3, TDA-2H气溶胶光度计产品介绍:
TDA-2H气溶胶光度计是新型的功能齐全的便携式数字光度计。秉承简化操作和使用中免维护的理念去为用户设计的。它的基本的用途是侦测并量度空气中物质的浓度。三部分流速传感和光电显示灯提高了数据的稳定性。
微处理器控制的TDA-2H气溶胶光度计能使操作员迅速的设定操作功能和参数。仅仅用这7个按键去编辑和操作,这是非常容易做到的。数字显示屏有一个安装的菜单和对话框操作的代码是供操作员使用。浓度测量的范围从100 到 0.0001 微克 / 升。TDA-2H气溶胶光度计有两个预设DOP & PAO参数数值为气体生产机构或用户选择,这样就可以存储一些样品的浓度作为一个参考值。
TDA-2H气溶胶光度计可以自动进行归档(6组),完全免除了手动的麻烦,数字显示泄漏百分率析像度由100.00%到0.0001% 。
高密度线条图可以使操作者快速测定泄***,为自动归档数字显示提供了特别准确的悬浮微粒子百分比浓度和泄漏百分比,数字显示亮度可调节。
悬浮微粒子上游100%浓度和下游0%浓度底线可以通过100%和0%按键自动设定,免除了其它方法的附带设定。
声音及视像的报警设定可简易快速地预设或取消,当达到报警点时,显示面板和探头会闪亮。
当采用不同的悬浮微粒子剂时,有3个可预设程序的参考数值,操作者可快速选择符合不同测试要求的DOP、PAO或其他悬浮微粒子剂。
TDA-2H气溶胶光度计(包括电线和操作手册)外壳采用坚固的模注铝材,适用于工业及实验室环境。扫描探头包括所附属的连接管和管嘴,是机器的选配件。扫描探头和TDA-2H型便携式光度计一样有数字显示和线条图,使操作者快速准确的找出偏远地点的泄漏点和决定其他泄漏比率,当超过报警界线时,显示板会闪亮报警。
新设计的延伸管可以使管嘴伸向不同的角度,使更有效地扫描任何表面,可提供三个不同的管嘴去符合不同的测试标准和方法,使扫描更快更准确。扫描探头是一个选配件。

英文详细介绍:
Description
The 2H is the latest digital photometer ***ailable 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 functi*** and parameters. It is easily programmed and operates with just 7 push butt***. 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 Specificati***
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 concentrati*** 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 resp***e; 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
