Description
Features at-a-glance
- Built-in temperature sensor for Automatic Temperature Compensated measurements.
- Renewable junction to clear any clogging that causes readings to drift and be erratic.
- Stability indicator that disappears once a stable reading is obtained.
- Automatic calibration to one or two points at a push of a button.
- Uses Hanna’s Quick Cal pH/EC standard with a pH value of 6.86. The standard can also be used to calibrate conductivity meters to 5,000 μS/cm.
- Battery % level remaining displayed at startup.
- The low battery indicator is displayed when less than 10% battery life is remaining.
