As well as offering all sensor functionality and equipment of the DL200H, the DL200L also provides an additional NDIR sensor for detecting concentrations of CO₂ in the room air.
For long term logging of environmental data and carbon dioxide values, the DL200L, with its alarm function, is the ideal air controlling instrument for workspaces, for example, in schools, public authorities and businesses.
Definition of measurement channel – How many measured values can be recorded?
All devices from the DL series are powerful multi-channel data loggers with which you can not only detect, but also record all of the compatible measured values (see technical specifications).
The term “measurement channel” is not used to mean the same as it is by some of our competitors – meaning the available sensors, but instead – the same as in analysis software – it means one individually selectable “recording track”, i.e. the value which should be logged.
For each measured value and measured unit (channel group), one or more of the four following types of measured values can be recorded: current, minimum, maximum or average. Each of these four values represents a measurement channel.
The maximum amount of available measurement channels for each data logger is thus the amount of detectable channel groups (e.g. temperature in °C) multiplied by the four types of measured values.
In total, 20 of these measurement channels can be freely selected for logging and three for being displayed.
