Product Details

  • Negative ion Measuring instrument EB-17

  • Negative ion Measuring instrument EB-17

Simple operation: By just turning on the switch, measurement will be completed in 10 seconds, assuring accuracy for anybody. Easy-to-read display: Numeric display of results.
Stable measurement results: Unlike conventional air ion counters, our counter always ensures accurate results. Small in size: Easy to carry as a sales tool.

Negative ions released mainly from natural ores and ceramics can be counted. Low dose radiation, released from natural ores and ceramics, reacts with water in the atmosphere, when negative ions are generated. EB-17 detects the released small amounts of radiation, whose data is processed by a computer to obtain the number of negative ions (per cm3).
The result will then be displayed.


■ Power: 4 AA alkali battery ( lasts 60 hrs)
■ Size: 167 x 73 x 40 ( L x W x H)
■ Weight: 330 g ( excluding batteries)
■ Guarantee valid only in Japan

EB-17 can also measure negative ions released from fabric made from ceramics as well as rubber and plastic products. With its easy operation, EB-17 will serve as a useful tool in developing new products. The device will help select appropriate materials, confirm the amount of negative ions used, identify products, perform quality control, and promote sales of newly developed products.

We have concluded that 100/cm3 would be appropriate to obtain favorable effects for sheets and other products that are used in contact with our body for long hours. (Excessive negative ions will sometimes make you feel drained like after taking a long hot bath.)


EB-17 is only suitable for detecting the generation of negative ions (caused by small amounts of radiation) under static condition at normal temperatures. Please be aware that some natural ores such as tourmaline do not generate negative ions under static condition at normal temperatures but generate them only for a short period of time (3-5 seconds) only under certain conditions such as addition of a strong shock and pressure.
