The VOXiWatch II series continuous gas monitoring system is specifically designed for detection of H₂S and LEL (combustibles) around temporary workover rigs. VOXiWatch II uses our MP883 two-channel controller in NEMA 4X enclosure, outfitted with transmitters for 1 or 2 electrochemical H₂S sensor(s), or 1 or 2 catalytic bead LEL sensor(s), or one each of H₂S and LEL. All cable connections are protected by rugged strain relief in an explosion proof enclosure that includes a convenient mounting bracket. The transmitters are equipped with splash/mud guards and are on 25-ft cables. The 50-ft power cable comes with battery clamps for connection to a user-provided 12-24 VDC battery. The VOXiWatch II enclosure includes horn and strobe assemblies. Also included are Modbus® RTU, common or individual channel relays, and large easy-to-read color display.
