  • Natural Electromagnetic

    EM - Alpha Lab, Inc.

    The TriField Natural EM Meter was designed to do field measurements for special research. It detects changes in extremely weak static (DC or "natural") electric and magnetic fields, and signals with both a tone and the movement of a needle-type gauge if either the electric or magnetic field changes from previous levels. A radio and microwave detector is also included, which reads radio power directly. Because man-made AC electric and magnetic fields are very common and could interfere with readings of static fields, the meter has been designed to ignore AC fields. Normal construction materials don't block magnetic fields, so the meter can be placed indoors and will work equally well, and due to the built-in tone, it can be used in the dark, and will sound the tone at whatever level of field the user sets. Model 1 operates on a standard 9-volt battery, and Model 2 runs on a 9-volt battery or an AC adapter (both included). Model 2 has an input jack for an optional high-sensitivity magnetic coil.

  • Ultrasonic Proximity Sensors and Fill Level Sensors

    Hoffmann + Krippner, Inc.

    Ultrasonic sensors – by using high-frequency sound waves to detect the position and distance of objects – excel in industrial environments and applications that can frustrate other sensors. Ultrasonic detection can monitor objects whose surface structure, material, or color/translucence might distort the readings of other sensors. Even miniscule objects can be measured. Regardless of application – ultrasonic distance sensor, ultrasonic level sensor, and more – measurements can be captured with fine-tuned precision. The full line of Hoffmann + Krippner ultrasonic sensors have been exceptionally engineered and designed to accommodate an enormous array of needs, scenarios, and situations. In all cases, the exacting accuracy and ease-of-use of our ultrasonic sensors help users to achieve efficiency gains and streamline processes. Further, our sensors include popular and widely used designs that have been discontinued elsewhere. If your organization already uses ultrasonic sensors, we likely have the same sensors available for replacement parts and new objects. Please see the cross-reference charts at the bottom of this page for more information.

  • Tone & Probe Kit Cable Tracer

    PR-608/608A - Pansco, Ltd

    The Net Toner & Probe Kit is a practical telecom and network installation, maintenance and troubleshooting tool. The kit helps you locate and identify wires, pairs and cables. The Net Toner has the unique features of enhancing talk battery power supply to allow communication over inactive pairs, using telephone test sets. It provides two able tones which allow you to trace cable and locate faults for troubleshooting both voice and data circuits. It also tests cable continuity and can determine line 1 and line 2 polarity and voltage in data and voice lines. It features a tone signal, two alligator clips, & 4-conductor (RJ12) modular cable to test telecom, cats cabling, coax cable and bare wires. In continuity mode, when a short circuit is detected an audible sound will be heard (PR-608A only). The short circuit test function are only applied to line 1 4/5 when using the RJ12 plug cable. The tone generated by the Net Toner can be easily traced by the Net Probe or any other commercial probe.

  • Compact Receiver

    UCR411a - Lectrosonics, Inc.

    The UCR411A receiver provides professional performance and a versatile feature set in a compact design for field and location production. All settings are made from the front panel with a powerful LCD interface, making the unit ideal for use in Quad Paks, on sound carts, in portable bags and in rack mount multi-couplers. To alleviate interference problems in an increasingly congested RF spectrum, an RF spectrum analyzer is built into the receiver. The receiver tunes across its 25.6 MHz tuning range and records RF activity with markers on the LCD screen. Finding clear operating frequencies is a quick, simple process. The UCR411A is compatible with all 400 Series Lectrosonics wireless transmitters (and some other transmitter types) and can be powered with internal 9V batteries or external DC.
