Microvolt DC Volt Meter
QA350
The QA350 relies on a built-in reference to calibrate the ratio between the hi and low ranges. If you have a preferred lab reference, you may use that it to improve the QA350 accuracy beyond the indicated +/- 400 PPM. For example, various vendors on eBay can provide calibrated +/-30 PPM 5 or 10V voltage references that can be used to set the ultimate accuracy of the QA350 to under 50 PPM at room temperature.

Industrial Calibrators
A temperature calibrator, often called a thermometer calibrator, is used to correct inaccuracies in installed thermometers and temperature sensors, because temperature measurement is a critical parameter in many industrial processes. Although simulators are sometimes called temperature calibrators or thermometer calibrators and may be used to provide thermometer calibration for the electronics in an installed system, a temperature source with a calibrated reference sensor is still required to provide a complete and meaningful calibration. Fluke Calibration industrial and field temperature calibrators include: Metrology Wells; Field Metrology Wells; field dry-well calibrators; handheld dry block calibrators; Micro-Baths; large target infrared calibrators; field IR calibrators; ice-point dry-well; and thermocouple furnaces.

8 Channels Thermocouple, LV A/D
TC1
A thermocouple is a temperature-measuring device typically consisting of two dissimilar conductors that contact each other at one or more spots. It produces a voltage when the temperature of one of the spots differs from the reference temperature on other parts of the circuit. Thermocouple temperature sensors are widely used for measurement and control, and can also convert a temperature gradient into electricity.
