CM-5 SPECTROPHOTOMETER
The CM-5 bench-top spectrophotometer is an easy-to-use, color measurement instrument that features a keyboard and color LCD screen, eliminating the need for a computer. This product has the ability to automatically calibrate every start-up, measure a variety of sample sizes and forms, and includes internal calibration for standard chemical and pharmaceutical indices.
Easy 1-2-3 measurement – 1. Switch power on, 2. Position sample, 3. Press MEAS
反射測量
CM-5的測量端口在儀器頂部，因此，用戶只需要把被測的固體樣品放置在測量口上即可進行測量工作。不再需要使用夾具，也不必擔心樣品位置發生偏移。另外，使用培養皿套件（可選配件），還可以對液體，糊狀物，粉狀物等進行色彩測量。
透射測量
CM-5配有一個大型透射腔，可以測量厚達60mm的如玻璃、板材等樣品，且腔體邊界沒有限制，可以不受樣品長度和寬度的影響。
對於液體樣品，可以根據樣品的濃度來選擇3種不同厚度的比色皿進行透射測量。另外還有寬度為10mm的用戶定制比色皿可供選擇。
使用USB保存設置
您是否遇到過同一實驗室中很多人同時使用測色儀而造成的儀器設置混亂？CM-5可允許用戶將各自的儀器設置保存在USB隨身碟中，下次使用時儀器可以直接從隨身碟中讀取設置，而無須用戶重新進行煩瑣的設置。測量完畢後，用戶也可以將測量數據直接保存在隨身碟中，以進行進一步的數據處理和分析。
化工醫藥領域專用色彩指數
CM-5可以測量常用於化工和醫藥領域的幾個標準色彩指數：Gardner，Hazen/APHA，Iodine，European Pharmacopoeia 和US Pharmacopoeia。這些指數的校準曲線已保存於儀器中，因此，用戶可迅速簡便地測得這些專用指數。
