Saluki SE1022D DSP Lock-In Amplifier (Dual-channel)
-
SE1022D Digital Lock-in Amplifier provides an excellent performance within its bandwidth from 1 mHz to 102 kHz. More importantly, SE1022D has dual independent input channels and dual independent high precision signal generators. Each input channel and signal generator can be used independently which means that the SE1022D is equivalent to two traditional lock-in amplifiers. Moreover, due to the twin symmetrical design, the two independent input channels and signal generators have ultra-high synchronicity, which meets the measurement requirements demanding extremely high synchronization.

Basic Quad J-Type Analog Thermocouple Amplifier
SEN-30103-J0
-
Analog thermocouple amplifier board based on the AD849x from Analog Devices (successor of the AD597). This quad-channel thermocouple board converts the very low voltage signal from a thermocouple to a highly-linear, 0.005V/C output with either 0V or 1.245V offset (both configurations stocked) while removing unwanted noise from the signal. Many supply and output configurations are available with this board, though the PCB was designed with Arduino in mind. Specifically, the output header will plug directly into a standard Arduino Uno or Mega, with a pin-for-pin match for power supply, ground and analog outputs. With a 5V Arduino, temperatures from 0C to 1,000C are possible with the 0V offset board and -249C to 750C with the 1.245V offset board. If using a 3.3V microcontroller (Due, etc), the board must be supplied with no more than 3.3V to avoid damaging the microcontroller. Temperature measurement range is dependent on the supply voltage. It is possible to supply the board with higher voltages to allow temperature measurement over the entire operating range of the K-Type and J-Type thermocouples, allowing use with more capable data acquisition equipment.
