The Model 20 DO sensor utilizes proven galvanic sensing technology - without a question the most accurate and reliable DO sensing technology ever developed. The pure platinum cathode makes the sensor incapable of being poisoned by other gases often found in impure waters, such as hydrogen sulfide. This sensor utilizes the only DO sensing technology that is successful in continuous de-nitrification monitoring and control applications. It is also the only sensor design that can be used continuously in very violent pure liquid oxygen injection systems. Complete systems are supplied with over 5 years of sensor electrolyte and membranes. When used correctly these Teflon membranes will last well over a year and can be made to require a minimum of maintenance.

Manufacturer: Thermo Scientific Brand: Thermo Scientific Orion Model: STARA1230

The Thermo Scientific
Orion Star A123 Dissolved Oxygen Meter is a portable dissolved oxygen (DO) and temperature meter with automatic temperature, manual salinity input, and manual barometric pressure compensation to ensure accuracy. The meter can be calibrated by the water-saturated air method or Winkler titration method. The LCD screen displays icons, messages, and information such as DO reading in mg/L or % saturation, temperature in °C or °F, meter mode, and battery life. The ready indicator shows when readings are stable. The meter takes an Orion polarographic DO probe (sold separately) and runs on four AA batteries (included) or on AC power via the universal power adapter (sold separately). The memory holds up to 50 data points. The meter housing is waterproof, with Ingress Protection 67 (IP67). Additional certifications include European Conformity (CE), Technical Inspection Association (TÜV), and Federal Communications Commission (FCC) Class A limits. DO meters are commonly used in water-quality testing applications. SpecificationsDO concentration range0 to 20mg/LDO concentration resolution0.01, 0.1DO concentration relative accuracy+ or - 0.2mg/LDO % saturation range0 to 200DO % saturation resolution0.1, 1DO % saturation relative accuracy+ or - 2%Temperature range0° to 50° CTemperature resolution0.1Temperature relative accuracy+ or - 0.1Salinity factor0 to 45ppt, manual 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.

Manufacturer: Unico Brand: Unico

The Unico S1000 Visible Spectrophotometer comes complete with 10 mm test tube cuvettes (box of 12), 10 mm square cuvette adapter, USB port, dust cover, and user manual. The S1000 is precisely designed and ruggedly built. This easy-to-use spectrophotometer is ideal for student use in high schools, colleges, and for general laboratory testing. It is suitable for general analysis and experiments such as Beer-Lambert, absorption spectrum, chlorophyll, protein (Biuret test), and more. Includes a visible wavelength spectrum chart on the instrument panel, allowing the user to make the correlation between a wavelength number to an actual color on the visible light spectrum. A versatile instrument designed to accept both round optical glass or square 10 mm path length cuvettes. The built-in secondary filters reduce stray light and increase precision. The "student-proof" positive safety stopper integrated with the wavelength dial prevents damage to the monochromator and grating. Large digital display makes reading much easier, and USB interface allows customers to collect data easily. Unico S1000 Visible Spectrophotometer Specifications: Bandpass (Slit Width): 20 nm. Monochromator: Single beam, grating system (1200 lines/mm). Wavelength Range: 400 - 1000 nm visible. Wavelength Accuracy: ± 3 nm. Wavelength Repeatability: ± 1 nm. Stray Light: 2% T at 400 nm. Photometric Range: 0 - 100% T / 0 - 1.99 A. Photometric Accuracy: ± 2.0% T. Data Port: USB. Light Source: Tungsten halogen lamp. Power Requirements: (switchable) S-1000: 110 V / 50 Hz.
