12 channel parallel (This is availalble for U-52G, U-53G.)

Note:
*Battery life based on continuous operation using alkaline C dry batteries when the monitor temperature is over 20℃ and the backlight OFF.
*Accuracy is measured by calibrating 4 points for turbidity and electrical conductivity and 2 points for all other measurements against standard solution.
*Repeatability is measured by the ability to reproduce the results against the standard solution (at 25℃ normal pressure condition).
