According to Hanna Instruments , HI 93530 and HI 93530N are waterproof thermometers that use a powerful microprocessor to linearise the response of the thermocouple to achieve high accuracy and resolution.
These instruments can read with a resolution of 0.1 in the -149.9 to 999.9°C and -24.9 to 999.9°F ranges. The meters are equipped with a HOLD function that freezes the current reading on the LCD. A °C/°F button will change between the Celsius and Fahrenheit ranges. An important feature where measurements are necessary in degrees Celsius as well as Fahrenheit. HI 93530N has a CAL button to allow the operator 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. In addition to the calibration feature, HI 93530N features a user-activated backlight for low light conditions. Remaining battery power is displayed at start-up and a low battery warning signal and error prevention provides advanced power management to both instruments. A wide range of thermocouple probes are available for applications such as liquid, air and semisolids.
HI 93530 is supplied complete with batteries, protective case and instructions. HI 93530N is supplied complete with batteries, protective case and instructions.
