Lovibond MD110 pool photometer 4in1
The MD 110 photometers are a new series of photometers replacing the older MD 100. They also operate to the DPD colometric standard.
MD 110 Photometers Compared to previous MD 100 photometers, the MD 100 has many new and improved features. The photometer measures the amount of light passing sequentially through a water sample coloured with a suitable tablet and then through an optical filter. The amount of light passing through is measured by the measuring module and compared with the raw water sample used for zero calibration of the photometer. The darker the colour of the sample, the less light will pass through it.
The MD110 photometer has integrated Bluetooth functionality. The AquaLX app is the ideal complement to the Lovibond photometer. Measurement results are transmitted via Bluetooth for quick evaluation or administration on smartphones or tablets. The app supports data export as an Excel-compatible CSV file.
Lovibond MD 110 photometer (4 in 1) - particularly suitable for testing spas and indoor pools, measuring 4 parameters: free and total chlorine, pH, cyanuric acid and total alkalinity (CL-PH-CYA-TA).

Jestem bardzo zadowolona z usług tej firmy. Każdy nam odmawiał pomocy, nawet firma montująca basen. Pool system zjawił się i doprowadził basen sprzed paru lat do stanu używalności, co więcej dokonał napraw uszczelniających co spowodowało ze basen stał się w pełni sprawny. Naprawdę polecam !

Bardzo miła i sympatyczna obsługa oraz fachowe doradztwo techniczne.

Bardzo profesjonalna i cierpliwa obsługa. Odbierają telefony, wszystko dokładnie wytłumaczą, wysyłają praktycznie na drugi dzień każdą część którą potrzebuje klient. Pan Krzysztof z serwisu rzetelnie podpowie co zrobić i jak rozwiązać swój basenowy problem, jeśli chcemy majstrować przy basenie sami. Pan Paweł i Marcin też skarbnica wiedzy technologii basenowej. Dobre ceny. Polecam firmę i pozdrawiam zespół POOLSYSTEM

Jak budujesz basen to to miejsce jest dla ciebie, osprzęt, doradztwo i miła obsługa.

Super obsługa doradzi pomoże,ceny na duży plus .Polecam
