Handheld 2-D EM current meter with temperature and depth sensor AEM213-D

AEM213-D
■Description
AEM213-D electro-magnetic current meter with a display unit can provide the 2-D current speeds in real time. The instrument has a depth and a temperature sensor as well as the current sensor, enabling reliable current measurements at the desired depths. The compact and light-weight unit is easily portable, allowing you to use the instrument in a variety of situations.

AEM213-D has a display unit with a flash memory. The observed data are shown in the display and then saved in the memory simultaneously. The data can be easily downloaded from the unit to a personal computer using a communication cable. The battery is a size C alkaline battery, allowing surveys for up to 10 hours.
