Hanna HI-98161 General Purpose Foodcare pH and Temperature meter

Hanna HI-98161 General Purpose Foodcare pH and Temperature meter

Food products can provide a number of challenges for the user that needs to measure the pH. Food products tend to be semi-solid, solid or as a slurry with a high content of solids.


Hanna HI-98161 General Purpose Foodcare pH and Temperature meter

The HI-98161 is a rugged, waterproof (IP67) portable pH meter which measures pH and temperature using the FC2023 Foodcare pH electrode. The meter is supplied with all necessary accessories to perform a pH/temperature measurement. It is all part of a package in a durable thermoformed carrying case that holds the probes, meters and calibration buffers securely in place.


  • Waterproof – IP67 rated
  • Calibration
  • Automatic/ manual temperature compensation
  • CAL CheckTM – problem alert
  • 200-hour battery life approx x4 1.5V AA batteries
  • Calibration
  • GLP
  • Intuitive keypad
  • Auto hold
  • Clear display
  • Carry case and accessories

The Hanna unique CAL Check feature alerts the user to potential problems during the calibration process. Which is important for the food processor since it is likely that the probe will be coated with the solids found in the food product being measured. This said coating can easily lead to errors in pH measurement. The meter will inform the user with display prompts when the probe needs to be replaced, cleaned or if the pH buffer might be contaminated. The overall probe condition, after calibration, is displayed on the screen as a percentage from 0 to 100% in increments of 10%. The offset and slope characteristics of the pH electrode can affect the probe condition. Both the offset and slope characteristics can be found in the GLP data.

The FC2023 is supplied with the HI-98161 is designed specifically for measuring pH in food. All types of food samples will coat the sensitive glass membrane surface and/or clog the reference junction. The probe has a conic tip shape that allows for easy penetration, an open junction that resists clogging, and a Polyvinylidene fluoride (PVDF) food grade plastic body. The PVDF is resistant to most chemicals and solvents, including sodium hypochlorite. PVDF has resistance to fungal growth, high abrasion, ultraviolet and nuclear radiation and mechanical strength. The FC2023 is the ideal general purpose pH electrode for food products because it connects quickly to the HI-98161 with a waterproof DIN connector that allows for a secure non-threaded attachment.

This product comes with a 2 years warranty and 6 months for the electrode.
