The passive probe ENVI® is ideal for environmental testing, and measurements in climate chambers from -55°C bis +200°C.

The world's first modern probe for this high temperature range with 400V / 1250V peak input voltage range, 10:1 divider and 500MHz bandwidth is suitable for a variety of applications.
Individual contacting with high signal fidelity in different applications is ensured with the replaceable spring tip and a variety of contacting accessories.
Due to its BNC connector with divider read-out function(RO) the probe is universally connectable to any oscilloscope with 1 MΩ BNC input including automatic scaling on the oscilloscope display.
All probes are calibrated at the end of production. The factory calibration certificate is optional.
