  • Thermistor calibration for high accuracy measurements

    Calculating Steinhart-Hart Coefficients for High-Precision Readings Technicians and engineers often use thermistors to measure temperature in applications which require high accuracy. Thermistors operate by changing resistance as their temperature changes in a very predictable but non-linear way. This characteristic allows them to provide higher accuracy than thermocouples or ...

  • Calibration of a simple model for waste stabilisation pond performance in seasonal climates

    The paper describes the calibration of a model for waste stabilisation pond (WSP) performance in seasonal climates, based on the use of readily available climate data sets. Calibration data were taken from a wide geographical area of Canada and the USA, including coastal and moderately seasonal sites. Good agreement with measured values was shown using a biochemical oxygen demand (BOD) decay ...

  • Suction-Moisture Content Calibration of Filter Papers from Different Boxes

    The filter paper method is probably the simplest of the methods available for estimating the suction of a clay soil. The method measures soil suction indirectly by simply measuring the moisture content of a filter paper having been brought to the same suction as the soil. Calibration of representative specimens of the filter paper over a range of known suctions defines the suction-moisture ...

  • Determining Concrete Maturity with Temperature Monitoring

    Thermocouple Data Loggers Save Time & Improve Safety Concrete maturity is a measure of how much a batch of freshly poured concrete has cured. It is a quick indicator of the in-place strength at that point in time relative to the ultimate strength when the concrete is fully cured. Traditional measurements of concrete strength rely on compression tests such as made in a lab on field cured ...

  • Calibration of a passive, in situ, integrative sampler for monitoring of microbial biotoxins in aquatic environments

    In this work, an integrative passive sampler based on a silicone membrane filled with a suspension of γ-Fe2O3 at pH 3.5 was developed. The novel device was calibrated for the measurement of microcystin concentrations in water. Laboratory calibration studies of the passive sampling devises under controlled conditions of temperature, water turbulence, and analyte concentration were ...

  • Why is Calibration of Water Quality Testing Equipment so Important?

    The calibration of water quality testing equipment is as important as the tuning of a musical instrument. When people find out I’m a chemist, the first thing they ask me is, “Are you Walter White?” (This shows you the kind of people I typically run into). The second thing they ask me is, “Why is calibration so important?” Simply stated, calibration is how we adjust ...
