Calibration laboratories - Import export

Over time, various factors such as exposure to contaminants, age, incorrect operation, sensor deterioration, a drift in electronics or exposure to corrosive gases, can contribute to dewpoint instruments losing accuracy and reliability. To maintain accuracy and reliability, we advise an annual service and calibration. For instruments used in critical applications or aggressive environments, more frequent service and calibration intervals are recommended. Our Calibration Laboratory Engineers perform routine servicing, commissioning, fault finding, repairs and installation services in accordance with our accredited quality system. Our calibration range of -90 °C to +20 °C dewpoint is traceable to National and International Humidity Standards at the National Physical Laborarory (NPL). SHAW products are developed to be reliable, easy to install and simple to operate, We are committed to providing the highest quality products and services for accurate and reliable moisture measurement.

Reliable, accurate and offering superior senstivity, repeatability and speed of response. The SDT-Ex is suitable for continuous measurement of trace moisture in industrial process gases. This 3 wire, 4-20 mA, loop powered dewpoint transmitter utilises the ultra high capacitance SHAW moisture sensing technology and is certified intrinsically safe to ATEX and IECEx standards. Suitable for use in hazardous areas using a signal isolator and ideal for hydrocarbon, petrochemical and hydrogen applications. The SHAW SDT-Ex incorporates the unique AutoCal function designed by SHAW, allowing users to ensure accuracy between laboratory calibrations. Fully self-contained within a robust housing, the stainless steel construction provides weatherproof protection to IP66 (NEMA 4X). The output is configurable in 5 different units and various dewpoint ranges are available covering an overall range from -100 °C to +20 °C (-148 °F to +68 °F) dewpoint with an accuracy of ±2 °C (±3.6 °F) dewpoint.

Utilising the ultra high capacitance SHAW moisture sensing technology. The AcuDew is suitable for continuous measurement of trace moisture in process gases and dry compressed air, offering superior sensitivity, repeatability and speed of response. Various dewpoint ranges are available covering an overall range of -120 °C to +20 °C (-184 °F to +68 °F) dewpoint with an overall system accuracy of ± 2 °C (± 3.4 °F). The output is configurable to display in °C dewpoint, °F dewpoint, ppm(v), ppb(v), g/m3 and lb/MMSCF. Incorporating the unique AutoCal function designed by Shaw Moisture Meters, allowing the user to ensure accuracy between laboratory calibrations by checking the span of the hygrometer and correcting for any deviation. This high performance dewpoint transmitter can cope with extreme environmental conditions, offering protection to IP66 NEMA 4X. Its rugged construction has been tested to withstand 35,000 kilopascal (350 bar) maximum pressure.
