Gossen Metrawatt M273S Multifunction Installation & Motor Testing Multimeter

The Gossen Metrawatt M273S METRAHIT IM XTRA BT is a high-performance multifunction test instrument combining an insulation resistance tester, milliohm meter, TRMS digital multimeter and short-circuited coil tester within a single portable platform.

Designed specifically for maintenance, diagnostics and commissioning engineers, it provides the functionality required to evaluate electric motors, drive systems, hybrid and electric vehicles, industrial automation equipment and power installations.

Unlike a standard multimeter, the M273S combines insulation testing, milliohm measurement, motor winding diagnostics and advanced TRMS measurement in a single instrument. This reduces the number of test devices engineers need to carry while providing specialised functionality for electrical maintenance, motor testing, automation diagnostics and EV servicing.

Features:

• Insulation resistance testing up to 3.1GΩ with selectable test voltages of 50V, 100V, 250V, 500V and 1000V
  
• Integrated DAR (Dielectric Absorption Ratio) and PI (Polarisation Index) insulation analysis
  
• 4-wire Kelvin milliohm measurement with selectable 200mA or 1A test current
  
• 2-wire low resistance measurement with 200mA test current complying with EN 61557-4
  
• TRMS AC, AC+DC voltage and current measurement up to 100kHz bandwidth
  
• Current measurement from 10nA to 1A
  
• Capacitance, frequency, duty cycle and RPM measurement
  
• Temperature measurement using Pt100, Pt1000 and Type K sensors
  
• Short-circuited coil testing capability when used with optional COIL Adapters, not supplied
  
• Integrated Bluetooth interface
  
• Colour TFT graphic display
  
• Internal memory for approximately 300,000 measurements
  
• CAT III 1000V / CAT IV 600V safety rating
  
• IP52 rated housing for field use
