Product information "Testoval® Colour Comparator Sulfite"
Replacement color comparator without cuvette, for the concentration range 0–20 mg/l SO32-.
Thanks to the Testoval color comparator, you can continue sulfite measurements without purchasing a new test kit. Due to its compact design, the device is ideal for mobile use and laboratory applications.
The Testoval color comparator from Heyl is used for the fast visual evaluation of water samples in sulfite determination. It is optimally matched to the corresponding Testoval reagents and enables direct assessment of concentration through color comparison.
After the reaction of the sample with the reagents, a characteristic coloration develops. This is compared with the stored reference values in the device, allowing the sulfite content to be determined easily.
Your advantages with the color comparator
Thanks to its compact design, the device is particularly practical for mobile use and is equally suitable for daily use in laboratories or technical systems. For these reasons, the device is lightweight and easy to use without prior knowledge of chemistry or extensive training. It can be used independently of power supply and electronic measuring devices.
The individual values 0.5 mg/l, 1 mg/l, 2.5 mg/l, 5 mg/l, 10 mg/l and 20 mg/l can be read by optical color comparison. The scope of delivery includes only the color comparator for simple concentration determination.
