Esders GmbH
About
Esders GmbH, headquartered in Haselunne, Germany, manufactures precision measurement and testing technology for gas, water, and wastewater pipeline infrastructure. The company's flagship smart memo is a multifunctional electronic pressure measurement case supporting up to five external EDS2 sensors with menu-guided test procedures compliant with EN 805 for drinking water, EN 1610 for sewage, and VIAG G22/23 for gas standards, featuring 4G LTE data transfer, GPS positioning, and automatic pressure drop testing. The companion MPP 30-30 test pump provides fully automatic water pressure testing per DVGW W 400-2 with 30 bar maximum outlet pressure, 30 liters per minute delivery, and adjustable test pressure in 0.1 bar increments with frequency converter speed control. For water network monitoring, the DruckLogger DL4 pressure logger measures up to 25 bar with better than 0.1% accuracy, IP68 protection, and six-month lithium-ion battery life, screwing directly into hydrant connections. The EDS2-V digital flow meter connects to the smart memo for automatic volume recording during pressure drop tests, covering 4-160 liters per minute. On the gas safety side, the OLLI gas warning device provides ATEX-certified confined space entry clearance measurements detecting CH4, C3H8, O2, CO, CO2, and H2S per DGUV Regulation 113-004, with an OLLI H2 variant for hydrogen infrastructure and an OLLI Tracer Gas model. The HUNTER family includes the standard HUNTER gas leak detector with 10 ppm quick test, the Laser HUNTER for laser-based leak detection, and the HUNTER SF6 for SF6 detection. The Opgal EYECGAS 2.0 OGI camera visualizes methane emissions from a distance for LDAR campaigns and EU Methane Regulation compliance. The TONI family covers pressure, leak, load, and serviceability testing for indoor gas installations, drinking water, heating, and cooling systems. Esders also provides the Pi NOTE GIS software for underground gas pipe inspection data management per DVGW G 465, the Esders Connect Portal for paperless documentation and LTE/GPS data transmission, and operates Esders Pipeline Service GmbH in Bielefeld for trenchless pipe rehabilitation and high-pressure cleaning of sewer and landfill pipes.
