Abstract
A wood chip sampler is provided which is capable of extracting a repeatable and reliable sample of wood chips or similar particulate material from a product stream. The apparatus includes a sampling probe which has a slot which allows the product to enter the sampling probe. The probe is driven into the product stream with the slot in a six o'clock position, rotated through the twelve o'clock position to allow the product to enter the sampling probe, and then rotated to place the slot in a three o'clock position, and then retracted from the product stream into a housing. Once retracted, the probe is again rotated to place the slot on a six o'clock position, allowing the sampled material to be discharged by gravity into a hopper.
