Real UV254 Analyzer – M3000 v 2.1 10 4-20 mA Setup The Real UV254 M3000 is equipped with a 4-20 mA output capability. The 4-20 mA can be set to produce a user selectable UVT or UVA value for the low (4 mA) and a separate value for high (20 mA) up to 110% UVT.
Real UV254 Analyzer – M3000 v 2.1 11 RS-232 Data Logging The Real UV254 M3000 has the capability to data log various performance variables on a local computer via an RS-232 interface. The data log frequency as well as the specific data to be logged is configurable.
Real UV254 Analyzer – M3000 v 2.1 If your system has a Dual Feed accessory (and optional turbidity compensation is still in effect), the ASCII string would be slightly different. UVT is replaced by UVT 1 and 2, which correspond to Stream 1 and 2, and % Removal.
Real UV254 Analyzer – M3000 v 2.1 12 Slope Correlation Method The following method can be used to correlate the UV254 data to the parameter of choice such as TOC, COD, etc. Note that for many applications the absorbance reading of the M3000 can correlate very well with standard water quality parameters.
Real UV254 Analyzer – M3000 v 2.1 13 Dehumidifier for Humidity Control The Real UV254 M3000 includes a dehumidifier to control the humidity inside the monitor. Standing upright in a holder at the bottom left corner of the monitor as pictured in Figure 13.1, the dehumidifier maintains low relative humidity (RH) to prevent condensation from forming on the quartz flow cell walls.
