DFP - Digital Humidity and Temperature Analyser

DFP -
Digital Humidity and Temperature Analyser

The digital humidity and temperature analyser DFP helps to determine the relative humidity of pressurized air at the cable pressure section of pressurization systems. It replaces the formerly used LANCIER psychrometer (Order no.005767.000).

Since the allowed relative humidity in pressurised air ist depending on the temperature, the DFP is a combined temperature and humidity analyser. First itindicates the temperature value, then the humidity. A diagram shows at a glance, whether the measuredv alues are in the allowed range.

The DFP comes in a carrying case with quickconnector, hose and a battery.
