RT and RTA-2 dry material samplers are made to sample from pneumatic lines and conveyors, either positive or negative. These fully automatic air-operated samplers deliver accurate, frequent samples with no metal-to-metal contact between parts. The RTA-2 ejects the sample with a controlled jet of air. At rest position, the sample tube is out of the process line. The RTA-2 is completely explosion-proof so it’s perfect for hazardous locations. The RT discharges the sample by an auger. At rest position, the sample tube is out of the process line.
