— The TTi 2000 Colorimeter (M-2000) for testing pools and spas can be used to monitor more than a dozen parameters. User-friendly features include the ability to create your own menus of favorite tests, adjustable backlighting on the large liquid crystal display, and an auto-read function on the test timer, so you never miss seeing a result because you got preoccupied with other tasks. Unlike competing models, our meters come with data interface software, an AC power adapter, a USB cable, and all other essentials. The meter also offers free lifetime software upgrades as new tests are developed.
