Three Legs are Better Than None

When it comes to providing a stable platform for a thermal imager, it’s hard to beat a tripod. As thermal imagers have gotten smaller and lighter, many thermographers have all but forgotten this once requisite accessory that can help provide better quality data while reducing stress.

For many PdM applications that require still images only, using a thermal imager in a hand held configuration is usually sufficient. However, for applications that require imaging from a fixed vantage point over extended periods of time or where videotaping is desired, a tripod can be an invaluable accessory. When selecting a tripod there are several things you should bear in mind:

1. Be sure to select a tripod capable of carrying the weight of your imager.

2. Tripods should connect directly to the imager via a 1/4” x 20 set screw. Tripods with plastic quick releases should be avoided as they are subject to wear and can cause an imager to suddenly fall.

3. Tripods with sturdy hardware and locking systems are more secure and generally last longer than inexpensive models.

4. Fluid head tripods are preferable since they provide smooth motion for videotaping and are less likely to drop an imager if the head is left unlocked.

When carrying a tripod be sure to maintain a safe distance from energized electrical equipment or moving machinery.
