H2O Monitoring Made Simple
Choose Texas Analytical Controls for reliable, economical H2O monitoring. With a unique H2O sensor cross interference, the TAC analyzer is your first choice for reliable H2O monitoring to protect pipelines from corrosion.
Easy to Operate and Maintain
The TAC analyzer outshines the competition when it comes to ease of operation and maintenance.
Sensors typically last 2 years and can be changed in just a few minutes. No special tools are required.
Calibration is performed at the TAC factory prior to shipping. Field calibration is not required.
Full Technical Support
You will find the analyzers are easy to maintain. Technical support is available via phone or in person by one of our service technicians.
