The 2900 provides General Purpose Type 2 accuracy. Each meter incorporates an internal datalogger allowing you to store one or multiples of sound studies in the field for later printing or downloading to a computer.

Optionally, a second RMS circuit simultaneously measures both "C" and "A" weighted SPL, calculates the difference and provides the result for display or printout.

The Noise Pro DLX provides even more data per time history interval, intervals as fine as one second in duration and a host of additional programmable features.

The Noise Pro DLX has many programmable settings to serve a variety of applications. Settings can be auto-configured to meet specific regulatory standards by simply selecting the standard's name from a list of pre-defined setups.

User-specified setups may also be defined and deployed. Multiple virtual dosimeters in each instrument permit assessments against more than one standard simultaneously. A large, backlit, graphical display shows measured and calculated parameters in an easy-to-understand format.

The microprocessor based M-28 Noise Logging Dosimeter can be used as a personal noise dosimeter, an area monitor, and as a noise survey instrument. As a community or airport monitor, it can monitor average; peak or maximum levels as often as every 10 seconds as well as calculate exceedance and day/night levels. As an occupational noise monitor, it can calculate noise dose with selectable exchange rates, criterion levels, and thresholds. Exposure is calculated in percent dose and Pascal squared hours.
The M-28 monitors noise exposure, as well as sound, peak, and maximum levels, and run, pause, upper limit, and real or elapsed times. It also stores, displays, and prints out data for 16 different events. Can be downloaded to a serial or parallel printer.

The db-3100 combines a universal noise dosimeter, an integrating/averaging and true peak sound level meter and a time history monitor into one small, easy to operate instrument. Housed in a rugged, lightweight, water-tight aluminum extrusion, the db-3100 can withstand environmental and industrial usage. Three pushbuttons control all logger functions. The db-3100 comes preprogrammed for common test conditions.

Programming changes can be accomplished by using the ms-3100 software and a PC. In addition, complete reports can be output directly from the db-3100 to a computer. The MS 3100 software is an enhanced software package that allows you to program the db-3100, perform data retrieval, create graphs & reports, perform projection studies.

Use the OB-100 octave band filter set with Quest sound level meters, models 1800 or 2800 to measure selected frequencies and obtain detailed analysis of hazardous or uncomfortable noise sources. Model OB-100 features 10 ranges with centre frequencies from 31 Hz to 16 kHz in full octave bands. The unit offers automatic or manual operating modes. In manual mode, choose a single octave for individual measurement. Use auto mode to step sequentially through each band. Use the OB-50 with the Quest 2700 SLM.
The OB-50 provides nine octave bands from 31.5 Hz to 8 kHz.

The Quest Model 1800 is a precision, type 1 impulse and integrating sound level meter. This instrument is easy to use with a large LCD which provides digital as well as bar-graph display of sound readings. The Model 1800 is housed in a tough, injection molded case with internal shielding. The various functions of the instrument are accessible through convenient slide switches and push buttons. Data collected during the “RUN” mode is produced in a pre-formatted report that can be downloaded to a serial printer.
Range: 20dB to 140 dB.

Quest's Model 2800 is a rugged Type 2 integrating sound level meter which provides comprehensive data for occupational and environmental noise measurements in even the most harsh applications.

Although the 2800 can perform sophisticated measurements, it is easy to set up and operate. The meter can display and print sound level, integrated sound level, max level, min level, SEL, peak, and impulse readings. The clear, easy-to-read digital display is complemented with a unique quasi-analog bar graph.

The Quest 2800 outputs directly to almost any serial printer to provide exceedance level chart. When used with the Quest Ocatave Band Filter Sets, the 2800 also prints each octave or 1/3 octave band reading from memory storage.

The Quest 2700 Impulse Sound Level Meters is a general purpose instruments designed for sound pressure level measurements with or without the use of optional bandpass filters. The Q 2700 provides Type 2 accuracy for general survey work. Applications include laboratory, industrial, community and audiometric measurement and analysis. The Model 2700 is a user-friendly hand held meter with an LCD display that provides a numerical and bar graph readout. The meter is operated with easy-to-use slide switches and push buttons. The range of the Model 2700 is switchable between the following: 20-80 dB, 40-100 dB, 60-120 dB, or 80-140 dB.

The Quest 2400 Type 2 Sound Level Meter is ideal for spot checks and basic noise surveys. Suitable for analysis of laboratory, industrial, community, military and audiometric measurements. Features: • Linear and A weighted readings. • Peak hold. • Fast, slow and impulse settings. The 2400 is a hand held meter with an LCD display that provides a numerical readout. Range : 30 to 140 dB.
