Benchtop Ion Meter - Laboratory pH and ISE Meter with LCD - -2.000 to 20.000 pH - 7-Point ISE

The Master Science Benchtop Ion Meter is a button-operated pH and ion meter with a 7-inch high-resolution LCD. It measures pH from -2.000 to 20.000 with ±0.002 pH accuracy, ion concentration by ion-selective electrode, mV and temperature.

pH takes up to five calibration points and ions up to seven. More than ten ion methods are stored, including fluoride, chloride, nitrate, ammonium, potassium, sodium, calcium and ammonia nitrogen, and four measuring modes are available for difficult samples.

Common Problems and How This Meter Helps

How the Master Science Benchtop Ion Meter supports routine ion analysis:

• Two instruments for pH and ions: one meter measures both.
• Interfering sample matrix: standard addition, sample addition and GRAN modes.
• Readings taken before stabilising: auto-hold and locked prompt.
• Hand-written logs: 500-result memory with PC and printer output.
