19443 Ionisation Kit

The Desco 19443 Air Ionization Test Kit includes and utilizes the DESCO 19442 Digital Static Field Meter to measure the offset voltage (balance) and charge decay of ionization equipment. The Air Ionization Test Kit also includes a charger used to place a ±1000V charge on the conductive plate, making it possible to also measure the discharge times of air ionization equipment per ANSI/ ESD SP3.3 Periodic Verification of Air Ionizers. The Desco 19442 Digital Static Field Meter indicates surface voltage and polarity on objects. The meter has a measurement range of 0 to ±19.99 kV at a distance of 1 inch and a measurement accuracy of ±5%. It utilizes a chopper-stablized sensor for use in both normal and ionized environments. The meter’s enclosure is dissipative and features a 7 mm snap and ground cord for bonding to equipment ground. A rotary zero knob sets the zero-reference point with finely tuned precision, and a Hold button allows the user to “freeze” a displayed measurement for evaluation. A LED range indicator assists with placing the meter at the correct distance from the object being measured. DESCO 19442 Digital Static Field Meter Pointing the Digital Static Field Meter to a grounded surface DESCO 19443 Air Ionization Test Kit Performing Offset Voltage (Balance) Measurements The Air Ionization Test Kit has been designed to match the compact size and hand held convenience of the Digital Static Field Meter. Use the following procedure to verify the offset voltage (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 offset voltage (balance) and discharge times. An ionizer operating in an out-of-balance state can place a charge on sensitive electronic components or assemblies.
