Aqua-Check 2

The Aqua-Check 2 is a highly sensitive and portable photometer, built for the precise determination of substances and there  concentration in water. As the device was equipped to measure a broad variety of water parameters, it responds both to industrial demands, and to those of the fishery, aquaculture and koi keeping sectors.
The Aqua-Check 2 draws upon the photometric procedure, which is eminent in physics and chemistry. The photometer sends light beams of a defined wave length through a water sample, which is especially coloured for this procedure. Using the measured change in intensity of the incident light , the device can meticulously establish the concentration of the parameter under investigation. Conventional tests commonly use cuvettes. However, as they may vary in wall thickness, or may be subject to impurities, measured values are often distorted. In stark contrast, the Aqua-Check 2 determines these values without cuvettes, ensuring precise measurements. Additionally, the photometer does not to be calibrated. Owing to its fully extensible measuring probe, a broad measuring range is at the Aqua-Check 2’s disposal. Hence, even miniscule concentrations of phosphate can be detected reliably. The Aqua-Check 2 is delivered with solutions for the titrimetric determination of total and carbonate hardness by default. Using the test kit included in its delivery items, a total of 390 individual analyses can be carried out. Although the pro equipment allows for environment-independent water analyses, it nevertheless ensures professional measurements.
The Aqua-Check 2 is powered by a customary 3-Volt coin battery, which allows for up to 1’000 individual measurements.

Delivered in its sturdy hard case, the entire analysis equipment is well protected, and can be transported with ease on field trips. The photometer, all necessary indicators, testing tubules, as well as the timer and safety glasses are always ready for usage, thanks to the neat arrangement within the hard case. Preparatory time for the measurement is thus minimal.
