Electronic pressure gauges that store max/min readings. Ideal for burst pressure testing, process variable analysis, and diagnosing supply drop-offs.
Max/min stored reading electronic pressure gauges are specialized instruments designed to capture and display the highest (peak) and lowest (valley) pressure values a system has experienced. This functionality is invaluable for design and process engineers, as well as maintenance technicians, enabling precise determination of burst pressures, verification of process variable limits, and diagnosis of issues like pressure drop-offs in gas or water supplies. Often referred to as “tattle-tale” or “hi-lo” gauges, they provide crucial data for system analysis, unattended monitoring, and ensuring operational integrity by revealing critical pressure excursions that might otherwise be missed.

These electronic pressure gauges are specifically engineered to capture and retain the absolute highest and lowest pressure values experienced by a system since the last memory reset. The digital interface not only offers clear readability but also ensures precise data logging of these critical peak and valley pressure events, which is invaluable for unattended monitoring or diagnosing intermittent system behaviors.
The ability to reset the memory for these stored readings is a key operational feature. This allows engineers and technicians to define specific monitoring periods, whether for a short-term diagnostic test cycle, a quality control check during a manufacturing batch, or for longer-term observation of system performance trends. The duration between these resets is typically constrained only by the instrument’s battery life or power supply integrity.
A significant application for these gauges is in determining the burst pressure of components such as hoses, pipes, tanks, or seals. By capturing the precise pressure at which a component fails, design engineers can verify material specifications, validate design calculations, and ensure products meet stringent safety standards. This is critical in industries developing or using pressurized fluid or gas systems, from automotive to aerospace.
Identifying the operational limits of process variables is another crucial use case. In industrial settings like chemical plants, refineries, or manufacturing lines, these gauges help process engineers monitor for pressure excursions that might exceed safe operating windows or indicate inefficiencies. The stored maximum reading can highlight overpressure events that could damage equipment or create hazardous conditions, while the minimum reading might reveal insufficient pressure for a process to complete correctly.
These instruments are also highly effective for detecting sudden or gradual drop-offs in gas or water supply lines. For instance, a maintenance technician could use a max/min gauge to diagnose suspected leaks in a compressed air network by observing if the minimum pressure recorded overnight is significantly lower than expected. Similarly, they can pinpoint issues in water distribution systems or hydraulic circuits where pressure integrity is paramount for consistent operation.
The colloquial term “tattle-tale” gauge aptly describes their function; they effectively “tell the story” of the pressure variations a system has undergone, especially when no operator is present. This capability is essential for troubleshooting sporadic faults that might otherwise go unnoticed, such as momentary pressure spikes that trip safety systems or dips that cause intermittent equipment malfunction. Other common industry terms like “hi-lo,” “peak/valley,” or simply “max/min” gauges all refer to this same core capability.
The method of displaying the highest, lowest, and current pressure readings can vary. Some models offer simultaneous display, providing an immediate, comprehensive overview of the system’s current state alongside its historical extremes. Others may require the user to cycle through readings, which can allow for larger, more easily legible digits for each individual value. This choice often depends on the specific diagnostic or monitoring task at hand, influencing how quickly and effectively a technician can interpret the system’s pressure dynamics. These gauges are commonly found on test benches for component validation, in field service kits for system diagnostics, and in fixed installations for long-term performance monitoring of critical machinery.
