The model 288B is the first charged-plate monitor offering on-board data storage to automate ionization system testing. Use the Model 288B to perform the customary manual tests, or program it to perform a series of automated decay and balance tests.

Soft keys simplify the programming and operation of automated tests. Upload test set-ups and ionizer locations. Download stored test results, including environmental data captured by integral temperature and relative humidity sensors. The Model 288B uses a novel voltage-follower measurement technique to increase stability, bandwidth, and accuracy, making it ideal for testing the most modern critical-balance ionizers.
