Hanna Instruments HI93510N Waterproof Thermistor Thermometer with Calibration Option

The HI93510N Waterproof Thermistor Thermometer is a robust and versatile meter designed for indoor and outdoor use with interchangeable thermistor probes, including the HI762 series. It measures temperatures from -50.0 °C to 150 °C (-58.0 °F to 302 °F) with ±0.4 °C (±0.8 °F) accuracy and features a user-activated backlit LCD for easy visibility in any lighting. The meter includes a 0°C calibration function, HOLD and high/low tracking, and Hanna’s Battery Error Prevention System (BEPS) for reliable measurements. Its waterproof design makes it suitable for fieldwork, laboratories, and industrial applications.

  • Wide temperature range: -50.0 to 150 °C / -58.0 to 302 °F
  • 0°C Calibration Option: CAL button allows ice bath calibration for probe accuracy
  • Backlit LCD: Easy viewing in dim or bright conditions
  • Battery & durability features: BEPS, low battery indicator, waterproof construction

Description

The HI93510N thermometer is engineered for precise temperature measurement across a variety of environments, including field, laboratory, and industrial settings. Compatible with Hanna HI762 series thermistor probes, the meter can measure temperatures of air, liquids, semi-solids, surfaces, and gases. It provides high-resolution readings from -50.0 °C to 150 °C (-58.0 °F to 302 °F) with ±0.4 °C (±0.8 °F) accuracy, excluding probe error. Users can easily switch between °C and °F, freeze the display with the HOLD function, and monitor high/low readings continuously.

The HI93510N includes enhanced features such as a backlit LCD, a 0°C ice bath calibration button, and optional calibration test keys (not included) to ensure ongoing accuracy. The meter has a selectable auto shut-off (8 min, 60 min, or disabled) to preserve battery life, and Hanna’s BEPS system protects against low battery errors. Lightweight and portable, this thermometer is ideal for food service, environmental, industrial, and laboratory applications.

Features

  • C Calibration – A CAL button located on the face of the HI93510N allows the operator to calibrate the meter and probe in an ice bath at 0°C. This assures any error in the meter and probe interchange does not occur.
  • °C/°F Readout – Measurements can be displayed in either degrees Celsius or Fahrenheit. A simple press of the °C/°F button will switch between the two scales.
  • Backlit Display – The HI93510N features a user-activated backlit display that ensures readings are easy to view both indoors in dim lighting and outdoors in sunny conditions.
  • Interchangeable Thermistor Probes – A wide range of thermistor type probes are available to meet the specific needs of users. Hanna Instruments offers the HI762 series that includes probes to measure the temperatures of surfaces, gases, air, liquid, and semisolid samples.
  • High/Low Function – The maximum and minimum temperature values are continuously displayed along with current reading on the LCD display. To reset the high/low readings the “CLEAR” button is used.
  • HOLD Function – The HOLD button on the face of the meter freezes the display to allow the user time to record readings. Although the display is frozen, the meter continues to internally monitor the temperature and update the high and low measurement values.
  • Optional Calibration Test Keys – For measurements that are always reliable, thermometers must be calibrated periodically. Hanna offers calibration test keys (not included) to offer a fast and simple way of checking the accuracy of the HI93510N. By simply connecting the key to the probe input, the thermistor thermometer will display a reading; if the reading differs more than 0.4°C (0.8°F) from the key value, the thermometer should be recalibrated.
  • Automatic Shut-off – The HI93510N has a selectable automatic shut-off feature. The meter can be set to turn off after 8 minutes, 60 minutes, or disabled.
  • Battery Error Prevention System (BEPS) – The Battery Error Prevention System will shut the meter off when the battery power is too low for an accurate measurement.
  • Low Battery Indicator – When the battery level is below 10%, a warning symbol will blink to indicate low battery condition.
