Test Kit
Description
The Desco Portable Ionization Test Kit allows the 19445 Digital
Fieldmeter to be used to monitor the balance of ionization
equipment. The test kit also includes a Charger used to place a
1000V charge on the isolated adapter plate assembly, making it
possible to also measure the neutralization performance of air
ionization equipment. The 19447 Test Kit was designed to be used
in conjunction with the 19445 Digital Fieldmeter, providing a highly
portable and cost effective means of verifying the performance of
a wide variety of ionization equipment.
NOTE: The 19447 Digital Fieldmeter is designed to operate only
with the 19447 Portable Ionization Test Kit. It is not compatible
with other brands.
Currently there are no established standards describing a periodic
verification device or procedure for air ionizers. The Desco
Portable Ionization Test Kit has been designed to make
measurements that correspond to those made by using a charged
plate analyzer and ESD Association's Standard 3.1. While the
Ionization Test Kit provides convenience and portability, it does not
meet all of the requirements of the ESD Association Standard. We
recommend our Charged Plate Analyzer if precise measurements
are required.
The Portable Ionization Test Kit includes a slide-on isolated plate
assembly, a ±1000 volt charging unit and a durable thermoplastic
carrying case with custom cut-outs for all of the above
components along with the model 19445 fieldmeter. The 19445
digital fieldmeter is sold separately.
Inspection

Taking Balance Measurements
The Portable Ionization Test Kit has been designed to match the
compact size and hand held convenience of the 19445 Digital
Field Meter. Use the following procedure to verify the balance of
air ionization equipment. This quick and easy procedure will help
determine if the piece of ionization equipment is working within the
manufacturer's specifications or user requirements. It is extremely
important that ionizers be checked regularly for balance. An
ionizer operating in an out-of-balance state can damage
sensitive electronic componets or assemblies.

Digital Fieldmeter
1. INSTALLING THE ISOLATED PLATE ASSEMBLY - The case
of the Model 19445 Fieldmeter has two slots along its slides. The
top slot is closest to the front of the instrument. Slide the tabs of
the adapter Plate ground plate into the top slot of the meter case
as far as they go.
