Colorimetric Air Quality Monitor
SKU# 44075
Similar to #44070, this unit utilizes a 3-phase sensor disk which progressively changes shades of blue as the himidity increases. Humidity levels of 20%, 40% and 60% are detected; dessicants should be renewed as the 40% segment begins to fade. Since this model does not sense carbon monoxide, use this device where the chance of carbon monocide in the intake air is low; also use it to maintasin very low dew points in air used for cold water diving or deep TEK diving. Replacement sensor disk: Order #44076.
