AM3 Humidity . Temperature . Dew Point Indicator INSTRUCTION MANUAL
The ROTRONIC AM3 is a humidity and temperature indicator designed to operate with ROTRONIC HYGROMER series probes or external transmitters. It features dual input capabilities for measuring relative humidity and temperature simultaneously, as well as calculating dew point values based on probe data.
Users can control the device using blue and red push buttons to switch modes, freeze displays, record minimum/maximum values, and manage power settings. The unit supports RS232 output for connecting to personal computers via a provided cable, allowing for data logging and analysis using compatible software.
