The SONUS Pocket Dosemeters are designed to be powerful and easy to use. These dosemeters are small and tough so measurements and data can be collected throughout the working period. Data can be reviewed on screen or downloaded to a PC for further analysis.
There are 2 different SONUS Dosemeter models:
The SONUS GA257B is a dedicated basic dosemeter fully compliant with IEC 61252:1993, giving simultaneous sound exposure (Lepd) and maximum peak (Zpeak) measurements, an essential feature for Noise at Work Regulations assessments.
The SONUS GA257L adds logging capabilities, allowing data to be downloaded to a PC using the Castle dBdataPro noise analysis software, and measures sound pressure levels and Leq.
The GA257 noise dosemeters are easy to use and have a clear display allowing data to be read on screen. The keypad can be locked to prevent any measurements being accidentally stopped or altered. The data is stored on flash memory at user selected intervals. The built in software for this meter is designed to suit future upgrading for feature enhancements, legislative changes or instrument upgrades. With the Castle SONUS Dosemeters you will always be in step with the law.
Parameters measured (both GA257B and GA257L):
User selectable Exchange Rate (3dB, 4dB or 5dB) User selectable Criterion Level (75dB, 80dB, 85dB or 90dB) User selectable Threshold Level (-5dB, -10dB or OFF) Pmax % Dose Projected % Dose Lepd (Lex) % DOHR (Dose/Hour) Pa2h (Lepd expressed in Pascals) Exposure Calculations Linearity Range 30-140dB Lockable Keypad Constructed from tough crack resistance plastic
The GA257L dosemeter also features:
Lp (SPL) Leq Real Time Clock Data-Logging, up to 4800 intervals at user selected periods Output to PC for further data analysis DC Power In AC Output
Each GA257 SONUS Dosemeter is supplied in its own plastic case complete with a handbook, windshield, calibration screwdriver and pen.
