OI-6940 ST

The Otis Instruments, Inc. OI-6940-ST is a two-wheel stand engineered specifically for use with the OI-6940 Notis Quad Sensor Assembly.



The unique hand cart design of the OI- 6940-ST enables the robust OI-6940 sensor assembly to be easily transported while in the field. Pre-mounting of the OI-6940 sensor assembly onto the stand eliminates the need for on-site mounting. Simply place the battery-powered WireFree OI-6940 sensor assembly and stand in the desired location and power on the device.

Features and Benefits

  • Two-wheel hand cart design allows the 23 lb. OI-6940 sensor assembly to be pushed or pulled, not carried
  • Eliminates the need for placement in an area with a pre-existing structure strong enough to support the OI-6940 sensor assembly
  • No mounting tools or hardware necessary for setting up the mounted OI-6940 sensor assembly on location
  • Pre-mounting the battery-powered WireFree OI-6940 sensor assembly reduces installation and setup time while in the field
  • Stackable design for compact storage of pre-mounted OI-6940 sensor assemblies
