Thermometers are ideal for round-the-clock monitoring of semi-solids, air/gas, or liquids in incubators, refrigerators, freezers, water baths, and outdoor tanks. Useful in wet lab/plant areas and outdoors. Thermometers may be placed anywhere. Easy-to-view 6.4mm (1/4") high LCD digits can be read at a glance. LCD operates in environments above freezing. Probe with stainless steel sensor performs accurately when under water. Records highest and lowest temperature readings over any time period. Reading updates every second. Housing is waterproof and shockproof. Ordering Information: Thermometers are supplied with probe with 3m (10') cable, magnet to attach thermometer to metal, suction cups and Velcro? fastener to mount thermometer on any surface, and 1.5V silver-oxide battery for one year of continuous “always on” monitoring. A serial numbered certificate is provided from an ISO 17025 calibration laboratory accredited by A2LA to indicate instrument traceability to standards provided by the National Institute of Standards and Technology.

PBDEs由于其阻燃效率高,热稳定性好,用量小,对材料影响小,价格便宜为广泛的应用于电子、电器、化工、纺织、石油等领域。但是由于PBDEs具有挥发性,可以散逸到空中,随大气长距离迁移。且具有亲脂性,可以随着食物链生物放大。目前PBDEs在环境和人体中污染程度的增长速度引起社会关注。欧盟在2006年正式启用RoHS指令对铅、汞、镉、六价铬、PBBs、PBDEs进行严格限制,同年我国也颁布了《电子资讯产品污染控制管理办法》,对铅、汞、镉、六价铬、PBBs、PBDEs等试剂的添加及应用进行限制和监管。 北京美同达科技有限公司推出的阻燃剂产品套包,将阻燃剂检测的相关170多种的PBDE同系物,配套使用的PBDE代谢物、PAHs、氘代内标物及配套用的耗材配件全部网罗其中,随订购的标样附带质检报告、材料安全数据卡,并且可以为用户提供专业标样的定制服务。 部分产品清单如下: Mercury,汞 Lead,铅 4-Bromophenoxybenzene,溴联苯醚 2,5-DIBROMODIPHENYL ETHER,二溴联苯醚 2,4,4?TRIBROMODIPHENYL ETHER,三溴联苯醚 2,2',4,4'-Tetrabromodiphenyl ether,四溴联苯醚 2,2',4,4',5-Pentabromodiphenyl ether,五溴联苯醚 2,2',4,4',5,6'-Hexabromodiphenyl ether,六溴联苯醚 2,3,3?4,4?5?6-HEPTABROMODIPHENYL ETHER,七溴联苯醚 2,2?3,3',4,4?6,6'-OCTABROMODIPHENYL ETHER,八溴联苯醚 2,2',3,3?4,4?5,5',6-NONABROMODIPHENYL ETHER,九溴联苯醚 Decabromodiphenyl oxide,十溴联苯醚 4-Bromomethyl-2-cyanobiphenyl,溴联苯 2,4-DIBROMOBIPHENYL,二溴联苯 2,2',5-TRIBROMOBIPHENYL,三溴联苯 2,2?4,4?TETRABROMODIPHENYL ETHER,四溴联苯 2,2',4,5,5'-PENTABROMOBIPHENYL,五溴联苯 HEXABROMOBIPHENYL,六溴联苯 DOW FR-250 (OCTABROMOBIPHENYL),七、八、九溴联苯混合物 DECABROMOBIPHENYL,十溴联苯
