Realtech M3000 on-line UVT analyser
The Realtech M3000 on line UVT instrument continually reports the %UVT so the UV sterilisation process may be automatically controlled.
Realtech instruments are installed to control the UV sterilisation process to ensure the correct intensity of UV sterilisation is achieved according to strict regulations.
The % transmission is affected by the amount of chemical contamination in particular organic species and the amount of suspended solids within the sample.
The analogue output (4-20mA signal) from the M3000 instrument may be connected to a PLC to control the intensity of UV light used to treat and sterilise potable water. The instrument is provided in a surface mount enclosure proving ingress protection to IP65 and integrates a local display with tactile keypad.
The instrument compares two seperate absorption measurements using a 10 and 20mm pathlength (at 254nm wavelength) which minimises the effect of calibration drift and the effect of cuvette fouling, should it occur.
Automatic acid cleaning is available as a cost option to removing fouling and reduce manual intervention.
Realtech also manufacture a portable P200 instrument which can be used to verfiy the on-line analyser and calibrate if necesssary.
