The HHM98P multifunction clamp-on
meter provides high accuracy and
reliability in a low-cost, portable
package. The built-in AC clamp
makes this meter ideal for
troubleshooting electric resistance
heaters and other plant electrical
systems. In addition, the HHM98P
effectively measures current from
3 to 1000 A.
