Calibration of the pH probe is easy, instructions are included with the device and you only need to calibrate using one button. The pH probe is replaceable, there is no need to buy a new device.
The temperature and EC probe does not require calibration, it is preset at the factory. The combined meter Bluelab Combo Meter comes with 2xAAA batteries. Automatic shut-off when idle is a matter of course. The device has a five-year warranty for defects not caused by mishandling. The probes have only a six-month warranty.
