5R7-570(A) RoHS compliant open board electronic temperature controllers are designed with a proportional integral control algorithm to provide control to thermoelectric modules (Peltier). H-bridge temperature control provides transition between heating and cooling. Green LED for heat and blue LED for cooling indicate mode; simultaneous illumination indicates the load circuit is off due to an open sensor. Pulse width modulation controls power level in thermoelectric module at a base frequency of 1Khz. Power resolution is one of ±250 steps in the load circuit control. Temperature controller is 1.75" x 3.5" x 3" with input voltage of 6 to 28VDC, output voltage of 0 to 36VDC, load current of 0.1 to 12.5A, 450W output power control, control stability of ± 0.1°C, and temperature range of -20° to 150°C.

Model 821HH handheld 2kV electrostatic voltmeter enables voltage measurement – in contacting or non-contacting mode – with reportedly zero charge transfer. Is part of Infinitron product line for measurement  of site-specific voltage on devices and materials sensitive to ESD during handling and processing. Probe tip assumes voltage level of the measured object's surface as the tip approaches. Applications include semiconductors, photovoltaics, LEDs, and other electronic devices, as well as materials research. Can be used to measure both conductive and insulative surfaces. Includes measurement range of 0 to +/-2 kV DC or peak AC, input resistance greater than 1x10E+14 ohms, input capacitance less than 1x10E-14 farads, speed of response less than 500us for a 1kV step, and voltage display accuracy of better than 1% of full scale.

Dual solder nozzle is for the selective soldering process. Two different size solder nozzles operate in tandem; a circuit board with different size components can be processed in one pass. Solder nozzles are 3mm or 6mm and 12mm or 18mm. Nozzles operate independently within a single soldering program.  Each nozzle is powered by its own programmable pump; solder volume and wave height can be set for a particular nozzle or printed circuit board assembly.
