Low Thermal Voltage Relays

Low thermal reed relays can switch low voltages in the low microsecond (µV) range. And reed relays switch these low voltages without altering the signal level. Even after it has passed through the relay. Low thermal relays are used in transducers. Transducers that produce very low voltage signals and need to be both switched and amplified. Moreover high end multimeters use low thermal reed relays. And switching thermocouples in data acquisition systems. Temperature measuring, data logging and measurement applications all use low offset voltage relays. The BT/BTS series are an excellent choice over semiconductor relays.
