RENTAL - Pfeiffer HLT 550 | Portable Helium Leak Detector - RENTAL

The Pfeiffer SmartTest HLT 550 is a highly versatile, microprocessor-controlled mass spectrometer helium leak detector designed for precise leak localization and measurement. As the core base unit of the Pfeiffer SmartTest series, the HLT 550 features an integrated turbomolecular pump and spectrometer cell but requires an external backing pump (such as a rotary vane or dry diaphragm pump), allowing users to customize vacuum roughing speeds based on specific test chamber volumes.

• Multi-Gas Detection: Detects ${}^4\text{He}$, ${}^3\text{He}$, and ${\text{H}}_2$ tracer gases.

• Dual-Mode Operation: Operates in both vacuum mode (under-pressure testing) and sniffing mode (over-pressure testing).

• Automatic Control & Protection: Built-in background suppression, auto-calibration via internal calibrated test leak (${10}^{-7}\text{ mbar l/s}$), and filament protection.

• Modular Interface: Removable control panel with dynamic graphic display and intuitive menu navigation.
