Specification callouts to check before you buy
Match the tester to the task - field service and lab work place different demands. Below is a compact comparison to speed selection:

|---|---|---|
| Voltage range | Up to 5 kV for motors and insulation systems | 250 V-1 kV for component-level and student labs |
| Accuracy & display | Robust, clear LCD; basic PI routines | Higher resolution, logging preferred |
| Accessories | Heavy-duty leads, clip sets, calibration caps | Benchtop adapters, low-voltage ranges |
If you need help selecting models that fit your institution or workshop, use our Shop by Brand page to compare offerings and confirm compatible accessories.
Accessories and bundles we recommend
- Heavy-duty test leads with shrouded probes for field insulation testing
