Name: AirLink 6940XP
Brand: RKI Instruments

Overview

The RKI AirLink 6940XP series ambient air multi-gas detector is a versatile assembly that uses up to four electrochemical, PID or low-power infrared sensor elements to detect a variety of gases. Wireless, battery power (3.6 V/76 Ah) with 900 MHZ or 2.4 GHz radio options. Magnetic switches allow for non-intrusive calibration while in the field as well as full system settings and diagnostics. Mounting is made easy and mobile using the optional wheeled stand.

The AirLink 6940XP represents the latest leading edge wireless technology in fixed gas detection today.
