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: 10.1” x 14.3” x 5.8”
25.7 cm x 36.3cm x 14.7 cm
WEIGHT: 15.5 lbs. plus 2.5 lbs. for scanning probe and accessories = 18.0 lbs 7.0 kg plus 1.1 kg for scanning probe and accessories = 8.2 kg.
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 本公司經(jīng)營光度計，質(zhì)量保證，歡迎咨詢洽談。
