Krueger Sentry Solid Glass Calibration Kits - Type Therma (H)

Upgrade Your Therma Gauge with Weather-Resistant Solid Glass

The Krueger Sentry Type Therma (H) Solid Glass Calibration Kit eliminates common points of failure in industrial liquid level monitoring. By replacing standard plastic components with a solid glass display and an aluminum lock nut, this kit provides a metal-and-glass barrier between your tank’s contents and the environment. This upgrade is specifically designed for high-heat applications or outdoor tanks where UV exposure, chemical fumes, and extreme weathering typically cause plastic indicators to warp, discolor, or crack.

This comprehensive kit includes everything needed to retrofit your existing Type H gauge for better durability and code compliance:

• Solid Glass Calibration: Resists clouding and provides superior clarity against acids, caustics, and biofuels (E85/Biodiesel).
• Aluminum Lock Nut: Replaces the standard red plastic nut.
• Duro Nitrile Gasket: Provides a secure, leak-resistant seal at the top of the gauge.
• Red Indicator: High-visibility internal float marker for accurate thermal expansion readings.

Choosing a solid glass top often satisfies fire inspector requirements for "glass and metal" barriers in sensitive environments. Like all Krueger Sentry components, these kits are Made in the USA and built to withstand the most aggressive industrial conditions without losing visibility over time.
