英國PP?Systems?
PP Systems科學(xué)有限公司是世界上著(zhù)名的生產(chǎn)開(kāi)發(fā)植物生理生態(tài)科學(xué)儀器的專(zhuān)業(yè)公司。公司創(chuàng )始于1984年，該公司的創(chuàng )始人之一Keith.J Parkinson博士為國際著(zhù)名的植物生理學(xué)家，他具有30年以上的生產(chǎn)光合測定儀器的經(jīng)驗。在創(chuàng )建PP Systems公司之前，他在英國著(zhù)名的Rothamsted實(shí)驗站從事光合作用的研究。在實(shí)驗站的最后幾年，他作為英國ADC科學(xué)儀器公司的咨詢(xún)專(zhuān)家,設計了LCA-2便攜式光合系統，該系統為世界上第一臺開(kāi)放式氣路的光合系統，由英國ADC公司生產(chǎn)銷(xiāo)售。他設計的葉室已注冊為“Parkinson葉室”，目前在國際上被多種光合系統廣泛采用。另外，Parkinson博士及其同事設計開(kāi)發(fā)了著(zhù)名的225MKII及MKIII型CO2/H2O分析儀。國際上第一臺真正差分式光合系統以及能夠自動(dòng)供氣和控制CO2的光合系統，均為PP Systems公司制造。公司合伙人David Stroud是著(zhù)名的紅外分析儀專(zhuān)家，70~80年代，他在A(yíng)DC公司負責紅外分析儀的設計?，F在PP公司生產(chǎn)的所有紅外分析儀都采用自己發(fā)明的先進(jìn)的調零技術(shù)，使儀器在長(cháng)期測定過(guò)程中具備穩定可靠和準確的性能。公司位于英國倫敦北面50英里處的Herts，Hitchin，有大量的研究開(kāi)發(fā)設施、原形產(chǎn)品的生產(chǎn)車(chē)間、微處理開(kāi)發(fā)系統及CAD工具。除了TPS-1,CIRAS-1, CIRAS-2便攜式光合測定系統外，公司還生產(chǎn)銷(xiāo)售用于光合作用研究、氣體分析、環(huán)境檢測、數據采集等十多種科學(xué)儀器設備。具有每年生產(chǎn)上千臺包括光合儀在內的各種生理生態(tài)儀器的能力。PP Systems公司的產(chǎn)品銷(xiāo)往世界50多個(gè)國家與地區，并在38個(gè)國家與地區設有代理。
由于北美地區對植物生理儀器日益增長(cháng)的要求和不斷擴大的市場(chǎng)需求量，PP Systems公司于1993年6月29日與美國馬薩諸塞州合作，在美國建立了聯(lián)合公司。公司位于馬薩諸塞州波士頓北面大約30英里處的Haverhill，主要從事研究、開(kāi)發(fā)、生產(chǎn)、經(jīng)營(yíng)及銷(xiāo)售服務(wù)。從1994年起，一部分生產(chǎn)設施由英國移往美國。
該公司把客戶(hù)的需求放在重要的地位，除了生產(chǎn)定型的產(chǎn)品以外，能夠根據客戶(hù)具體要求，設計或修改儀器硬件或軟件以滿(mǎn)足客戶(hù)的特殊需要。公司的另一項服務(wù)是利用公司的設備為客戶(hù)的新產(chǎn)品開(kāi)發(fā)和生產(chǎn)提供服務(wù)。
PP Systems公司尤其注重售后服務(wù)，在各個(gè)銷(xiāo)售國家設立了維修服務(wù)點(diǎn)，并聘請在植物生理生態(tài)領(lǐng)域有豐富經(jīng)驗的科學(xué)家作為技術(shù)支持，對用戶(hù)進(jìn)行技術(shù)培訓和常年儀器的維修業(yè)務(wù)。
Since 1984, PP Systems has been supplying quality, rugged and reliable instrumentation to customers throughout the world for high level research. We are considered a world leader in the design and manufacture of instrumentation for measurement of photosynthesis, soil respiration, chlorophyll fluorescence, CO2/H2O gas analysis and vegetation reflectance. Our customers come from a wide variety of scientific disciplines including agronomy, horticulture, biology, botany, crop and soil sciences, forestry, ecology, meteorology, oceanography and plant physiology to name a few. Our equipment is in use in over 100 countries worldwide and well documented in many prestigious scientific publications.
History of PP Systems
PP Systems was originally set up in 1984 by Dr. Keith J. Parkinson, whose work on the measurement of photosynthesis at Rothamsted Experimental Station led to the development of one of the first portable photosynthesis systems ever produced. Our UK office is based in Hitchin located approximately 50 miles north of London. In 1993, an associated company was established in the United States to look after sales and support of all North American customers. Our U.S. office is based in Amesbury, Massachusetts (located approx. 35 miles north of Boston) and has continued to grow over the years. Over the past 20+ years, we have developed into a small group of technical experts specializing in the design and manufacture of a wide range of scientific instrumentation including the popular CIRAS Portable Photosynthesis System, range of CO2 and H2O gas analyzers, vegetation and remote sensing instrumentation. Today, our UK and U.S. offices feature comprehensive design and development facilities, including prototyping workshop, microprocessor development systems and CAD tools, service, production and full calibration and testing capability. All instruments are produced to the highest standards that must meet strict quality control/assurance protocols established by management.

Customer Support
Customer support is very important to us and critical to the success of our business. All customers receive direct technical support from our own offices as well as through an extensive network of factory trained distributors. As a small company, we are able to offer our customers the personal, professional attention that they deserve. If you have an instrument in need of repair, please contact our service manager.

In many cases, we are able to customize system hardware or software to meet specific user requirements. Another service we offer is the use of our facilities for the development and production of equipment. If you have an idea for an instrument, we can assist you in its realization. All equipment manufactured by PP Systems is guaranteed for 12 months from the date of invoice against manufacturing faults and defective materials/components, parts and labor included. This guarantee does not cover misuse or damage caused due to unauthorized repair. We reserve the right to charge for customs clearance and return shipping/insurance if appropriate. For repairs beyond the warranty period, please contact us directly for advice.

In addition to our own manufactured products, our U.S. company is also the exclusive distributor for Hansatech Instruments, Gill Instruments (exclusive on 3 axis units) and Skye Instruments.
