HACCP and Food Quality pH Meters

Hazard Analysis and Critical Control Points program requirements for the Food Industry dictate monitoring of pH, temperature and other factors in food production and storage areas.  Hanna Instruments has specifically designed pH meters to achieve these goals.  Good Laboratory Practice (GLP) technology is also built into many of these products.  Many of these instruments have built in printers and or data logging capabilities to satisfy record keeping requirements.  To learn more about how the role pH plays in food production, a short article is included in the "Tech Info" section of this website: "pH and Food Quality."

We highly recommend using a bench meter: Hanna Instruments Calibration Check pH meter with or without an attached printer (HI 120 or HI 122).  In every case, please check with MBH Engineering Systems engineers to insure that you get the proper electrode for your application.

Two portable meters shown below are also good choices for this application.  Other instrumentation for the Food Industry includes: salinity, temperature and humidity monitoring.  Specialized equipment is also shown on this website for the wine industry.

Waterproof HACCP pH Meters: HI 99161

 

 

 

Waterproof, Heavy-Duty pH Meter

  • Specific for HACCP & Food Quality Applications
  • Ideal for Wet & Humid Conditions
  • Conic Tip for Use in Semisolids Such as Meat & Cheese


HI 99161
�s waterproof casing provides excellent protection from water and humidity, typically present in the food industry. HI 99161 is supplied with the FC 202D pH electrode with built-in temperature sensor, specially designed for use in the food sector. This electrode features a rugged, easy to clean, PVDF body that tapers to a strong conic tip ideal for measurements in semisolids such as meats and cheeses. The electrode has a free diffusion sleeve type reference junction which prevents the typical problems of clogging in viscous liquids or samples with high solids content such as milk or condiments. The electrolyte used in the FC 202D electrode is free from the poisonous silver chloride, which prevents food contamination by the electrode. HI 99161 allows automatic calibration at either NIST or standard buffer sets with auto recognition and a stability indicator. The temperature is continuously displayed on the secondary level of the large LCD. The meter runs on common 1.5 AA type batteries and the LCD provides a low battery warning signal.

HI 99161 is supplied with FC 202D pH electrode, pH 4 & pH 7 buffer sachets, HI 700642 cleaning solution (2 x 20 ml), batteries, rugged carrying case and instructions.

Printing and Data Logging pH Meters: HI 98230

 

 

 

Printing and Logging pH/Temp Meter with GLP

  • Intelligent electrode technology for reliable measurements
  • Powerful meter in a small package
  • Password protection secures GLP data


The top-of-the-line HI 98230 and HI 98240 pH meters offer many advanced features engineered into a highly portable meter, with the added advantage of having a built-in plain paper printer, logging and log-on-demand. Featuring GLP (Good Laboratory Practice) capabilities, these instruments incorporate the HANNA instruments
� intelligent electrode technology. All these features make HI 98230 and HI 98240 ideal for on site as well as field laboratories. HI 98230 and HI 98240 are the perfect solution for any application where pH measurements need to be recorded. In fact, data can be stored or printed directly on demand or automatically. The stored data (up to 100 measurements on-demand and up to 1500 automatically) can also be downloaded to a PC with a standard RS232 serial connection and Hannas infrared adapter and HI 92000 Windows compatible software (not included), which permits the transfer of data to other programs.

HI 98230 and HI 98240 are supplied complete with HI 1618D smart pH electrode with internal temperature sensor, pH 4 and pH 7 buffer sachets, electrode cleaning solution, 5 paper rolls, batteries, 12 Vdc power adapter, rugged carrying case and instructions.
