Measurable Parameters

The MD 150 Photometer allows measurement of the main parameters used in water control:

• 
  Free and total chlorine: 0.02 – 6.0 mg/l Cl2
  


• 
  Cyanuric acid: 10 – 200 mg/l CyA
  


• 
  pH: 6.5 – 8.4
  

The instrument's photometric range is between 0 and 3 Abs.

Measurement Technology

The system uses LED optics with a spectrometric sensor and anti-interference filter, in the planned variants.

The available wavelengths are:

415, 445, 480, 515, 530, 555, 590, 630, and 680 nm.

This configuration allows the instrument to perform photometric measurements dedicated to the various parameters provided.

Memory and Data Transfer

The MD 150 has a circular internal memory for 100 data sets, useful for storing measurements taken during control activities.

The USB-C and NFC communication interfaces allow for more practical data management and facilitate the transfer of information to compatible devices.

IP67 Protection Rating

The photometer's structure has an IP67 protection rating, a particularly useful feature for professional use in environments where the instrument may be exposed to water, humidity, or demanding operating conditions.

The intended operating range includes temperatures from 5 to 50 °C and relative humidity from 30 to 95% RH.
