The SV 30A type 1, two levels acoustic calibrator is the State of the Art instrument. The design of this calibrator is based on the dedicated ½" condenser microphone and microprocessor controlled signal source including digital static pressure and temperature compensation. These both features assure excellent stability of the calibration levels and their frequency. The SV 30A calibrator offer exceptional price versus performance ratio on the world market.
Infrasound Calibrator Ttype IFC-1 is designed for calibration of acoustical instruments intended to meter of low-frequency signals according to ISO 7196 :1995 "Acoustics - Frequency weighting characteristic for infrasound measurements". Measuring microphone of the tested instrument is tightly coupled to the acoustic actuator of the infrasound calibrator by a pressure chamber. Internal acoustical actuator produces a low-frequency sound pressure in the cavity.
The Larson Davis Model CAL150 is a precise microphone calibrator intended for the 3/8" diameter microphones typically used on the, SoundTrack Lxt class 2, Model 700, 710, 712, and 720 SLM/Dosimeters and the Model 705 Noise Badge. The CAL150 provides a choice of calibration sound pressure levels, 94.0 and 114.0 dB (switch selectable) at a frequency of 1 kHz.
The Larson Davis Model CAL200 is a Class 1 microphone calibrator intended for the Larson Davis 1/2" or 1/4" diameter microphones. The CAL200 provides a choice of calibration sound pressure levels, 94.0 and 114.0 dB (switch selectable) at a frequency of 1 kHz.
Infrasound Calibrator Type PF-12 with a low-frequency pressure chamber is a source of acoustic infrasound wave designed for qualify effectiveness of a half-inch measuring microphones by simoultanous comparing method.
The Precision Acoustic Calibration Workstation Model 9350C is an accurate, turnkey, automated PC-based system that features cost-effective calibration of ¼", ½" and 1" microphone cartridges (open-circuit sensitivity), microphone cartridges with preamplifiers (closed-circuit sensitivity) and microphone Frequency Response Function.
The Type 40AC is a high precision microphone for laboratory work and as a working standard microphone in calibration laboratories. It covers a frequency range from 3.15 Hz to 40 kHz. Its small size and lower sensitivity make it extremely robust and stable. The Type 40AC is capable of measuring sound levels up to 160 dB re. 20µPa.
The two scales cover the 40-80dB and 80-120dB ranges, with an accuracy of ±3.0 dB. Simple to operate; one selection dial with battery test mode and easy-to-read results. Stable, reliable operation with signal oscillator calibration and a capacitance microphone. Based on the "A" decibel frequency weighting. CE Approved. Comes with a carrying case, instructions and a 9-Volt battery.
Earthworks M23 is ideally suited for acoustical measurements sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required. Each M23 is delivered with its own calibration chart providing its individually measured open-circuit sensitivity and the frequency response curve.
