英文详细介绍：
Description
The 2H is the latest digital photometer available in a portable self-contained unit. The 2H has been designed with the user in mind for simplicity of operation ａnd virtually maintenance-free use. Its basic purpose is to detect ａnd measure mass concentration of aerosol. Three-stage airflow sensor ａnd optics indicator lights improve data reliability.
The microprocessor-controlled 2H enables the operator to quickly set operating functions ａnd parameters. It is easily programmed ａnd operates with just 7 push buttons. The digital display has a set-up menu ａnd diagnostic codes for operator convenience. The range of concentration measurable is from 100 to 0.0001 µg/l. The 2H has two pre-set reference values （DOP & PAO） for aerosol agents as well as a USER setting, which allows storage of a sampled concentration to be retained as a reference value.
2H Portable Photometer Specifications
SIZE:
WEIGHT:
ENCLOSURE: Instrument enclosure is rugged, die cast aluminum ａnd can be easily disassembled as required for recalibration ａnd service of internal components. The enclosure has a swiveling handle that also acts as a support, permitting tilting of the control panel display for easy viewing, as well as increasing the ease of transport.
POWER: 100 to 250 volts AC, 50/60 Hz fused power entry module with spare fuses. Automatically adjusts to virtually all standard voltages used worldwide. Please specify power supply cable when ordering unit.
AUTO-RANGING: Automatic from 0.0001% to 100.0%. Provides 6 decades of display ａnd eliminates the manual range selection switch.
AUTO ZERO: Automatically establishes zero by pressing the 0% button when sampling the airflow through the internal ULPA reference filter in the clear mode. Automatically establishes downstream reading as zero by pressing the 0% button when sampling the downstream airflow.
ALARM: Audible alarm in unit sounds when adjustable set point is exceeded. Visible alarm flashes on control panel ａnd scanning probe. Audible portion of alarm can be disabled.
BARGRAPH: Solid-state bar graph with high visibility green LED on control panel ａnd scanning probe.
AMPLIFIER: Solid-state linear amplifier.
PHOTOMETER ACCURACY: 1% of full scale for the decade in use in ratio metric mode.
DIGITAL DISPLAY: Shows % Leakage from 0.0001% to 100.0%
DYNAMIC RANGE: 0.0001 to 125 micrograms per liter. 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.
LIGHT SOURCE: 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: 0.5% full scale
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
