Kasuga Digital Low Potential Measuring Device

 The KSD-3000 measures electrostatic charges of 100V or less with high precision, and measurements starting from 0.1V, which are difficult to measure with conventional models. This devices also allows measurement of narrow areas such as the surface of an LSI package.

• It can measure low-potential static electricity that causes static electricity damage.
• Has a range switching function to measure minute potentials.
• By shortening the measurement distance, the measurement area can be narrowed down, making it possible to measure an area approximately 20mm square, making it possible to measure the surface potential of small electronic devices with high precision.
• The display section and detection section are separate, allowing you to measure in tight spaces and view the measured values ​​at hand.
• It is possible to measure not only small electronic components but also potential distribution of wide objects.
• You can switch between peak hold measurement and continuous measurement.
• It has a built-in detection sensor failure diagnosis circuit that will display an indication when a failure occurs. (patent)
• It comes with a sleep mode function to prevent battery consumption if you forget to turn off the power

Kasuga Explosion Proof Digital Electrostatic Potential Measuring Device

• The case of the measuring instrument is coated with conductive paint to ensure safe and accurate measurements.
• This is a small, handheld measuring instrument with a digital display that can be easily used even in tight spaces at production sites.
• Measurement range: ±0.1 to 19.9KV
• Japan and China bomb defense certification certified

Kasuga Human Body Potential Measuring Device

This device accurately measures the potential of the human body, and it can be immediately determined whether electronic devices will be damaged by this potential. You can also learn how much static electricity countermeasures such as conductive floors, static mats, static shoes, and wrist straps reduce human body potential.

• By holding the probe in your hand, you can easily measure the charged potential of the human body.
• Achieved high resolution of ±0.1V. (KSD-4000)
• Can measure over a wide range.
• You can switch between peak hold measurement and continuous measurement.
• By using a recorder together, it is possible to continuously record changes in the human body potential during each movement of the worker.
• Easily evaluate and educate workers on static electricity countermeasures.
• It has a built-in detection sensor failure diagnosis circuit that will display an indication when a failure occurs. (patent)
• It comes with a sleep mode function to prevent battery consumption if you forget to turn off the power.

Kasuga Air Ion Monitor

Atmospheric ion monitors measure the potential of a charged plate (detection part) with high precision, which has a capacitance that is almost the same as the ground capacitance of the device, and are ideal for checking the effectiveness of ionizer installation and daily management.

• Built-in high voltage power supply allows you to easily evaluate and manage the ionizer with a single button.
• Since the small detection probe is separate, measurements can be taken in confined spaces, such as when evaluating ionizers installed in manufacturing equipment, and the display can be viewed at hand.
• Evaluation can be performed using the same size and capacitance as the device.
• The compact and handy type of main unit makes it very convenient to carry to the work area.
• Ion balance can be evaluated and managed with high resolution of ±0.1V.

Kasuga Coulomb Meter

Many ESD phenomena that cause damage to electronic devices are represented by the CDM (Charged Device Model). CDM is a model that describes the phenomenon of fast, high peak currents flowing when the device itself is charged and its external electrode is grounded. This coulomb meter measures the amount of discharged charge, which is the integral value of that current, with high precision.

• The amount of discharged charge can be easily measured by simply touching the object to be measured (conductor).
• The amount of discharged charge due to inductive charging of electronic devices and printed circuit boards surrounded by charged insulators can be measured.
• This measurement method is tailored to actual electrostatic breakdown phenomena (CDM).
• Since it is a contact type, there are almost no measurement errors due to differences in the measurement person.
• You can switch between two modes: peak hold and continuous measurement.
• A conductive probe tip is available as an option, so you can safely measure sensitive products.
• An AC adapter is available as an option, making it convenient for long-term use in evaluations, experiments, etc.
• By using the separately sold ZHO-202PN, device capacitance can be converted.
• By using the KQ-1400 (sold separately), it is also possible to measure electrostatic charge (Faraday cage method).

Kasuga Electrostatic Potential Monitor SP-WATCH

SP-WATCH®KSD-0110 is an electrostatic potential monitoring device that has an interface to connect our potential sensors EMS-01/EMS-01A/KS-2100 and measures static electricity in real time.

• Up to 2 channels of potential sensors can be connected, and both channels can display measured values ​​in real time and record data.
• Full color LCD touch panel with good visibility, making it easy to recognize the current situation and allowing intuitive operation.
• SD card compatibility allows measurement data to be recorded and processed on a computer.
• Each channel can have two levels of alarm settings and can output control to the outside.
• The combination of potential sensor EMS-01/EMS-01A and safety barrier KS-301A can be used in hazardous locations (explosion-proof areas).
• EMS-01A (air purge sensor) applies internal pressure inside the sensor by supplying air, making it difficult for powder and paint mist to enter the potential sensor, making it highly durable and suitable for use in environments where static electricity could not be measured until now. Static electricity can be measured and monitored.
• When using the potential sensor KS-2100/KS-3101, if the potential sensor fails, it will be immediately displayed on the screen.
• Can be used with the vacuum environment compatible potential sensor KS-3101.
• The display languages availabe are Japanese, English, and Chinese, making it suitable for international use.
