产品概述与应用
pH / mV / Dissolved Oxygen / Temperature Affordable optical RDO technology reduces maintenance time and costs
Maintenance-Free Optical Probe - Maintenance free optical probe with no electrolyte eliminates hassle of replacing delicate membranes and salt build up from refillling solutions
Multi-Parameter - Switch between pH, mV, % saturation and mg/L (ppm) dissolved oxygen – With the press of a button
Waterproof Design - Durable waterproof and dustproof design with IP67 rating
Large Display - Large, backlit graphic display provides measurement with temperature
Flexible Calibration - 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 Alarm - Set a visible reminder when it is time to recalibrate the meter
Temperature Units - Selectable ºC or ºF – Choose units to best fit your application
Measurement Features - Ready indicator, manual or automatic measurement hold feature and optional automatic shutoff function
Data Storage - Store up to 500 data sets – Easy USB or RS232 output with optional data cables
GLP Compliant - Built-in real-time clock stamps stored data and calibration data with time and date
