Quick Overview

UNI-T UT233 Digital Power Clamp Meter Details

Versatile, strong and capable of being used absolutely everywhere from domestic environments to industrial applications, the UNI-T UT233 is a great digital clamp meter for use by any practising electrician.

By use of the devices’ jaws (which can fit conductors with diameters of up to 50mm inside) it is possible to measure AC current levels across four ranges: 40A, 100A, 400A and 1000A. In addition to current measurements the UT233 can also measure AC voltage up to 600V, frequency from 20Hz-500Hz, active power from 0.01KW-600KW, apparent power from 0.01KVA to 600KVA, reactive power from 0.01KVARr to 600KVAr, phase angle from 0 to 360° and active energy from 1-9999KWh.

Both autoranging and true-RMS, the UT233 ensures that all testing is carried out with a high degree of accuracy at all times. It also includes a selection of useful advanced features such as 10000 count display, auto shut down, MAX/MIN and data hold functions.

The UT233 is EN 61010-1, EN 61326-1 and EN 61010-2-032 compliant. It is also CAT II 600V and CAT IV 300V safety rated.
