If cuteness were reason enough to buy a product, Fluke Calibration's Mini Fixed-Point Cells would win you over easily. But there’s a much better reason to buy them: they give you the least expensive, easiest-to-use fixed-point standards for your lab.
Mini cells eliminate the need for comparison calibrations. Temperatures of fixed-point cells are constant and intrinsic, so only the electrical parameters of the sensor under calibration need to be read. If you’re calibrating industrial thermometers, thermocouples, or thermistors and want the most accurate calibration possible, these mini cells will give it to you. If you need a wide range of temperatures, mini cells cover the triple point of water (0.01°C) and every ITS-90 point from indium (156.5985°C) to copper (1084.62°C).
• Lower uncertainties than comparison calibrations
• All ITS-90 fixed points from TPW to copper
• Reduced equipment and annual recalibration costs

Uncertainty (mK) k = 2
1Distance from the bottom of the central well to the surface of the pure metal.
2"Cell Only" refers to the expanded uncertainty of the cell when realized by traditional methods and maintained using traditional maintenance devices. “Simple Realization refers to the expanded uncertainty of the cell when realized using practical methods (melting points instead of freezing points or slush ice instead of an ice mantle, for example) and maintained using Hart’s 9210 and 9260 mini cell maintenance apparatus.
