UNSPSC 41111950: Level indicator

There are various types of level indicators: one type is a bead type, some are of visible transparent material, some are of float type.

UNSPSC 41111950 Level indicator is a Commodity code that encompasses laboratory and scientific measurement instruments, detectors, sensors, and monitoring systems used by state and local environmental, public health, water, and educational agencies. State and local governments procure under this code a broad range of specialized equipment including atmospheric gas detection systems, tandem mass spectrometers for water quality analysis, environmental conditions monitoring systems for laboratory facilities, and related calibration standards, accessories, and support services. The issuing bodies span state environmental protection agencies, city water utilities, county public school districts, university systems, and state departments of agriculture—a mix reflecting the breadth of environmental monitoring and laboratory operations across state and local infrastructure. Work being solicited includes installation, training, maintenance, parts provisioning, and extended support contracts; vendors routinely must demonstrate multi-year experience, hold certifications, maintain local parts stock with guaranteed response times, and provide on-site commissioning and operator training.
