Fluke Calibration 1502A/1504 Thermometer Readouts

Best performance thermometers in their price range

  • Two Tweeners to choose from—reading PRTs or thermistors
  • Battery packs available
  • Best price/performance package

One of Hart’s best-selling products is the Tweener thermometer, and there’s a reason. No other company, not one, has a reference thermometer that comes close to the performance and features of the Tweener for anywhere near its price.
