Portable and Handheld Instruments

Portable and handheld test instruments like the current clamp probe and portable power meter are important parts of the field technician or engineer's toolkit. This is due to their flexibility, ruggedness in harsh environments, and varied functionality to handle anything from simple measurements to power quality analysis and pressure calibration. They are able to log data quickly to internal memory, as well as perform quick measurements for easy troubleshooting of industrial field equipment. Often times, it is not only impractical but cost-ineffective to bring high-end small handheld instruments onto the field where such precision is not warranted or needed. Portable test equipment is ideal for closing that needed gap. 

The wide variety of our DMM line provides the customer with different functions and accuracy depending on the requirements.

  • Calibrators for full spectrum of commonly measured signals in plant operations 
  • Trusted reference for verifying industrial instrumentation

Power quality analyzers combine the best features of a power meter with an energy panel meter, allowing them to monitor not only multi-phase power systems, but also track anomalies in the power system. 

  • 16 models of clamp-on testers
  • CL Series- AC, AC/DC, leakage current clamps, mini clamp meters
  • RMS, Mean, Temperature, frequency, and recorder output clamp testers
  • Yokogawa precision instruments including standard resistors and decade resistor boxes
  • For calibrating and monitoring and measuring DC current
  • Yokogawa analog and digital insulation testers
  • Several built-in voltage source ranges and resistance measurement ranges
  • Predict problems for preventative maintenance

Our Earth Ground Testers provide simple accurate measurement of earth resistance.

Our Digital Thermometers come in single function or two channel multi-function styles.

  • Accessories for digital multimeters
  • Voltage and current transformers
  • Clamp-on current probes
  • Selection of test leads

Accessories for Calibrators.

Out meters accessories, including shunts, allow instruments to measure current by reading the voltage drop across these resistors.


This application brief goes into how an insulation tester such as the MY600 can be used to maintain the integrity of magnetic flow meters. 


Preventative maintenance is crucial to maintaining reliable plant operations and reducing costly downtime. As electrical cables are found everywhere in industrial plants, insulaiton testing is one of the many active measures used in this type of periodic equipment validation. Insulation testers ensure the integrity of electrical cables by measuring the quality of the conductivity state. By diagnosing insulation quality early on, you can prevent harmful leakage currents from destroying nearby equipment or harming your personnel. 


After a disastrous 2009, the large publicly held test companies enjoyed booming business in 2010.
