When a Conductivity probe is connected: Approx. 500 hours
When an optical DO probe is connected: Approx. 60 hours
Power consumption 0.2 VA (with battery 3V), 0.9 VA (with USB-powered)
Dimension (projections not included) Approx. 70 x 35 x 185 mm

It is effective for simplified monitoring in a short time (about half a day), etc.
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).
