PID光離子氣體傳感器PID-AH(小量程) 

一、 PID-AH氣體傳感器產(chǎn)品簡介： 
光電離子探測器（PHOTO IONIZATION DETECTORS）可以測量(5ppb-50ppm)量程范圍的VOC（可揮發(fā)性有機物）和一些有毒氣體。許多有害物質(zhì)原料都含有VOC，PID由于其對VOC的高靈敏度，成為有害物質(zhì)早期危險報警、泄漏監(jiān)測等的實用工具。 

二、PID-AH氣體傳感器主要特性： 
1、 A系列標準尺寸，帶有微型聚光光源。 
2、 測量范圍：1ppb-50ppm

6、 過載：50ppm（以異丁烯參考） 
8、 在自由擴散情況下響應時間小于3秒 
9、 使用壽命大于5年（不含UV燈和柵極）
10、 A系列標準尺寸插針 

PID

With a PID, the sample gas is exposed to deep ultraviolet light from a lamp.

The emitted light ionises targeted gases in the sample so they can be detected by the gas detector and reported as a concentration (ppb or ppm).

The Alphasense PID can be installed in portable and stationary gas monitors that accept either Alphasense Ltd CH-A3 or other manufacturer’s compatible pellistor cells.

Thus providing complete PID capability in a package that has the same dimensional and electrical profile as pellistors (providing the electronics input circuit is designed to take the sensor’s output range). This opens up an incredible variety of environmental and safety applications in industrial, commercial and residential markets.

The Alphasense PID sensor is offered in two models, A1 and AH. They are virtually insensitive to humidity changes, providing unparalleled performance in a variety of applications.

PID-A1 has a linear dynamic range of 100-ppb to 6,000-ppm (Isobutylene).

PID-AH has a linear dynamic range of 5-ppb to 50-ppm (Isobutylene).

The sensors include a detector with 10.6eV lamp, lamp driver, amplifier circuitry, removable electrode stack & particulate filter.
