Bench top Multi-Function Meters : Multi-Language, Dual Channel - Simultaneous Display pH, mV, Ion, ORP and Temperature Meter.

The multi-language, dual channel - simultaneous display pH, mV, Ion, ORP and Temperature meter has unprecedented resolution and accuracy (Up to 0.002 pH accuracy) for precise measurements. This versatile instrument has the ability to measure pH, mV, Ion, ORP and temperature all from the one meter - and with 0.5% Full Scale Accuracy! it can also store and recall up to an 250 Data Sets. The Series 5500 conforms to extensive GLP requirements such as Programmable Alarm, Context-Specific "HELP" Menu, Multi-Language Options and more. Advanced and sophisticated functions can be easily accessed via its scratch-resistant splash-proof extra-large LCD at a touch of a finger. Designed for optimum performance and versatility, this microprocessor-based benchtop meter provides the user with programmable options that can be customized to best suit individual's discerning requirements. 

Applications for the PH5500 multi function meter include:    

Laboratory/Industrial : 

Use for water quality testing, sewage treatment, food processing (for HACCP compliance), geological testing. Great for R&D and QC applications in the food and pharmaceutical industries, paper/pulp processing, chemical industries and related fields. Suitable for most ASTM and EPA test procedures.

Educational : 

Perfect for research labs, suitable for all types of chemistry labs and ecology studies.

  • Extra-Large Durable Touch-Screen LCD with Backlit provides optimum clear view of readings even at a distance 
  • Dual Channel allows user to measure 2 different parameters and view results on screen simultaneously 
  • High Resolution and Accuracy (up to 0.002 pH Accuracy) for precise measurement 
  • Multi-Point Automatic Calibration with Auto-Buffer Recognition (up to 5 points) for hassle-free operation 
  • Auto-Calibration ensures effortless operation with no calibration mistake 
  • Extensive Display Customization allows viewing of display based on individual preferences for easy and quick viewing 
  • Secured Setup Options explicitly restrict unauthorized tampering of meter settings with two procedural levels (advanced and basic) for discerning users' needs 
  • Context-Specific "HELP" Menu prompts and guides user throughout meter's operation with self-diagnosis messages 
  • Advanced Setup Menu allows programmable functions like pH resolution, stability, etc. and viewing of electrode diagnosis - pH slope/offset, previous calibration points. 
  • Multi-Language Options like English, French, German and Spanish offer user-interface universally for added convenience 
  • Automatic Temperature Compensation (ATC) for best accuracy under fluctuating temperatures 
  • Automatic Downloading of data into memory or computer via a cable at desired time intervals or whenever reading stabilizes 
  • Expanded Memory stores and recalls up to 250 data sets either manually or on programmable real-time intervals 
  • Built-In Real-Time Clock stamps stored data and calibration data with time & date - meets standards for GLP purposes 
  • High/Low Set Point Alarm alerts once reading outside preset limits 
  • Automatic Temperature Compensation (ATC) for best accuracy under fluctuating temperatures 
  • FET (Solid-State Non-Glass) pH electrodes can be used directly without adapter as well as specialty and standard glass pH electrodes 
  • RS232 Communication interface for downloading data to a printer or PC for report documentation 
  • Detectable Electrode Stand organizes multiple electrodes neatly and holds them firmly in place
