The wastewater network

A functioning water cycle includes not only the drinking water network but also the wastewater network. Just like the gas, electricity and water networks, the wastewater network is also part of the so-called critical infrastructure and is therefore subject to special protection. An intact wastewater network helps to protect the environment from pollution, save energy and ensure responsible use of the scarce resource water. In addition to repairs in the case of serious defects, maintenance work in the form of regular inspections is crucial. Depending on the type, these activities require special measurement technology, for example to guarantee the safety of people from possible hazardous substances. We offer you the right equipment for carrying out clearance measurements before a manhole inspection or for leak tests on wastewater pipes and sewers in accordance with DIN EN 1610.

Leak test according to EN 1610

Installation and testing of wastewater and sewers are regulated by the European standard EN 1610, which also requires a final leak test of newly built or renewed wastewater pipelines. The smart memo guides you through the test in an automated process, displays measurement data and progressions, stores and documents all relevant test data.

OLLI as a manhole warning device

The most common hazards when working in manholes are hazards from substances, which include solids, liquids, vapours and gases in quantities and concentrations that are hazardous to health, as well as the risk of falling. In addition to oxygen deficiency (O₂), methane (CH₄), carbon dioxide (CO₂) and hydrogen sulphide (H₂S) are the most common gases in the vicinity of manholes.

OLLI function-tested

Gas measurement & warning device with certified measuring function for explosion protection. This variant of the OLLI is included in the BG RCI list of function-tested gas detectors (see article 280000 for the variant without certification). Explosion-proof & compact diffusion hand-held measuring device. It can be used for up to 5 combustible and toxic gases as well as oxygen and comes in an extremely rugged 2C synthetic housing with rechargeable and explosion-proof Li-ion battery pack. Charging the battery in potentially explosive atmospheres is not permitted! Up to 3 gas sensors can be installed (Ex/Ox/Tox). Assembly is based on customer requirements. The device can optionally be equipped with a pump and pressure sensor. Operating time > 50 hours (depending on type & number of installed sensors and ambient conditions, w/o illumination) Measurement ranges are subject to sensor assembly Dimensions: 136 x 78 x 43 mm Weight: approx. 350 g Explosion-proof measurement instrument (active & passive) Measuring function certified for methane (CH4), propane (C3H8), oxygen (O2), carbon monoxide (CO), carbon dioxide (CO2), hydrogen sulfide (H2S) according to the following standards: EN 60079-29-1 EN 50104 EN 45544-1 EN 45544-3 ATEX Marking: II 2G Ex ib db IIB T4 Gb (EU-)type examination certificates: BVS 17 ATEX E 043 X TÜV 21 ATEX 8596 X TÜV 21 PTG 7001 X 968/FSP 1940.05/21 Kennzeichnung IECEx: Ex ib db IIB T4 Gb IECEx BVS 21.0085X Temperature range: -20°C <= Ta <= +50°C

Clearance measurement and safe access to containers

DGUV regulation 113-004 requires trained personnel with expertise in measuring devices, measuring methods and the hazardous substances to be measured for release measurements in containers, silos and confined spaces. The seminar content includes the basics of occupational safety according to the ArbSchG, BetrSichV, ArbStättVO, correct ventilation and the effect of nitrogen gases and oxygen deficiency or excess on the body.

Clearance measurement and safe access to containers

DGUV regulation 113-004 requires trained personnel with expertise in measuring devices, measuring methods and the hazardous substances to be measured for release measurements in containers, silos and confined spaces. The seminar takes place in cooperation with Oldenworx in Oldenburg. This means that we have a competent partner with many years of experience in the field of occupational safety, where we can simulate practical situations in a modern training centre. The content includes the basics of occupational safety according to the ArbSchG, BetrSichV, ArbStättVO, correct ventilation and the effect of nitrogen gases and oxygen deficiency or excess on the body.
