It is often necessary to be aware of the highest and lowest temperatures measured during a certain process.
For this reason, Hanna Instruments has incorporated a dual-level LCD into these portable instruments. Along with the current reading, the highest and lowest temperature in the series can be assessed at a glance. These thermometers can read with a resolution of 0.1 in the range of -149.9 to 999.9°C or -24.9 to 999.9°F. The meters are equipped with a HOLD function that freezes the current reading on the display. A °C/°F button will change between Celsius and Fahrenheit modes. Battery level is shown at start-up and low battery warning with Battery Error Prevention System (BEPS) assure long periods of trouble-free use between battery changes. HI 93531N also features a backlit LCD and can be calibrated at one point with a simple ice bath by pressing the CAL button. HI 93531R is the top of the range model, featuring RS232 output for transferring measurements (once every second) to devices provided with RS232 input (PC or printer). Hanna Instruments manufactures several thermocouple probes for different applications (HI 766 series).
HI 93531 is supplied complete with batteries, protective case and instructions. HI 93531N is supplied complete with batteries, protective case and instructions. HI 93531R is supplied complete with batteries, protective case and instructions.
