Simplicity meets accuracy in the new Thermo Scientific Orion Star A100 Meters—an excellent choice for environmental testing, water and wastewater treatment, quality control in food and beverage testing, and education. Affordable yet reliably effective, the meters feature a large LCD, simple button layout, and on-screen messages. Informative displays indicate measurement along with temperature, battery life, electrode status, meter mode, calibration history, power source, and more. On-screen messages guide users through calibration and setup. Choose from units measuring pH, conductivity, or dissolved oxygen (DO). The pH meters offer automatic recognition of USA, NIST, and DIN buffer sets and 3-point calibration with easy recall of slope data. Conductivity meters match range with selectable cell constant from 0.1 to 10.0 K and increased accuracy with selectable reference temperature of 20 or 25ºC. Dissolved Oxygen (DO) meters feature automatic compensation for temperature, salinity and barometric pressure, and direct read in % saturation or mg/L (ppm).
