The new Pocket Colorimeter II Filter Photometer is a true go-anywhere instrument. It's lightweight and battery operated, suitable for extended field work or quick, on-the-spot process monitoring. The instrument has two channels in which measurements can be made. Each channel will accept a user-defined calibration curve. Up to 10 standards can be used to determine the calibration. The curve is generated by a point-to-point straight line segment between each standard used. Linear and non-linear positive or negative slope calibrations can be performed. A calibration curve may also be manually entered from the keypad if a previously determined curve has been made on the Colorimeter. At least two data pairs (concentration and absorbance) are required.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI98186-01

The Hanna Instruments HI 98186-01 is a portable microprocessor-based dissolved oxygen and temperature meter to help achieve accurate results in the lab and in the field. The meter includes an internal barometer and thermometer, and can calculate biochemical oxygen demand (BOD), Oxygen Uptake Rate (OUR), and Specific Oxygen Uptake Rate (SOUR). The meter offers automatic or manual calibration, with values provided in milligrams per liter or percent saturation. Temperature calibration can be set at one or two points by the user, and a “calibration time out” function prompts the user when a new calibration is necessary. A large, graphic-based LCD screen also makes calibration and meter readings easy to perform. The HI 98186-01 can log up to 400 samples, and is equipped with a USB cable for easy download of data to Windows. The meter has a DO range of 0.00 to 50.00 ppm or 0.0 to 600.0 % saturation (accuracy 0 to 300%: + or - 1.5% of reading or + or - 1.0%, whichever is greater; 300 to 600%: + or - 3% of reading; 0 to 30 mg/L: + or - 1.5% of reading or 0.10 mg/L, whichever is greater; 30 mg/L to 50 mg/L: + or - 3% of reading) with a resolution of 0.01 ppm/0.1% saturation. Barometric range is 450 to 850 mmHg (+ or - 3 mmHg within + or - 15 degrees C from the calibration point resolution) and a resolution of 1 mm Hg. Temperature range is -20.0 to 120.0 degrees C with automatic temperature compensation between 0.0 and 50.0 degrees C. Dissolved oxygen meters are used in a variety of applications to monitor the amount of oxygen present in water. Applications include sewage and water treatment plants, pollution control, fish farms, and various types of manufacturing. Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, electrodes, chemical reagents and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including a pH electro...

Manufacturer: Harvard Bioscience Brand: Biochrom WPA Model: 80-3000-44

Biochrom has helped to educate scientists in spectrophotometry for over 30 years. Our Biochrom WPA brand of spectrophotometers and colorimeters are used by schools, colleges and universities worldwide to educate the next generation of scientists. The Biochrom WPA CO7500 colorimeter is a value for money instrument that has been designed for use in educational establishments such as schools and colleges. It is compact, lightweight and ergonomically designed to withstand student use! This makes it ideal for use in busy teaching laboratories. The large display is easy to read and the instrument is simple to both set up and use, giving rapid results. The samples can be measured in either standard or semi micro 10mm path length cuvettes or in 16mm diameter test tubes (adapters for 10/12 mm test tubes are available). Available in mains only or mains /internal rechargeable NiMH battery versions. Measures Absorbance, % Transmission and simple kinetics. When used in kinetics mode - to study rates of reaction, for example - the CO7500 colorimeter takes readings approximately every second and these can be sent to a chart recorder (via the analogue output) if required. Alternatively, the results could be downloaded to an Excel spreadsheet for graphing and other manipulation using the appropriate accessories. The CO7500 colorimeter is designed to make life easier for technical staff, and to be low maintenance under demanding conditions. The eight filters (440, 470, 490, 520, 550, 580, 590 and 680nm) are encased in an integral filter wheel so filters cannot be accidentally lost or damaged. With no lid needed, this robust instrument is easy to use, clean and store. There is a drain hole at the bottom of the cell compartment so that spillages do not affect the instrument. Lamp life is extended as it is only on during the measurement cycle. Spare lamps are available and easy to install.
