A simple work station for those who run ASTM D3241 with a non recording model like the 230 series . Up till now there is no way to tell the apparent humidity of the air coming out of desiccant as well as the temperature of the sample in one easy to read display. The calibratable PH sensor is in the direct flow of the aeration air flow. Comes with Readout, K-type temp probe and humidity sensor, oversized desiccant cylinder and a convenient frame to hold the receiver. The readout has high and low set point limits to alert if the humidity is over the 32% limit. Order STAA-2030
