The devices of the ESS3 A1 series are used to measure pressure in water networks and can be installed directly in underfloor hydrants. These devices are ideally suited both for short-term measurements (for locating problems) and for long-term measurements over several years. Other applications include validation of pipe network calculations and documentation of leak tests according to DVGW W400-2.

The devices of the ESS3 R1 series are used to measure pressure, differential pressure, and temperature in supply networks for gas, water, and long-distance heating. The device also suited to measure general liquid and gaseous media in industry.


The devices of the ESS3 R2 series are used for leak testing in pipeline construction. In addition to the pressure measurement, the device is able to determine the temperature of the pipe line. The device automatically monitors the temperature-compensated test pressure and thus compensates pressure variations caused by temperature influences on the pipe line. Thus, the measuring results are more significant than pure pressure measurements.

  • Leak tests for gas supply in accordance with G469 B3
  • Leak tests for water supply in accordance with W400-2 / EN 805
  • Sewer leak testing according to EN 1610
  • Testing of cable protection tubes
  • Leak tests for process engineering / industry

  • Professional software with Excel export function for programming the logger and data analysis
  • Records up to 5 measurements at the same time
  • Temperature measuring range from -20 °C to +70 °C
  • Easy-to-change battery
  • Automatic measuring data backup when the battery runs out or is changed
  • Displays violations of limit values

When ambient conditions, for example in a laboratory, need to be documented securely and highly accurately, the testo 176 P1 is the right data logger. It has an integrated absolute pressure sensor and connection possibilities for two external temperature/humidity probes (optional).

User Manual

Pressure test kits of the PMS3000 series are used for leak testing in pipeline construction. The operating terminal, the measurement technology, and a log printer are housed in a rugged and waterproof plastic case suitable for use at construction sites. Via a color graphic touch display, all parameters of a leak test can very easily be entered and the test procedure controlled. All test methods of the DVGW directives G469 (A): 2019 and W400-2, Part 16 : 2004 are stored in the device. Intuitive operation is thereby possible even for inexperienced users without prior knowledge. Each test procedure ends with an automatic evaluation of the results of the leak test. During the test, a graphic depiction of the test procedure is available on the display. Other test methods in accordance with pressure vessel regulations, drains and sewers (EN 1610), cable protection tubes (e.g., ZTV TKNetz40) can also easily be integrated.
