1It adopts the most advanced, reliable and stable sensor with high sensitivity, long service life and longterm use. 2Highly stable dedicated chip and professional placement technology ensure good consistency and high reliability. 3420mA analog signal, switch signal, and 485 digital signal is available for multiple system options. 4It is easy to use, the front and rear cover of the meter is opened, wiring, debugging and maintenance are very convenient for people to measure combustible gas. 5The combustible gas detector detects the ambient temperature at 20~60, fixed installation. Item Type: Combustible Gas TesterMaterial: Stainless SteelModel: WLKY-800Purpose: Gas DetectionWorking Voltage: DC24VOutput Signal: 4-20mA, RS485, Switching ValueMeasurement Accuracy: 5% FSEnvironment Temperature: -20~60Environmental Humidity: 10~95%RHResponse Time: 20~120SExplosion-Proof Grade: ExdllCT6Sampling Method: DiffusivityInstallation Method: Fixed InstallationHow to Use:1. Determine the installation height according to the specific gravity of the detected gas2. The shell should be well grounded with the grounding screw, and the inlet connector must be tightened3. If the detector is installed outdoors, a rain cover is required 1 x Combustible Gas Tester Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.
