Upgrades for Noise Dosimeters
Various upgrades to improve and enhance the performance of noise dosimeters are available as required. CEL-35X series dosimeters can be upgraded between all model to add the additional benefits of time history data logging in the CEL-350 and 352 models or the LCeq and the L(C-A) results in the CEL-352 Plus model. A basic CEL-320 can be upgraded to the full CEL-360 model to add time history recording plus delay start/stop timers plus the fixed run duration modes if required. Units should be returned to Casella CEL in NH to have the upgrades performed in our service laboratory often as part of the annual recalibration.
