Field/Laboratory/ Industrial

Instruments, Controllers & Sensors



IP67 Waterproof Portable pH / Conductivity (EC) / Total Dissolved Solids Meter for cooling tower water, boiler feed water, brines, rise tanks, pollution control, incoming process water and all types of water quality testing.

The CyberScan PC300 meter is the ideal choice for anyone requiring to take pH, Conductivity, Total Dissolved Solids (TDS) & Temperature readings.  This instrument can read all of these parameters and automatically recognises the type of sensor connected and selects its appropriate function. Tis meter is ideal for rugged outdoor field work or in situ Plant and Process applications - being waterproof and robustly built, the chance of accidental damage is virtually eliminated.  Not only is this instrument waterproof but in the event of accidentally dropping it into liquid, it will float to facilitate easy retrieval. These accurate instruments have many advanced features such as : Multi point push button calibration (up to 5/6 points) with auto buffer recognition - choice of USA, NIST or DIN pH buffer standards for quick calibration with no calibration mistakes, Displays previous calibration points and Built-in real time clock. 

Applications for the CyberScan PC300 meter include :

Industrial : 

For checking metal finishing, cooling tower water, printing fountain solutions, boiler feed water, brines, rise tanks, ponds, pollution control, recirculating systems, waste water and industrial process systems. Useful for food analysis and quality assurance testing.

Water Quality Testing : 

For analyzing water hard water, drinking water, effluent water, and incoming process water. Ideal for all types of quality assurance and water quality testing.

Environmental / Agricultural :

For ecology studies, aquaculture and hydroponics.

Educational : 

Ideal for quick pH and conductivity checks in laboratories and schools.

Main Features :

  • Waterproof and Dustproof Housing - IP67 rated, ideal for rugged harsh conditions. Plus it floats! 
  • Multi-parameter - toggle between pH/temperature, TDS/temperature and Conductivity/temperature at touch of buttons 
  • Multi-Point Push-button Calibration (up to 5 points for pH/Conductivity) - for easy, quick calibration 
  • Auto-Buffer Recognition for pH calibration (USA or NIST) - no calibration mistakes 
  • Auto-Ranging for Conductivity/TDS measurements for fast response and best resolution over wide measurement range 
  • User-Customization for enhanced flexibility and viewing of Conductivity/TDS effective cell constants per range, electrode diagnosis - pH slope/offset/mV base value, previous calibration points, etc. 
  • Stability Indicator prompts whenever reading stabilises Auto-Hold Function automatically freezes reading when stabilized for easy viewing and recording 
  • Auto-Power Off saves battery power after non-use 
  • Self-Diagnostic with message codes for easy troubleshooting Large, 
  • Easy-to-Read Custom LCD Display with simultaneous readings provides optimum viewing with user-friendly icons 
  • Easy Interchangeability of electrodes caters for other specialty electrodes for specific applications 
  • Rugged Carrying Case (Included) provides handy on-site meter calibration and measurement
