Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4278A #9034849 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4278A is a precision laboratory electronic test equipment that uses precision thermistors and is designed for accurately measuring low-level resistances. It features a wide range of resistance measurements, from 10 ohms up to 10 megohms with up to four digits of resolution. It has a number of features that make it suitable for accurately measuring low-level resistances. HP 4278A uses a four-terminal sensing technique, enabling it to eliminate errors from external sources or the test-lead resistance. It is powered by either a single-phase AC line or a DC voltage supply so that it can be connected to a wide range of test sources. AGILENT 4278A also features an additional internal-sensing terminal for measuring current and counter-electromotive force (CEMF) to eliminate thermal and contact voltage errors. 4278A also has a wide operating range, from -50°C to +50°C, so it can be used in a variety of environments. It provides a number of input protection circuits to protect it from transient voltages or excessive current. Additionally, it has an internal temperature compensation to ensure accurate measurement data even when ambient temperatures change. KEYSIGHT 4278A is a reliable, precise, and accurate electronic test equipment. It contains an internal high-stability oscillator and a low-noise operational amplifier to provide stable, repeatable results. It also features a wide input range from 10uV to 6V allowing for high-precision measurements without further amplification. It also features an external trigger input for external control of the measurement process. In addition to HEWLETT-PACKARD 4278A, HP also offer a range of accessories which can extend the range and capabilities of the device. These include additional temperature probes, power supplies, and test leads. Overall, AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4278A can offer laboratories, universities, and industry reliable and accurate electronic measurements of low-level resistances.
