AIR ION COUNTER

Description The model DLY-4 Air Ion Counter & Mobility Discriminator is designed for measure the concentration of ions per cubic centimeter. It can discriminates the negative and positive ion by polarity, separates the ion size by mobility.

The latest development of this instrument is the new invention of GOLD PLATED ION COLLECTOR, which makes the instrument more effective, accurate and stable. The other improvements are: the ion collector and electrometer are designed in one assembly set. We can directly read out the ion concentration from the panel LCD display.

This instrument has a build-in battery DC supply, it can work with or without the AC line support. This will be very convenient to those field-work measurement. Now, DLY-4 has become a very useful important instrument to the researchers in many scientific fields as medicine, biology, climatologic, environment, industry etc.
