เครื่องวัดความเป็นกรด-ด่าง/การนำไฟฟ้า/ของแข็งละลายน้ำ แบบพกพาสะดวก ช่วงสูง รุ่น HI98130

HI 98130 simultaneously measures pH, conductivity, TDS and temperature. It is easy to use, fast and accurate, and is therefore ideally suited for routine measurements. With replaceable pH electrode.

• Dual display of pH or conductivity / TDS and temperature
• Easily replaceable pH electrode
• Rugged graphite conductivity probe
• Automatic calibration and temperature compensation
• Selectable TDS factor and temperature coefficient
• Stability indicator of safe values
• HOLD function to freeze a reading in the display
• Battery charge indicator and automatic shut-off

Ordering Information : incl tester pH electrode, electrode replacement tool and batteries.
