Analite 390 Series SDI-12 Turbidity & Temperature Probe

The Analite 390 digital series probe incorporates the same ISO7027 90 optics, wiper, housing and cable options as the Analite 9000 Analog Series, but includes RS232 and SDI-12 digital outputs that offer a host of advanced signal processing and control features. Data output includes mean, median, sample variance, minimum, maximum turbidity, which are measured over 100 samples, as well as internal probe temperature and supply voltage. One probe offers user selectable ranges of 40, 100, 400 and 1000, and may be calibrated at any time or have later firmware uploaded via an RS232 interface.

Analite 390 Series SDI-12 Turbidity & Temperature Probe

The 390 series has been enhanced to include the 391 & 396 options which bring together all of the features of the digital 390 probe with the simplicity of the analog 9000 series probe. The 391 and 396 incorporate a dual analog output. Select from either 0 to 1 volt, 0 to 2.5 volt, 4 to 20 mA or 0 to 20 ma. All functionality is user selectable via the RS232 interface. A summary of the available 390 series probes is listed in the below table:
