Manufacturer: Thomas Scientific Brand: LABOMED Model: Spectro SC

The Labomed Spectro SC visible-light spectrophotometer has a single-cell receptacle to measure transmission, absorption, concentration, and factor for routine spectro-analysis in a range of applications and industries, including chemical, biochemical, agriculture, environmental protection, and education. The instrument has a 320 to 1,100nm wavelength range, 0 to 100%T transmittance range, 0 to 2.5A absorption range, and 0 to 1,999C concentration range. The 6nm bandwidth provides more consistent results for low-concentration samples than does 1nm. It has a tungsten-halogen lamp, a silicon photodiode detector for reduced noise, and a monochromator with a 1,200 lines/mm grating mirror. A built-in stray-light filter increases accuracy. The spectrophotometer has a receptacle that accepts round test tubes and 10 x 10mm square cuvettes, and has a minimum sample size of 0.4mL. Capacitive-touch buttons ease cleaning and prevent liquids from entering the device. An RS-232C interface enables data to be transferred to a computer (sold separately).

The YSI 55 instrument is a handheld dissolved oxygen (DO) meter for field use, with a backlit LCD to enable reading in dark or dimly lit areas, and probe that is a non-detachable polarographic sensor, with a 50’ cable. The probe body has stainless steel to add durability and sinking weight. The meter has automatic temperature compensation, manual salinity compensation (0 to 40 ppt), and altitude compensation (0 to 10,000’). It runs on six AA alkaline batteries (included), is European Conformity (CE) compliant, and is water-resistant with Ingress Protection 65 (IP65). DO meters are commonly used in water-quality testing applications.

Dissolved oxygen (DO) meters measure the amount of dissolved oxygen present in water. The amount of DO helps to determine, for example, drinking water quality, the health of lakes or streams, and aquatic organism sustainability. A probe, also called a sensor or electrode, is inserted into the sample to perform the measurement, and the results appear on the meter display. Applications include sewage and water treatment plants, pollution control, fish farms, and various types of manufacturing. YSI manufactures instruments, sensors, and software for environmental water quality monitoring and testing. The company, founded in 1948, is headquartered in Yellow Springs, OH.
