Battery life (estimate)
*Backlight turns off, option not connected

When a pH or ORP probe is connected: Approx. 800 hours

*¹ It is effective for simplified monitoring in a short time (about half a day), etc.
*² The use of AC-USB adapter ASSY (7472510K) is recommended for optional analogue-output connections and for continuous-measurement with DO probes because battery life is shortened (USB-powered).
