Whether you’re verifying the accuracy of a temperature sensor or performing a procedure for the pharmaceutical industry, the Fluke Stik thermometer from Hart Scientific gives you a safe, portable, and accurate solution for all of your temperature calibration applications. The probe and digital readout are fixed together, calibrated as a system, and accurate to ±0.1°F (±0.05°C) over the full temperature range with selectable resolution of 0.1, 0.01 or 0.001. The instrument comes with an easy-to-read temperature trend indicator that you configure to meet your application’s stability requirements. The indicator tells you if your temperature is trending up or down and lets you know when your temperature source is stable enough for an accurate measurement. The highly accurate RTD probe is hinged and swivels 90° allowing you to easily view your temperature measurement from the large backlit LCD. The Stik Thermometer operates on three AAA batteries and includes a low-battery indicator and auto-off function that shuts down the thermometer to prevent erroneous measurements due to low battery life.
