Noise Dosimeters/Datalogging Dosimeters Q200 is a powerful dosimeter used for display-only applications Q300 is a highly versatile, multi-function datalogging dosimeter Q400 is a full featured, advanced datalogging dosimeter NIST it S Sound Level 1154 Model Q200 • Easy-to-Read Display • Simple Operation • Battery Changes are a snap •Instructions where you need them • Security to protect your work Two levels are provided to lock out set-up charges or all display functions. Accidental turn-off or reset are also prevented by five second function count down •Tough, Compact Case Cast aluminum housing provides durability, tested RF protection and intrinsic safety Model Q300 •Instructions where you want them • Log all the information you need including sound levels and peaks • Meet all the requirements Three simultaneous dosimeter studies using independent threshold, criteria and exchange rate assures you will have what you need today and tomorrow • The power to do the right job • Long battery life • See it now, print it later • The LCD display lets you see what you want now, and parallel/serial output allows direct printing of all the details • Security •Run it even if you are not there •Auto on/off and auto run time •Paperless surveys • The unique event function makes surveying a variety of locations easy. Just keep track of where you went, and the Q-300 will do the rest, keeping information separated so you can analyze each location at your convenience Model Q400 • Two true independent analog circuits • Simultaneous “A” and “C” measurements—allows for “C” minus “A” calculations • Field Selectable - Projected dose periods, Threshold levels, Upper limit levels, Exchange rates, Criterion levels • Real time clock with automatic start/stop • Up to 999 (or 100 hours) stored events • Pre and post calibrations on printout SPECIFICATIONS Models Q200 & Q300 Standards ANSI S1.25-991, ANSI S1.4-1983: Type 2; IEC 651-1979, IEC 804-1985: Type 2; IEC 1252-1993 Measuring Range Detector Data Output (Q300 only) Microphone Battery Temperature Humidity Electromagnetic Field Effects Model Q400 Standards Operating Range Dynamic Range Exchange Rates Criterion Levels Display Output Size/Weight Davis Inotek Instruments 40-110dB or 70-140dB True RMS, 63 dB Pulse Range Uses interface modules connected to the microphone connector.

Convertible Noise Dosimeter/Sound Level Meter NIST it The CEL-300 Series "Convertible" dosimeters and sound level meters offer the ability to make noise measurements in many different environments. The units are called "Convertible" because the user can turn a dosimeter into a sound level meter and back again, simply by inserting a different microphone. This provides the most flexibility in a single unit and reduces the cost for the user. In dosimeter mode, instruments are delivered pre-programmed with the operating parameters to measure noise dose to the relevant standards (ie OSHA), and measure from 30 to 140 dB in three 70 dB ranges. Whilst the CEL-320 provides summary statistics for download, the CEL-360 stores individual readings to provide a full time history. In sound level meter mode, instruments possess up to 20 configurable operating modes, which can be user programmed to suit any specific task. Simply selecting the mode and pressing "run" starts the measurement and displays current information. Download all the data to the PC for subsequent analysis. Both models are suitable for workplace noise monitoring, simple hand-held noise surveys and long term boundary monitoring. They are rugged, lightweight, easy to use and conform to both ANSI and IEC standards.
