UEi DL389B True-RMS Clamp Meter
The UEi DL389B True-RMS clamp meter is widely used and works well for linear electrical loads. However, when the loads are nonlinear, like those of an adjustable-frequency drive, or semiconductors, they require the accuracy of a True-RMS meter like the DL389B PHOENIX: PRO+ to correctly measure the distorted sign-waves. In these situations a True-RMS meter will provide a correct reading on the distorted wave-form where an average-responding meter may result in error readings up to 40%.

UEi ATTPC3 K-Type Pipe Clamp Probe.
The UEi ATTPC3 is a clamp style K-Type thermocouple temperature probe with a temperature range of -40˚ to 250˚F (-40˚ to 121˚C). The UEi ATTPC3 is compact and easy to use and fits 1/4" to 1 1/2" pipes. With an improved strain relief comfort grip, the UEI ATTPC3 is an excellent addition to your tool kit.
