Model 912 : Multi-Canister Sampling Adapter
The Xonteck Model 912 Multi-Canister Sampling Adapter is designed for routing air samples to or from up to 16 canisters. The Model 912 is controlled by a Xonteck Model 901 Canister Sampler to step its internal rotary valve from canister to canister at a user-selected rate and order.
The Model 912 can automatically advance its valve position to the correct canister port after power failure recovery. After that, the selected valve position automatically performs a leak check prior to sampling, creating a pass or failure status on the Model 901.
