XC-623 Series Console

XC-623 Series Console

The New XC-623 Source Sampler from Apex Instruments is designed for manual sampling of gaseous pollutants from stationary sources, e. g. stacks, flues, vents or pipes.  The console is most commonly used for EPA Methods 6, 26 and VOST (Methods 0030 and 0031).  However, it’s suitable for most sampling methods requiring accurate sample volume measurements at constant sample flow rates between 300 ccm to 5 LPM.

Description

The metering console includes a precision dry gas meter fitted with a high-resolution rotary encoder, a leak-free pump, a vacuum gauge, flow control valves and a rotameter for monitoring the gas flow rate.  A 32-bit microcontroller converts the sensor inputs and displays the totalized sample volume, temperatures and pressures into user selectable units.  The transflective LCD display is sunlight-readable and backlit so it can be seen in the dark.  Three advanced, self-tuning 1/32 DIN temperature controllers with individual solid-state relays are used for controlling heaters, e.g. probe, filter, and valve heaters.

The digital LCD screen displays the dry gas meter volume, elapsed time, the dry gas meter pressure (Pm), and the temperature of the selected thermocouple.  A rotary switch is used for monitoring up to 6 different temperatures. Coarse and fine valves are used to control the sample flow rate and for adjusting the vacuum during leak checks. A quick connect provides a convenient connection for the sample vacuum line.  An easy-to-use 4-button keypad is used to reset the gas volume and elapsed time at the start of each sample period along with other functions.

This console is housed in rugged and lightweight roto-molded linear low-density polyethylene (LLDPE/LMDE) case three stainless steel carrying handles.
