TESTO 312-4
The TESTO 312 4 is an advanced electronic differential pressure measuring instrument designed for precise and reliable measurements in various applications, particularly in the gas and water industries. This device is essential for conducting load and tightness tests, as well as serviceability assessments on gas pipelines, ensuring compliance with industry standards.
Key Features
- Measurement Capabilities: The TESTO 312-4 can measure differential pressure in the range of 0 to +80 InH₂O (0 to +200 hPa), with an accuracy of ±1 InH₂O or ±1% of the full-scale value for higher ranges. This makes it suitable for fine pressure measurements in various scenarios.
- Data Logging: The instrument can record up to 25,000 measurement values, allowing for extended monitoring over time. This feature is particularly useful for tracking pressure fluctuations and ensuring compliance with regulations.
- Versatile Applications: The TESTO 312-4 is designed for a range of testing scenarios:
- Tightness and Serviceability Tests: Conducted according to DVGW TRGI 2008 standards for gas pipes.
- Load Testing: Assessing the integrity of gas pipes using an optional high-pressure probe.
- Pressure Testing: Applicable for both drinking water pipes (using water or air) and wastewater pipes, following relevant standards such as DIN 1988 and DIN EN 1610.
- User-Friendly Interface: The device features a clear display that shows real-time measurements, making it easy for users to interpret data quickly.
- Temperature Measurement: The TESTO 312-4 can also measure temperature, enhancing its utility in applications where temperature and pressure are interrelated.
- Durability and Design: Built with robust materials, the TESTO 312-4 is designed for reliable performance in demanding environments. Its compact size and lightweight design (approximately 600 g) make it easy to handle and transport.
Applications
The TESTO 312-4 is particularly valuable in the following areas:
- Gas Industry: For checking gas pressure regulators, ensuring safe operation of gas burners and boilers, and conducting gas-tightness tests on newly installed or existing gas pipelines.
- Water Industry: For pressure testing of drinking water and wastewater pipes, ensuring compliance with safety and regulatory standards.
- HVAC Systems: Assisting in the setup and maintenance of HVAC systems by providing accurate pressure measurements.
The TESTO 312-4 Differential Pressure Measuring Instrument is a versatile and reliable tool for professionals in the gas and water industries. Its advanced features, including extensive data logging capabilities and compliance with industry standards, make it an essential instrument for ensuring safety and efficiency in pressure measurement tasks.
