pH / mV / Dissolved Oxygen / Temperature
Affordable optical RDO technology reduces maintenance time and costs
:: Maintenance free optical probe with no electrolyte eliminates hassle of replacing delicate membranes and salt build up from refillling solutions
:: Switch between pH, mV, % saturation and mg/L (ppm) dissolved oxygen – With the press of a button
:: Durable waterproof and dustproof design with IP67 rating
:: Large, backlit graphic display provides measurement with temperature
:: Calibrate up to 5 points automatically with USA or NIST buffer groups (up to 6 points with DIN). New manual option allows calibration with up to 5 custom buffer standards
:: Auto buffer recognition – Automatically identifies the correct pH buffer for rapid calibration
:: Calibration due alarm – Set a visible reminder when it is time to recalibrate the meter
:: Selectable ºC or ºF – Choose units to best fit your application
:: Ready indicator, manual or automatic measurement hold feature and optional automatic shutoff function
:: Store up to 500 data sets – Easy USB or RS232 output with optional data cables
:: Built-in real-time clock stamps stored data and calibration data with time and date – Meets standards for GLP (Good Laboratory Practices)
