Featured Product
  • WESCHLER Transducers

    Use Weschler CTs, PTs and shunts as the front end to a panel meter, transmitter, data logger or tester. AC Current Transformers are available in sizes from 1 to 200VA, currents to 5000A and windows up to 8".  Split core models simplify installation on existing lines. Potential Transformers reduce high AC line voltages to a level compatible with most meters.  DC Ammeter Shunts handle up to 10000A with an output of 50 or 100mV full scale.  Other current, voltage, frequency & power transducers also available.

  • WESCHLER Large Bargraph

    A Large Edgewise meter is the newest model in the Premo family of smart Bargraph products.  The BD101P includes a 6 digit alpha-numeric display, a 10" 101 segment tricolor bar and 6 setpoints.  A wide range of inputs and extensive computation capabilities make this a flexible product for display and control. 

    Enhanced table calibration is ideal for tank level, square law & other non-linear measurements. The BD101P is easily interfaced to a network via Modbus serial or Ethernet. The 12" case fits a Bailey draft gauge cutout.     More

  • TEXMATE Meter/Controller

    Measure and display three system signals with the DI-503 DPM/Controller.  Mix inputs for V, A, frequency, counts & transducers in one meter.  Cross channel math & internal computations provide flexible monitoring. Add relays & analog outputs to control external processes.   96x48 DIN case has red +/or green digits.  RS-485, Ethernet & Modbus interfaces available.    See more Texmate DPM  models

  • MEGGER Handheld Micro-Ohmmeter

    The MOM2 is a revolutionary way to measure the resistance of circuit breakers, busbars and other high current links.  It is portable & battery operated, but delivers up to 220A test current.  Measurement range is 1µΩ to 1000mΩ.  The DualGround test method, where the test object is grounded on both sides during the test, provides a safer, faster & easier workflow.  Up to 190 test results can be saved for later download to a PC via a Bluetooth link.  The MOM2 is CATI rated for substation and industrial environments.   More Info       Other Megger Products

  • YOKOGAWA Process Meter/Controller

    The ProPlus Series advanced meters have one or two inputs and two large 6-digit displays.  Measure level, temperature, pressure, flow, rate and other process signals.  Includes extended math functions (+, –, ×, /, avg, ratio, sqroot, min, max...).  Modbus serial communication standard.  mA retransmit & relay outputs optional.   AC & DC powered models.  1/8 DIN case with NEMA4X front.  UL Listed.   See more

  • LASCAR USB Data Loggers

    Lascar USB Data Logger from Weschler Instruments

    These miniature data loggers measure and store up to 32000 readings.  Plug into the USB port to set the sampling rate. Then unplug to log  independently.    Alarm levels and start/stop times are also programmable.   Plug back into the PC to download stored data for viewing and analysis, using the free EasyLog software.  Models available to record  temperature, humidity, voltage or current.  The LCD display is optional.   More info
