MICHELL INSTRUMENTS says the new Michell S8000 –100 is a high-precision, low dew-point hygrometer designed to meet the demands of humidity calibration and standards laboratories. Michell says its engineers have used the latest developments in chilled mirror technology to achieve reliable, repeatable measurements of low dew points down to -100 °C, with an accuracy of ±0.1 °C, without the need for additional cooling.
