It is often necessary to take temperature measurements with different types of thermocouples (K-J-T).
To make this possible, Hanna Instruments developed HI 93551 and HI 93551N, equipped with a button that switches between K-type, J-type or T-type thermocouples, giving them the power of 3 meters, all in one unit. These portable instruments can read with a resolution of 0.1 in an extended range of -149.9 to 999.9°C or -24.9 to 999.9°F; once only possible in sophisticated bench equipment used in research labs. The meters are also equipped with a dual level LCD that shows measured high and low temperatures along with the current reading. To freeze the display for easy recording, simply press the HOLD button. A °C/°F button will toggle between Celsius and Fahrenheit. These instruments have a low battery warning feature and a Battery Error Prevention System (BEPS). For even greater accuracy, HI 93551N features a CAL button to allow you to calibrate the meter and probe in an ice bath at 0°C. This will assure the removal of the combined meter and probe interchange error. HI 93551R also features RS232 output for transferring measurements (once every second) to devices with RS232 input (PC or printer). Hanna Instruments offers a wide range of K-thermocouple probes to meet your specific application (HI 766 series).
