Features | Benefits |
| Microprocessor Controlled | Quickly sets operator functions and parameters, easily programmed and operates with just 7 push buttons |
| Digital display with set-up menu and diagnostic codes | Very simple ease of use for operator |
| Range of concentrations measurable from 100 to 0.0001 μg/l | Allows testing of many different classes of HEPA and ULPA filters |
| Storage of sampled concentration as reference value | Instrument can be transferred to a downstream location for testing far removed from the point of the upsteam challenge location without losing the upstream challenge data |
| The 2H can be calibrated to two different oil types (normally Shell Ondina and PAO) | If the instrument is to be used within different organisations at varied locations, instrument requires no recalibration for testing a different oil to the standard one |
| Compact and die cast aluminium design with swivelling handle | Light and rugged; handle acts as a support, allowing tilting of the control panel display for easy viewing |
| Power 1-250 AC, 50/60 Hz | Can be used with majority of mains power sources |
| Auto-Ranging; automatic from 0.0001% to 100.0% | Provides 6 decades of display and eliminates the manual range selection switch |
| Leakage Isolation Test | Leaks normally invisible to the naked eye are easily isolated so that repair/replacement decisions can be made |
| Auto Zero | Automatically establishes zero by pressing the 0% button when sampling the airflow through the iunternal ULPA reference filter in the clear mode. Automatically establishes downstream reading as zero by pressing the 0% button when sampling the downstream airflow. |
| Bar Graph | Solid-state bar graph with high visibility green LED on control panel and scanning probe |
| Solid-state linear amplifier | S |
| Digital Display | Shows % Leakage from 0.0001% to 100.0% |
| Dynamic Range | 0.0001 to 125 μg/l. Improved firmware prevents system errors by blanking the display when sampling above 125 micrograms per liter; display is restored when concentration is lowered. "HIGH" mode enables sampling of concentrations exceeding 200 micrograms per liter. |
| Long lasting, stable, solid-state scattering chamber light source | Photometer operates at low power, generating low heat, and low stray light values. Life expectancy is 50,000 to 100,000 hours. |
| Repeatability | The 2H has been tested to verify repeatibilty within 0.05% |
| Scattering Chamber | Field-tested design for efficient and reliable performance. A three-stage “OPTICS” indicator ensures accurate internal reference response; green indicates internal reference within 5% of original value, orange indicates internal reference shifted to 5-10% of original value, and red indicates that the internal reference has shifted by more than 10%. |
| Vacuum Pump | True 1 cubic foot per minute (cfm) sample rate (28.3 liters per minute) using a twin head, carbon vane pump for quiet operation and dependability. A HEPA filter is externally integrated at the outlet of the vacuum pump entrapping any particles from the pump exhaust. A “FLOW” indicator ensures operation within required parameters. |
| Output | A DB9 connector is provided standard on all units for RS232 output. |
