Pressure measuring instruments - For gas and water installers

Product catalog summary

Overview: The document provides detailed information on the Testo 312 series pressure measuring instruments, specifically designed for gas and water installers. The series includes models testo 312-2, testo 312-3, and testo 312-4, each with specific features and applications.

Specifications:

testo 312-2: Fine pressure measuring instrument with a range of up to 40/200 hPa, featuring DVGW approval, alarm display, and calibration protocol. It is suitable for measuring flue gas draught, differential pressure, and gas flow pressure with high resolution.
testo 312-3: Versatile pressure meter with a range of up to 300/600 hPa, also DVGW approved, designed for load and gas-tightness tests on gas and water pipelines.
testo 312-4: Differential pressure meter for fine pressure measurements, suitable for checking resting and flow pressure of gas, and setting jet pressure on gas burners and boilers.

Technical Data:

Common features include storage temperature range from -20 to +60 °C, operating temperature from +5 to +45 °C, and a 9V block battery.
Each model has specific measurement ranges, accuracy, and resolution tailored to its application.

Procedures and Applications:

Pressure and gas-tightness tests on gas and water pipes.
Load tests and leakproofness tests on drinking water and waste water pipes.
Automatic measurement value recording for extended periods, useful for customer service and regulatory compliance.

Accessories: A range of accessories is available, including fast printers, rechargeable batteries, protection cases, calibration certificates, and various test plugs and probes to enhance the functionality of the instruments.

Recommendations: The document suggests using specific accessories and sets for comprehensive testing and maintenance tasks, ensuring accurate and reliable measurements.
