Quick Decision Guide
Choose TLS-350 if...
You have existing infrastructure, limited budget, or basic compliance needs. Note: No longer manufactured - consider TLS-450 for new installs.
Choose TLS-450PLUS if...
You need remote monitoring, touchscreen interface, or are upgrading from TLS-350. Best balance of features and cost.
Choose TLS-4 if...
You need predictive analytics, API integration, high tank counts, or are building a future-proof enterprise deployment.
