ISO 9000 & Other Quality Systems

Ensure you conform to the Control of Inspection, Measuring & Test Equipment by ordering your unit with calibration. All of our humidity meters are available with UKAS and traceable calibration options.

The AET-951W is a high accuracy combined humidity and air temperature meter that also displays wet bulb and dew point calculations. Both dew point and wet bulb can be accessed at the touch of a button. Its compact design with its 2 meter coiled cable connected probe make it ideal for a wide range of industrial and laboratory applications.

The unit takes samples twice a second and displays them on a 55mm LCD dual display that simultaneously displays humidity and temperature. It features a data hold function to freeze current displayed measurements and a min/max memory for temperature, humidity, dew point and wet bulb readings. Low battery indicators and auto power off feature after 15 minutes ensure the instrument has power when you need it.

This hygrometer comes equipped with a rubber moulded grip and tripod mount bush and is supplied with a soft carry case and a battery.
