Product model:PGM-2400
-
Product type:Pump suction/diffusion type four in one combustible gas/oxygen/toxic gas detector
-
Product Description:QRAE II is a portable four in one detector that can detect multiple toxic and harmful gases, and can simultaneously detect combustible gases, oxygen, and toxic gases. QRAE II is compatible with both diffusion and pumping modes of operation, suitable for different application scenarios.instrumentCompact size, easy operation, built-in Chinese menu, more suitable for Chinese users. Humanized flip display design on the screen for easy observation.
