LogIT

1 COLORIMETER SENSOR This is an easy to use sensor which has a three colour solid state LED light source of known Red, Green and Blue bandwidths which are passed through the sample and measured by a visible light level sensor. Ideal for experiments concerning Beer’s Law, Lambert’s Law, sample testing and rates of reaction. Transmittance Range: Typically 0.0 to 110.0%T. Absorbance Range: 0.05 to 1.05 Abs. Cat No. Description Type Price Per DAT-350-175 Colorimeter Sensor Other 110.11 ea. Why not use LogIT Datalogging for colorimetry: LogIT Colorimeter Sensor can be used via Black Box or Observer Dataloggers to collect the readings. Using Observer allows experimentation away from a PC or iPad: data can be observed on the screen whilst recording and downloaded later. Alternatively it can be streamed live to an iPad. Direct connection to a PC via Black Box will provide results on the PC whilst recording.

LogIT Observer

LogIT Black Box

2 LOGIT OBSERVER The complete instrument for the modern science lab. Working with up to 4 sensors at a time, it will show readings on its bright clear screen as a meter display or, at the touch of a button, it will record them into its built in datalogger memory and display them as a graph. Observer can also be used a laboratory timer.
