Agilent Keysight HP 44421A The 44421A is a Data Logger from Agilent HP. Data loggers, or
The 44421A is a Data Logger from Agilent HP. Data loggers, or data recorders, collect information over time for a variety of purposes. A data logger uses internal memory and sensors to gather and document information on a 24-hour basis. Receive an accurate and comprehensive picture of the environmental conditions you’re monitoring as the device logs this information around the clock. Use data logging to measure temperature, humidity, wind speed, solar radiation, soil moisture levels, road traffic, tank levels, and a number of other elements.
The HP 44421A (Option 10) is a 20-channel analog signal multiplexer assembly that is used to switch (multiplex) signals from up to 20 channels to the 3497A DVM or to other assemblies or instruments. Each of the 20 channels consists of three reed-actuated relays, one each for High, Low, and Guard lines. The channels are organized into two decades of 10 channels - one channel can be closed in each decade. Relays can be closed in a random fashion or can be incremented between programmable limits.
Because the 20-channel relay multiplexer has low thermal offset characteristics, this assembly is ideal for precise low-level measurements of transducers and temperature measuring devices. Since two channels (one per decade) can be closed at a time, one Option 010 assembly can be used to make four-terminal resistance measurements.
