{"product_id":"rki-gx-3r-pro-gas-detector","title":"RKI GX-3R Pro Gas Detector","description":"\u003cp\u003eThe RKI GX-3R Pro is the world's smallest 5-gas monitor, built around four sensor slots: an interchangeable CO\/H2S combo or single-gas cell, catalytic LEL, electrochemical O2, and a 5th channel for HCN, NH3, NO2, PH3, SO2, or IR CO2. RKI offers dozens of factory-built sensor combinations — the configurations listed here cover the most common confined-space and toxic-gas pairings; other sensor combinations are available by quote.\u003c\/p\u003e\n\u003cdiv style=\"border: 1px solid lightgray; text-align: center; width: 100%; padding: 12px;\"\u003e\u003ca href=\"https:\/\/www.geotechenv.com\/pdf\/air_quality\/rki_gx-3r_multi-gas_monitors.pdf\" style=\"font-size: 15px;\" target=\"_blank\"\u003eSPECS\u003c\/a\u003e\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid lightgray; text-align: center; width: 100%; padding: 12px;\"\u003e\u003ca href=\"https:\/\/www.geotechenv.com\/Manuals\/RKI_Manuals\/GX-3R_Pro_Manual.pdf\" style=\"font-size: 15px;\" target=\"_blank\"\u003eMANUAL\u003c\/a\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eBattery runtime ranges from about 16 to 25 hours on lithium-ion depending on sensor configuration (3-hour recharge), with alkaline as a backup option.
