MegohmMeterStore.com offers two kinds of 1000V megohmmeter - handheld megohmmeters and larger field megohmmeters packaged into durable cases.

For general-use handheld insulation resistance testing, check out the AEMC 1026 1000V megohmmeter or the value-price Reed C-360. Fluke fans can check out the Fluke 1503 1000V megohmmeter or the Fluke 1507 with more test voltages. Alternatively, consider the multi-functional Fluke 1577 and Fluke 1587 multimeters with insulation testing capabilities.

For rugged field use, try the AEMC 1050 or its datalogging brother, AEMC 1060 or the AEMC 1250N handcrank megohmmeter that doesn't require batteries.
