The 44705A is a Data Logger from Agilent. 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 Agilent HP 44705A is an analog signal multiplexer used to switch signals from up to 20 inputs for measurement by model 3852A voltmeter accessories or by external voltmeters. This accessory provides switching capability for up to 20 inputs at scanning speeds up to 450 channels/second using 3852A voltmeters. The accessory can switch signals up to 120 VDC or 120 Vrms (170 Vpeak).
The Agilent HP 44705A consists of a component module and a 20-channel terminal module. Field wiring from user sources, such as voltage sources, is connected to the terminal module, and signals are sent to the switches on the component module. Each channel can be independently configured to allow multiple functions to be measured using the same accessory.
