The Koehler Penetrometer Bath provides an ideal environment for maintaining consistent temperature conditions during penetration tests of petroleum products, lubricating greases, waxes, and bituminous materials. Its full-visibility design features a spacious shelf that accommodates a variety of ASTM-standard containers, allowing samples to remain immersed during testing for optimal accuracy.
The system incorporates a microprocessor-based digital temperature controller, maintaining bath temperature with exceptional ±0.05°C stability throughout the operating range. The large LED display provides real-time temperature readout in switchable °C/°F formats, while a dual-speed circulating pump ensures uniform temperature distribution.
Safety and reliability are enhanced by independent over-temperature and low-liquid cut-off protection, preventing overheating or equipment damage. A built-in cooling coil allows the use of refrigerated coolant or tap water for precise low-temperature control. Compatible with both manual and microprocessor penetrometer models, this bath offers unmatched flexibility and precision for laboratory testing.
