The Columbia AC/DC Clamp-On Tong Test Ammeters (now manufactured by Weschler Instruments) measure AC or DC current instantly and accurately simply by encircling the conductor with the jaws and closing them. A clear accurate reading instantly registers on the scale. (read more)

HOYT Instruments are designed for the extremes of MARINE ENVIRONMENTS. Very popular for marine applications, the CK-910/920/and 930 Series panel meters are low cost and have 5% accuracy. (read more)

The Laureate Model DC Digital Voltmeter & Ammeter is a UL-listed, 5-digit panel meter with 0.01% full-scale accuracy and read rates up to 60/sec. Such high read rates are ideal for peak capture, alarm and control, and real-time computer interface. The Laureate DC is ideal for use with external current shunts, which typically produce 50 mV or 100 mV at their rated maximum current. (read more)

If you are looking for something cost effective that can be used for most applications, then analog is the best choice. These meters require no power, are available in custom scales and will monitor from PLC or Transducer. (read more)

Thermovolt shunts offer the highest quality possible at the best possible price. What makes Thermovolt unique is the use of manganin rods, which are silver soldered to copper terminal blocks and nickel plated. Standard blade shunts cannot compare to Thermovolt's price, quality and performance standards. (read more)

The Laureate Model RMS is a UL-listed, 4-1/2 digit, true RMS panel meter which provides 0.15% ± 1 count accuracy for AC voltage or current signals from 10 Hz to 10 kHz. It is suited for AC applications where there is considerable distortion of current waveforms from nonlinear loading. The input is AC coupled to read only the AC component, such as ripple on a power supply. (read more)

The RPS-401A-80P analog ultrasonic sensor is mounted in a PVC barrel housing and is completely self contained. It is powered by 20-30 VDC and is reverse polarity protected. It also has a narrow beam angle, which enables it to get into tight places. A flat target can tilt up to 10 degrees and still be detected. (read more)

The RPS-401A, RPS-426A analog ultrasonic sensor is mounted in a barrel housing and is completely self contained. It is powered by 20-30VDC and is reverse polarity protected. It also has a narrow beam angle, which enables it to get into tight places. A flat target can tilt up to 8 degrees and still be detected. (read more)
