CEM Heated 3 Point Rata Probe

The CEM Heated 3 Point Rata Probe makes CFR Part 60 sampling as easy as 1,2,3. The electrically actuated C-276 Hastelloy ball valve allows 1 of 3 user defined traverse points to be sampled. A calibration gas tee is included on point 1. Sample Points 1, 2, or 3 can be selected manually at the probe (Local Mode) or from remote dry contracts or data logger (Remote Mode). Built in digital controllers maintain oven and probe at desired temperature. 3 stainless steel fritted on the probe and 3 glass fiber filters in the oven keep the sample clean. A strain relief is provided for a steady heated sample line connection.
