H2S Lab Process Analyzer – XLE 105-1 LAB

One Great Product in Three Styles to Fit Your Every Need in an H2S Process Analyzer

Texas Analytical Controls, Lab Unit, accurately measures the H2S for various ranges in a laboratory atmosphere.  The analyzer is lightweight, easy to use and extremely reliable.

Truly the heart of the system; the TAC electrochemical sensor recognizes the presence of H2S in just seconds. The sensor typically lasts one year and can be changed in just seconds. Calibration is simple and can be done is less than 6 minutes. An LED indicator on the front panel tells you when the analyzer is in the calibration mode.

TAC specializes in customizing our products to fit your needs.  The Lab Unit can also be ordered to measure two different ranges.  For Example:  Low Range 0-100 PPM and automatically switch to a High Range 100-5000 PPM

We have updated our analyzers so that replacing H2S sensors are done by removing just one thumbscrew.

Click “VIDEOS” tab and watch “How to Replace H2S Sensors”

The analyzer will display “Sensor Weak” when the H2S sensors are 75% used.  This new feature provides the operator a warning to change the sensors.

Displays Historical Trend of H2S Readings within the previous hour

The display will read “Flow Fail.”  If the regulators and the flow meter(s) are not working properly and the sample to the analyzer is obstructed.

The SD memory card is used to store Historical Calibration and Alarm Data.  Each analyzer has the ability to be given a Name or ID.  The selected ID name will also be displayed when downloading data from SD card to a spreadsheet.
