Hanna food quality pH meters are rugged and portable with the performance and features of a benchtop. Five models are available to measure food, milk, meat, yogurt and cheese. Each model is supplied with an application specific electrode, cleaning solutions and a durable thermoformed carrying case that holds the meters, probes and calibration buffers securely in place.. These waterproof meters comply to IP67 standards and can be easily operated with one hand. 

Features:

• Ergonomic, rugged, waterproof (IP67) design
• Supplied with Foodcare pH/Temperature electrode
  • See tip types and product images below
  • Open junction design that resist clogging from food solids
  • Built in temperature sensor for temperature compensated measurements
• Five-point pH calibration with seven standard buffers and five custom buffers
• CAL Check:
  • Alerts user to potential problems during calibration including when to clean electrode and possible buffer contamination
  • Displays overall condition of the pH electrode after calibration that is based on the offset and slope characteristics

• Log-on-demand: Stores measurement data at the press of a button
• AutoHold: Freezes displayed measurement reading upon stabilization
• GLP Data storage; including date, time, pH calibration buffers, offset, and slope
• Calibration timeout to alert the user at a defined interval when the calibration has expired
• Multiple language selection
• 200 hour battery life with battery level displayed on measurement screen
• Menu driven for ease of use with virtual-key extended functionality
• Contextual help at the press of a button
• Backlit, graphic LCD
• PC Connectivity
