Checker® Plus pH meter accuracy of ±0.2 pH

Checker Plus HI98100

Checker Plus is a complete pH meter at an affordable price, designed with many functions, including: automatic calibration, recognition of calibration standard solutions and digital screen for reading analysis and much more!

Key features:

• Large display: The display shows the measurement, stability indicator, low battery indicator and calibration points.
• Replaceable pH electrode: The HI1271 gel-filled pH electrode supplied with the instrument shrinks towards the end to a diameter of 8 mm. This thin electrode fits into cuvettes, vials and other containers with a narrow opening.
• Automatic calibration: Checker Plus can be automatically calibrated at one or two points. Standard solutions are recognised automatically and after calibration the buffer values are shown on the display.
• Stability indicator: An hourglass appears on the display until a stable measurement is obtained. Once stable, the indicator disappears and the measurement can be recorded.
• Automatic switch-off: The instrument is equipped with an automatic switch-off function, selectable after 8 minutes or 60 minutes of non-use, to save battery power if the instrument is left on. This function can be switched off.
• Long-life battery: Checker Plus has a battery that lasts for about 1000 hours. When it is low, a low battery indicator appears on the display.
