Portable Multi-gas Detectors – Polytector III G999S Polytector III G999S – Versatile gas detector The Polytector III G999S expands the reliable G999 series by a multi-gas detector with hybrid sensor for applications using natural gas or hydrogen. The sensor, which was specifically designed for this purpose, uses semiconductor (SC), catalytic combustion (CC) and Thermal Conductivity (TC). This combination allows a single sensor to seamlessly detect methane in measuring ranges from 0 to 10,000 parts-per-million (ppm), 0 to 100 % of the lower explosion limit (LEL) and 0 to 100 % volume as well as...

Portable Multi-gas Detectors - Polytector III G999S {p[fj}l| What makes the G999S unique is its hybrid sensor which is available with either two or three sensor elements and measuring methods. On the two-element version (CC/TC), you can switch between explosion protection mode and HI% measurement mode (CH4 or H2). On the three-element version (CC/TC/SC), you will additionally have the sniffer and leak detection mode (CH4 only) available. Depending on the measuring task, either all of the sensor elements or just individual ones will be active. The hybrid sensors for the G999S are optionally available...

Safety when working and measuring The G999S is suitable for use in biogas plants. In pipeline construction and for energy suppliers (natural gas and HCNG), its versatility is an advantage for personal protection since it warns its users of dangerous gas concentrations in the ambient air or for clearing shafts and ducts before entering them. The gas detector can also be used to discover even the smallest CH4 leaks as well as for gas analysis in the high-percentage range. The thermal conductivity sensor can also be used in applications where HI% measurements with an infrared sensor are not possible,...

Portable Multi-gas Detectors – Polytector III G999S Charging, testing and adjusting The NiMH battery of the G999S has enough power to last a whole working day, even with heavy use. To recharge the device at the end of your shift, simply place it in the charging tray which is powered either by a power supply unit or a 12 Volt plug. The daily bump test and its subsequent documentation according to DGUV information 213-056 (T021) and 213-057 (T023) can be performed automatically, quickly and cost-effectively by one of GfG’s test and docking stations. Choose between the TS888/999 and TX888/999 test...
