2400 Sound Level Meter
The large LCD display provides up-to-the-second readings in 0.1dB increments as well as indicating a low battery (LOBAT) condition. And the slide switches make the meters extremely easy to operate - even while wearing gloves.

2900 Integrating Datalogging Sound Level Meter
The Quest 2900 (Type 2) Integrating/datalogging Sound Level Meters enable the use of one instrument to analyze "A", "C" or Linear weighted sound levels using a choice of exchange rates. With the use of 1/3 or 1/1 octave band studies, integrating all the information together in one file is easy. Create and store multiple files without having to print or download the instrument. The information will stay in memory, even if the instrument is turned off or the batteries taken out. The hand-held 2900 is ideal for compliance, noise control analysis, traffic studies, worker exposure profiles and most any industrial or community noise measurements.

208 Pocket Size Sound Level Meter
Quest's Model 208 Sound Level Meter is a small, cost-efficient, sound level meter for basic measurements. Measure sound level in a "A" weighted slow response mode as required by OSHA and other noise regulations. Weighing a mere four ounces, the meter is housed in a high-impact plastic case. It is powered by a single 9-volt battery. Battery life is 70 hours of continuous use.

Q-100 Noise Dosimeter
The Q-100 Noise Dosimeter is a compact, rugged Type 2 sound level meter and datalogging dosimeter which is perfect for the budget-conscious user requiring general purpose noise measurements. Preset and ready to use for typical noise measurement applications, the versatile Q-100 can also be reprogrammed with an IBM-compatible computer to accommodate specialty applications.

Q-200 Noise Dosimeter
When measurement flexibility is a must, but time histories and printouts are not, the Q-200 provides a cost effective solution. The display and keypad functions allow access to important information and user set-up of a broad range of functions. The Q-200 is designed for applications including industrial, mining, military and law enforcement.

Q-300 Noise Dosimeter
The Q-300 Noise Dosimeter is a highly versatile, multi-function datalogging noise dosimeter. It performs a wide variety of acoustical measurements for applications such as workplace evaluations, personal exposures, compliance assessments and environmental analysis. RF shielding and intrinsically safe design means the Q-300 can go where you need it. While the Q-300 is easy to use, it provides the details and flexibility required by industrial hygiene, safety and environmental professionals. The unit will calculate, display and store Sound Pressure Levels, Max and Min Levels, Peak Levels, Averages, Time Weighted Averages, Sound Exposure Levels, Dose and Projected Dose, and Exposure in Pascal squared hours.

2800 Impulse Integrating Sound Level Meter
Quest's Model 2800 is a rugged Type 2 integrating sound level meter which provides comprehensive data for occupational and environmental noise measurements. The meter can display and print sound level, integrated sound level, max level, min level, SEL, peak, and impulse readings. The Quest 2800 outputs directly to most any serial printer to provide a detailed report.

QC-1/QC-20 Sound Level Calibrators
To ensure the accuracy of your sound measuring instrumentation, Quest Models QC-10 and QC-20 Calibrators provide quick, precise calibration. The Model QC-10 is a general purpose calibrator that generates a constant sound pressure level of 114dB at a fixed frequency of 1,000 Hz. Model QC-20 is recommended for use with precision ANSI and IEC Type 1 instruments. Four different outputs may be generated by selecting 94 or 114dB and 250 or 1,000 Hz frequencies for verifying weighting filters and -20dB attenuators. Both the QC-10 and QC-20 models have a standard one-inch coupler opening that may be reduced by utilizing available snap-in adapters.
