The PCE-CP 20 is a versatile and portable instrument designed for analyzing various water parameters. This multi-functional device allows for a wide array of liquid analyses, enabling the user to assess levels of substances such as alkalinity, chlorine, cyanuric acid, and pH. To conduct an analysis, the user needs to place a 10 ml water sample into a cuvette. The device is equipped with an integrated LED that emits test light at wavelengths of 503 nm, 570 nm, and 620 nm. The measurement is determined by a photodiode that detects the light passing through the sample, providing accurate readings based on light transmission.
The multi-parameter water analysis meter automatically records each measurement it takes. These saved data points can be conveniently accessed and analyzed via a mobile device, thanks to the meter’s integrated Bluetooth connectivity. To facilitate this, a complimentary app is provided for mobile analysis of the data. Additionally, a Bluetooth link can be established with a computer, for which free software is available to examine the measurement results. Another notable feature of this device is its ability to upload the collected data to a cloud service. This enables users to access their data from any location, and this cloud service is provided at no extra cost.
