Oakton® pH 310 Portable pH Meters, Waterproof

The microprocessor-based OAKTON® waterproof 310 portable ph meter reads pH - mV or relative mV and temperature in °C and °F (selectable).The built-in real-time clock stamps stored readings and calibration data with date and time - which lets you meet standards for Good Laboratory Practice (GLP). SETUP mode lets you customize meter parameters. Specifications:
