Digital Static Field Meter up to ±40 kV with ToF Distance Sensor and OLED Display - Desco 19432

Insulators such as PCB base material, plastic housings or films cannot be grounded, yet their fields can induce voltages on components. The Desco 19432 Static Field Meter shows how strongly an object is charged and with which polarity. The built-in time-of-flight sensor measures the distance to the object and adjusts the value automatically, so readings no longer depend on how the meter is held.

Key benefits

• Measurement range 0 to ±40.0 kV with polarity indication.
• Time-of-flight distance sensor from 1 to 200 mm with automatic adjustment of the reading.
• Auto-zero through the dissipative enclosure when held by a grounded operator.
• Automatic snapshot hold freezes the value when the meter is moved away from the object, memory for 10 readings.
• Chopper-stabilised sensor for accurate readings in normal and ionised environments. OLED display with 160° viewing angle.

Applications

Assessing process-essential insulators at ESD workstations, locating charge sources, checking packaging and materials. With the 19433 upgrade kit also for periodic verification of ionisers.

Standards

The meter supports measurement of electrostatic fields on insulators as required by IEC 61340-5-1 for ESD protected areas.
