Technical Features and Field Applications of the Testo 312-4

The core of this basic set is the Testo 312-4 differential pressure gauge, which offers versatile measurement options for diverse field scenarios. Whether you are monitoring gas pressures in heating systems or performing differential pressure checks on filters and fans, this device delivers reliable data. The integration of an internal differential pressure sensor and support for external probes allows for flexible usage without compromising accuracy. This versatility ensures that technicians can rely on a single instrument for multiple testing requirements, streamlining workflows and reducing equipment loadout.

• Differential Pressure (Internal Sensor): The device features a measuring range of 0 to +200 hPa with a high resolution of 0.01 hPa. It delivers exceptional accuracy, specifically ±0.03 hPa in the 0 to +3 hPa range, ensuring precise low-pressure readings critical for combustion analysis and filter monitoring.
• Pressure Measurement (External Probe): Supporting an external probe, the gauge measures pressure from 0 to +25 bar. The accuracy is maintained at ±0.6 % of full scale value (fsv), making it ideal for checking gas supply lines and hydraulic systems where higher pressures are present.
• Temperature Measurement: The device supports Type K (NiCr-Ni) thermocouples. While the measuring range depends on the specific probe used, the internal accuracy is ±0.4 °C in the -100 to +200 °C range, allowing for precise temperature correlation during pressure tests.
