Evaluating Electrostatic Properties

An extensive range of instruments are available to quantify electrostatic hazards and process problems. Some of these can be used not only in the laboratory but also in plants.

Floor, Footwear & Gloves Testing Equipment
This can be used to assess the working environment, including personnel and their protective clothing. This is a weak link in the safety chain which we have found is often overlooked.

Resistivity & Conductivity Equipment
A range of laboratory instruments to determine how readily static charge can be conducted away from a material, and to indicate the likely risk of undesirable static build up. Each instrument is designed to test a different type of material, including liquids, powders, films and solids.

Charge Decay Time
Data from this instrument complement conductivity and resistivity measurements, and are especially useful in differentiating between higher resistivity materials. The likelihood of static problems arising from the use of tested materials can be determined. Apparatus is available to measure charge decay times on powders, films and solids.

Spark Incendivity Probe
The gas ignition probe enables a static discharge to be drawn from a surface through a gas mixture of known ignition energy. This is a means of estimating discharge energy in a way that is extremely demonstrative and intuitively practical.

Spark Detection Equipment
For remote detection of electrostatic sparking activity on plant using radio frequency monitoring equipment.

Humidity Controlled Work Station
Electrostatic properties are substantially affected by relative humidity, so it is often imperative to test under known and controlled environmental conditions. This work station provides a simple means of achieving controlled humidity and can be used for all the resistivity, conductivity and charge decay tests described above.
