Cole-Parmer 4192CP NIST可追溯湿度卡

Cole-Parmer 4192CP NIST可追溯湿度卡

卡显示当前达到的最大湿度和湿度

易于读取卡是瓶子，化学品，塑料包装袋，电子产品，dessicators和储存容器使用。最大范围（当暴露于24小时或更达到最高湿度）是在10％RH下的增量为50〜90％RH-橙色点指示器变为黄色。最大内存范围是可读为±5％RH在75°F（24°C）的精度。 

可逆当前湿度（0〜100％RH）中的变化从蓝色到明亮的粉红色在10％RH下的增量; ±2.5％RH的准确度在75°F（24°C）。到达卡即可使用，每张卡单独密封在一个明确的防潮袋干燥剂以保持干燥卡，并提供较长的保质期。 

配备：NIST可溯源证书。

NIST-Traceable Humidity Card

Card indicates both the current humidity and the maximum humidity attained!

Easy-to-read card is ideal for use with bottles, chemicals, plastic bags, electronics, dessicators, and storage containers. Maximum range (highest humidity attained when exposed for 24 hours or more) is 50 to 90% RH—orange dot indicator changes to yellow in increments of 10% RH. Maximum memory range is readable to an accuracy of ±5% RH at 75°F (24°C).
Reversible current humidity (0 to 100% RH) changes color from blue to bright pink in increments of 10% RH; accuracy of ±2.5% RH at 75°F (24°C). Card arrives ready for use—each card is individually sealed in a clear moisture-barrier bag with dessicant to keep the card dry and provide for an extended shelf life.
What's included: NIST-traceable certificate.
