Keithley 7700 Digital Multimeter for RTD, Thermistor, Thermocouple

The 7700 from Keithley is a 20‑channel differential multiplexer module designed for use with RTDs, thermistors, and thermocouples. Integrated seamlessly into data acquisition systems, it allows measurements from multiple sensor types with high flexibility, enabling temperature and resistance monitoring across many points without needing separate wiring or hardware per channel. With its robust design, Keithley ensures reliable connections, low measurement drift, and consistent performance under varying environmental conditions. It’s an excellent accessory for labs, test fixtures or industrial control setups that demand multiplexed data collection.

What Makes the Keithley 7700 Differential Multiplexer Module Standout?

The Keithley 7700 shines because it consolidates up to 20 differential channels in a single module, enabling simultaneous RTD, thermistor and thermocouple inputs. This reduces wiring complexity, improves throughput, and enhances measurement flexibility. Its ability to work cleanly across different sensor types with reliable switching performance makes it especially beneficial where multiple sensor inputs are involved and precision is crucial.
