Wireless key MTICWD-200 Guardian 7000

Quick Answer: The Wireless Key MTICWD-200 Guardian 7000 is a plug-in wireless module, shaped like a USB stick, listed for Guardian 7000 hotplates, stirrers and hotplate stirrers. The Guardian 7000 wireless key provides the radio link that the range uses for monitoring and control away from the bench.

What the Wireless Key Does

The Guardian 7000 range from OHAUS is the connected member of the Guardian family, promoted with wireless features for checking and adjusting a running unit without standing next to it. Hardware for that link comes as a small plug-in module rather than being built into every unit, and this listing is for that module under the part code MTICWD-200.

The listing photograph shows a white plastic key with a standard USB-A plug at one end, a small status light and the OHAUS logo printed on the body. It is a module, not a standalone device: it works only when plugged into a Guardian 7000 unit and paired with the software or display the range uses. The listing does not state the radio standard, the range or the software version it needs, so the unit manual is the place to check how it is set up.

Remote access is useful for long heating or stirring runs, but it does not replace lab safety rules. Heated reactions that could boil dry or overheat still need a person nearby, and many labs require that unattended heating is approved and labelled.

Care & Handling

• Plug the key in with the unit switched off, following the unit manual
• Keep the key away from spills and heat; it is not sealed against liquids
• Store it in a labelled bag with the unit’s accessories when not fitted
• Update unit software only as the manual describes

Applications
