The Thermo Scientific
Orion Star A113 Dissolved Oxygen Meter is a benchtop 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, and the memory holds up to 50 data points. The meter takes an Orion polarographic DO probe (sold separately) and runs on AC power via the universal power adapter (included) or on four AA batteries (sold separately). The electrode arm with holder (included) helps to place and maintain probes in samples. The meter housing has Ingress Protection 54 (IP54) to withstand splashes and can be wall-mounted to save table space. 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 man...

The Jenway 035-121 500μl glass fluorimetry cuvette has a PTFE lid. This cuvette is used to take visible wavelength measurements at a minimum of 320 nanometers (nm) and between 360 to 2,500nm. The glass is clear on four sides to take measurements at right angles. It has a PTFE (polytetrafluoroethylene) lid to help contain samples and prevents spills and evaporation.Cuvettes are specialized test tubes, used in laboratory or field research, to hold samples for optical analysis by instruments such as spectrophotometers, fluorometers, and turbidity meters. Their size or capacity is most often measured in milliliters or microliters. A cuvette may be cylindrical in shape, but square or rectangular cuvettes are used when light refraction must be minimized. A rectangular cuvette may have four clear sides, for use in a fluorometer, or only two clear sides opposite each other, for use in spectrophotometry. The path length of a cuvette, often given in millimeters or centimeters, is a measure of the distance that light travels through a sample in the cuvette. Cuvettes are made of transparent quartz, glass, or plastic. Each material offers different advantages: quartz is best in the ultraviolet light range, glass and plastic in the visible light range, and glass yields more precise results. Cuvettes may come with a cap for containment or a stopper for sealing. Cuvettes are also called cuvets, absorption cells, or sample cells.Bibby Scientific manufactures laboratory equipment such as shakers, centrifuges, incubators, and water baths under the Stuart, Jenway, and Techne brand names. The company is headquartered in Stone, Staffordshire, UK.

These sturdily constructed photometers use glass filters for colorimetric and turbidimetric analyses to obtain readings on a KlettTM scale. The measurements are in Klett units, and they are directly proportional to the solution's OD, according to Beer's Law. Other photometric instrument scales are 'shorter' than the Klett's and thus the Klett's readings offer greater exactness. Accessory filters provide measurement over the entire visual range and measurements for both color and turbidity are allowed. A pair of matched photovoltaic cells and a suspension galvanometer allow a wide range of readings; the unit is unaffected by light and ambient temperature. The galvanometer offers excellent exactness for its class, and features an illuminated logarithmic scale, with markings from 1 to 1000 KlettTM. Two models are available. The Industrial Model is compatible with rectangular cuvettes, which may be employed in one of two orientations. Readings are obtained at depths of 10mm, 20mm, or 40mm. An optional reduction plate may be used to reduce solution depth to . An optional adapter allows test tubes to be used in the Klett unit. The Clinical Model employs regular x 125mm test tubes. Can choose to purchase both calibrated or uncalibrated tubes. Micro test tubes may also be employed for small volume samples (as low as 2.5 ml). Both versions of the KlettTM include the blue (400-450nm) and green (520-580nm) glass filters. Comes with clear instructions, standards and usage guides for several common tests. Available in 115 or 220V. Durable construction for long service life• Reproducible results with exactness to % on the full scale• Measurements for both color and turbidity are possible• Balanced electrical circuits that are fully compensated avoid the use of storage batteries or current regulators Description: color filter, KS-6225TSpectral Range: 590-660

The YSI® Professional series provides plug-and-play capabilities to give you a meter with as much functionality as needed. Build your own system by ordering the meter, probe(s), and cable(s) without having to purchase additional meters or unnecessary accessories. Easy-to-use meters feature graphic display with detailed messages and instructions that translate to less time reading manuals. Rugged rubber over-molded case protects meters during use. Meters are IP67-rated and are waterproof, even without the battery lid. Meters accept either classic polarographic or "instant-on" galvanic DO sensors with screw-on membrane caps for ease of maintenance. Two-point DO calibration and automatic barometric compensation provide greater accuracy. Conductivity measurements are performed with a four-electrode conductivity cell for accurate measurements over the entire range. Meters automatically correct the DO measurement based on measured salinity values. Modular meter allows configuration to your specific application Handheld meter offers menu-driven software for added convenience Backlit graphic display and keypad Cables and probes are not included. order separately
