Lighthouse Solid Secondary Standard is a solid Secondary / Verification Standard for HF scientific model turbidimeters. It is intended to be used as a quick & convenient “check standard” to verify that the turbidimeter being checked has maintained calibration. It can help determine whether a full Primary calibration of the turbidimeter is required. Designed for use with the HF scientific MTOL+, M100+, Micro TOL and Micro 100 series Turbidimeters, it can be used as often as needed and has no expiration date. This verification standard can make daily calibration checks much easier to accomplish and is especially useful for facilities having a daily check required by permit such as a re-use water facility.
