DP-30 is a patent product to fill the blank of domestic market developed by Suzhou Norda, used for the
leak detection of integrity filtration system.
Summary
DP-30 Aerosol Photometer is a kind of special test instrument to test the leakage of HEPA, designed on
the base of light scattering principle, displays real-time leakage rate by detecting aerosol concentrations
of upstream and downstream. Applicable for testing clean rooms, laminar flow benches, bio-safety
cabinets, glove boxes, HEPA vacuum cleaners, HVAC systems, HEPA filters, ULPA filters, negative
pressure filtration units, surgical suites, nuclear filter banks, collective protection filters, etc.
Features
User friendly interface
3.5” LCD display, menu driven interface. Aerosol measurements, real time concentration and pump sampling rates
are prominently displayed for easy viewing. System parameters and selections such as alarm types, alarm set points
and aerosol reagent are shown on the lower menu bar, while icons at the top of the screen give the status of
connection, alarm type, reporting mode.
Portable scan probe
The Probe acts as an extension of the base instrument through a nearly identical user interface. All status and
selection icons from the base unit are represented on 2.8” LCD, which can improve work efficiency and give
immediate presentation when find leakage.
Easy to trace measurement result
DP-30 has three independent reporting functions storage/continuous/print modes, the result can be printed out by a
thermal printer.
Performance guaranteed
DP-30 adopts import pump (Britain), import light source (Japan) and the sensor produced with top domestic
precision process technology (same as the domestic aerospace technical standard), and has been independently
tested and qualified to ensure compliance with all applicable electrical and safety requirements.
Complete and quick after-sales service
As an independent domestic developed photometer, DP-30 has low cost and quick response (within 2 hours by telephone) after-sales service; free charge for software updating; prototype instrument is available.
