EUTECH PD450 Portable PH DO and Temperature Meter

PH METER


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)
