User-Serviceable Photometers 8177
The model 8177 photometer is a retrofit option for any 8130 filter tester. Light scatter photometers are the preferred choice for detectors in respiratory filter and filter media testing. Photometers have a very high dynamic range and sensitivity and thus can be used to measure filter efficiencies up to 99.999% without dilution. The model 8177 photometers are now user- and field-serviceable, enabling the user to schedule preemptive maintenance with the least impact to production and testing schedules.
