Reliable Kit
Application Area: Analysing Moisture level in Freeze Dried products
"We use the 899 Coulometer along with the 860 Thermoprep ovens. The device is easy to use and gives reproducible results. Metrohm is helpful when I contact them with issues and remind us when the annual service is due. The only downside to the device is how easy it is to accidentally reset the device to factory settings. Holding the 'on' button for too long brings up the 'factory reset' page. As there is a countdown timer on this page, the user can panic at this point and press the 'back' button. Unfortunately, the 'back' button is the button used to confirm the factory reset."

Metrohm will always be my go-to supplier.
Application Area:Analyze mineral insulating oil
"The instrument has proven effective in the analysis of mineral oil. As a laboratory, we have had to change reagent suppliers multiple times due to no contracts in place, however this piece of equipment has proven its worth no matter the quality of reagents used. Reproducibility is quite good with an average of 3 injections per sample. The Metrohm SA team is well informed and literally everyone; applications, sales and service can assist over the phone with troubleshooting. Metrohm equipment provides peace of mind to the end user. We don't even know why you still make instruments, your equipment lasts forever!"

Best instrument for analysis.

Coulometry is the ideal method for water determination in fluids, solids and gases when it comes to water determination in the trace range (10 µg to 10 mg absolute water). Moreover, coulometry is an absolute method and thus no titer determination is necessary.
Small and compact
The 899 Coulometer is the smallest Metrohm coulometer. The magnetic stirrer is already built in and a support rod can be dispensed with, thanks to the titration cell holder. The titration cell stands securely attached on the 899 Coulometer.
Automatic titration start
It can readily happen that the sample is added to the titration vessel without starting the titration beforehand. In such cases, the conditioning continues to run until the reagent is once again titrated until it is dry. Recalculations are not possible and the determination must be repeated. This costs sample and valuable time.
The 899 Coulometer offers an automatic titration start. The titration starts automatically, as soon as sample is added to the titration vessel.
Flexible with accumulator
A Power Box can be obtained as an optional accessory for the 899 Coulometer. This ensures impressive flexibility. Determine the water content of your samples, wherever you like.
