Non-Contact Voltage Testers
-
PeakTech Prüf- und Messtechnik GmbH
User-friendly tester for non-contact voltage testing from 50 V to 1000 V AC. Suitable for outlets, lamp sockets or against wire insulation testing. If AC voltage is present at the relevant measuring point, this is indicated visually by a flashing red LED and the integrated buzzer sounds. If the measuring point is voltage-free, the test probe lights up permanently green.

Sound Level Calibrators
-
PeakTech Prüf- und Messtechnik GmbH
For sound level measurements in extreme conditions, at high altitudes or high demands on the accuracy of the measurement results, sound level meters should be checked prior to the measurement with a sound level calibrator. Also for calibration and verification of microphones in audio technology, you need a sound level calibrator, which is designed to produce several sound pressure levels at a fixed frequency characteristic. This calibrator has two switchable calibration steps.

Omnidirectional Source
BAS001
-
The BAS001 Source is designed to generate omnidirectional sound fields for making standard compliant measurements including: reverberation time (ISO 3382, ASTM E2235), building acoustics (insertion loss, acoustic absorption area, etc: ISO 140-4 ISO 140-3, ASTM E336, ASTM E90, DIN 55 210). The BAS001 is typically used to saturate a room with a uniform acoustic field. The available high-efficiency power amplifier has no fan for cooling, allowing measurements in quiet environments, like those in reverberation time applications.
