The LCD Touchscreen Portable PH / Temperature / ORP / Ion Muti-parameter Lab pH/Ion Meter Kit E60 provides accurate, real-time measurements of pH, ORP, temperature and ion concentration. It is perfect for lab use and comes with a clear LCD display that allows easy monitoring and readings of all parameters. The meter is lightweight and portable, making it ideal for in-field testing. Features: Color High contrast LCD touchscreen, 4.3 inches. Multi-reading feature allows auto-read, timed-read and continuous-read. Automatic/Manual temperature compensation ensures accurate results. Auto-hold feature senses and locks the measurement endpoint. Data capacity of up to 500 sets for each parameter (GLP-compliant). Support for USB communication. Auto-power off feature effectively extends the battery service life. Reset feature automatically resumes all settings back to factory default options. IP65 waterproof. The portable meter is suitable for fields measurements and out door measurements. pH 1-5 points calibration with Standard Recognition. pH Selectable pH buffer groups, including NIST, DIN, GB, USA. pH Automatic electrode diagnosis with pH slope and offset display.
