Description

The OLLI is an explosion-proof, multi range measurement device for flammable & toxic gases and oxygen.
The device comes either in a diffusion version and can be equipped with an internal pump and pressure measurement. The well-known and easy-to-use operating concept with a menu navigation driven by two function keys and a ENTER button has been enlarged by an ESC/return button.

Manhole inspection

In the field of gas and water supply and sewage disposal, workplace monitoring and controlling the atmosphere in confined and enclosed spaces is a fixed and important part of work procedures according to DGUV Regel 113-004.
Before work can begin, it has to be ensured that there is no lack of oxygen and that the shaft atmosphere is free from harmful substances. Furthermore, it must be determined whether an explosive atmosphere can be ruled out. Especially for structures in the area of sewage disposal, a clearance measurement is mandatory.

Do you need a gas detector to inspect manholes? Then we offer you our OLLI, an effective gas detector with pump for combustible gases, toxic gases (H2S, CO, CO2) and oxygen.
According to the German Employer's Liability Insurance Association (Berufsgenossenschaft), these gas warning devices "[...] are an aid to hazard reduction by detecting the presence of [flammable and] toxic gases and emitting suitable acoustic and/or optical warnings." (Quote DGUV Information 213-056).

In one of our workshops, the participants are taught necessary technical knowledge to perform clearance measurement in accordance with DGUV Principle 313-002.

Data management

It was not so long ago that printing on thermal paper was a revolution on the construction site. As an environmentally conscious and future-oriented company, we want to do without paper and at the same time make your everyday work easier.

With Esders Connect the measurement data will directly be send to your office via our App for your smart phone or tablet – fast, paperless, digitally and DSGVO compliant. You have the option of specifying up to three e-mail addresses in order to send the completed test reports to them. The recipients also receive the GPS data for the exact localisation of the measurement. The administration is clear and can be accessed from anywhere at any time.
Esders Connect is browser-based, so no updates are required and you always have the latest version available.
