The Oakton Waterproof pH/DO 300 Meter is a handheld micro-processor-based pH, dissolved oxygen (DO), and temperature meter with manual or automatic temperature compensation, salinity and pressure compensation, five-point pH calibration with automatic buffer recognition, and a backlit LCD screen with adjustable brightness to enable viewing in dark environments. The meter is used for aqua cultural, environmental, industrial, and educational applications and takes two probes: a pH electrode with BNC connector, and an Oakton DO/temperature probe with a notched 6-pin connector and a replaceable membrane cap. It has auto-ranging for DO measurements, and auto-buffer recognition for pH calibration. The meter has a hold function, a ready indicator, and automatic shutoff after 30 minutes of nonuse. The advanced setup mode allows customization of meter parameters and displays calibration values and electrode slope for both pH and DO for diagnostic reasons. The meter has European Conformity (CE) certification and is dustproof and waterproof, with Ingress Protection 67 (IP67). DO meters are commonly used in water-quality testing applications.

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.

The Hanna Instruments HI 98703 is a portable turbidity meter designed to meet EPA reporting requirements. The meter has two, three, or four point calibration, can log up to 200 samples, and has automatic range selection. It operates on four 1.5V AA batteries and automatically shuts off after 15 minutes of non-use. The meter has a USB 1.1 or RS 232 interface, a tungsten filament lamp light source and a backlit LCD screen to reduce glare. Equipped with tag identification system for using with electronic tags in the field, and logs up to 200 measurements until data can be downloaded to Windows. The meter uses the Ratio Nephelometric Method (90 degree), and an adaptation of the USEPA Method 180.1 and Standard Method 2130 B. Turbidity ranges are 0.00 to 9.99; 10.0 to 99.9 and 100 to 1000 NTU + or - 2% of reading plus 0.02 NTU, with resolutions 0.01 NTU from 0.00 to 9.99 NTU; 0.1 NTU from 10.0 to 99.9 NTU; 1 NTU from 100 to 1000 NTU. Typical EMC deviation is + or – 0.05 NTU. Dimensions are 224 x 87 x 77 mm (8.8 x 3.4 x 3.0â€), with weight 512 g (18 oz.). Turbidity meters measure the loss of transparency due to suspended particles present in a solution. They are commonly used to measure the turbidity of water in both the field and laboratory. Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents, and buffer solutions.
