The ISW8300 and ISW8350 are excellent value, both offering three and single phase power analyzing, power meter / watt meter capability.  Three phase power meters / watt meter are a necessity when several electrical measurements need to be recorded during testing, with one set of input connections.  Typically, three phase power meters are important when accurate watts measurement is necessary for certification and traceability. In addition to power measurement (watts), reactive power (VAr), apparent power (VA), voltage rms, current rms, power factor, can all be viewed with ease. All Powertek power meter / wattmeters simply connect between the ac supply and the load, various current transformer and shunt options allow measurement with any level of current amplitude. Typical three phase watt meter applications include appliance testing like generators, electric stoves, heating, air conditioning, pumps, fans, electronic lighting and motor controllers .  All our  power meters are equipped with safety terminals (4mm/banana) along with optional "breakout" boxes and clamp probes for fast and safe measurement.  The new ISW8300A has increased bandwidth and dc measurement capability.
