effectiveness of the pH controls. All the advantages mentioned are in accordance with the price of the equipment. Moreover the Titrando pH STAT is very useful to assess the activity of the enzymes involved in the digestion process, control agitation, dosages of small volumes and to study the bioavailability and bioavailability of bioactives in food."

Excellent instrument for fast and precise pH determinations.
Rating: 4.3

  • Application Area:Marine acidification

"In my research lab, I use this for pH determinations and alkalinity titration as an easy way to obtain fast and precise results. We also use it for our calibration curves as it is an important component in the lab of chemical oceanography. It is very easy to use; students can work and use it without any problem. Another positive point is the easy way you can take care of it, but the best of all is the relative cost-benefit - you can purchase a very useful product at a very reasonable price."

  • Application Area:Acid-Base Titrations

"This is a complex set-up that allows many things, but for our purpose of acid-base titrations it is over dimensioned. A simpler device is not available commercially though, because these kinds of titrations are rather uncommon. We try our best to adapt, but some things are very non-intuitive in the software. One good thing is that routines can be written to get what you want, but it takes some time to get used to that way of thinking. "

Review date: 18 Feb 2014 | 902 Titrando – pH STAT Titrator and Synthesis Controller
The 902 Titrando expands the Titrando system by adding the modes pH STAT titration and controlled dosing.

STAT titration

The determination of the activity of an enzyme or the monitoring of the release kinetics of antacid drugs requires a titrator that rapidly adjusts a predefined pH value and keeps it constant over a long time period. The 902 Titrando's controller has been optimized for this task and is among the best available on the market.

Tandem dosing is a new feature offered by the 902 Titrando. To avoid a break in dosing when the buret is refilled, a second buret takes over the dosing operation without any interruption. This means that fast reactions and those that have a high reagent consumption can be monitored without any loss of accuracy.

Controlled dosing

The tasks to be performed in the synthesis laboratory differ from those in titration. Typical synthesis work involves maintaining constant a pH value or performing a multiple dosing operation under strictly defined conditions: A preset volume has to be added to a solution during a given time span. During the controlled dosing procedure, the parameters pH (or potential) and temperature are continuously monitored and registered. This results in a complete documentation of the synthesis sequence.

Dosing can also be carried out continuously in the tandem mode with two Dosinos.

Compatible with all existing sensors

Despite its new digital measuring interface and intelligent sensors, the Titrando with combined analogue and digital measuring amplifier also supports conventional sensors. This consists of one high-impedance and one polarised measuring input, a separate reference input and an input for a Pt 1000 or NTC temperature sensor. The resolution of the inputs is 0.1 mV or 0.001 pH. Up to two galvanically separated measuring interfaces can be installed.


A new feature of the 902 Titrando is its ability to perform control tasks. External instruments can be controlled by means of freely programmable TTL signals or by communication via RS 232 interface. This opens up the possibility of remotely controlling external heating or cooling apparatus, pumps or similar devices.
