  • Digital Hydrometers / Density Meters

    SBS Storage Battery Systems, LLC

    SBS introduced the first digital battery hydrometer to the U.S. stationary battery market back in 1988. For the past 25 years, SBS has sold and serviced thousands of hydrometers and continues to provide the newest technologies in battery maintenance equipment today.Hydrometers (density meters) measure the specific gravity of a battery’s electrolyte. Based on the specific gravity, the user can determine the state of charge of the battery. Retaining these hydrometer readings and data over time is recommended by IEEE as part of any Battery Maintenance Program.

  • Field Strength Meters

    Precision Test Systems Ltd.

    The FSM series of field strength meters will measure the strength of a RF signal appearing at its input from +20 dBm to -110 dBm for wide bandwidth models and +10 dBm to -120 dBm for narrow bandwidth models. The RF strength will be displayed on an LCD display to an accuracy of ±3 dB over the entire 130 dB dynamic range. A matching field signal generator is also available to act as a signal source for propagation studies.

  • Flow Meter Sensors

    SPECTEC Innovative Sensor Solutions

    SPECTEC's RF flow meter sensors are active RF pickups driven by an external RF (carrier) signal conditioner. Together they complete an oscillating circuit. The output of this circuit is amplitude modulated when a ferrous, 316 stainless steel or aluminum object passes by the pickup coil. This change in modulation of the carrier frequency is converted into a square wave pulse by the signal conditioner for computing and/or further processing.

  • Extinction Ratio Meter

    ERM-202 - General Photonics Corp.

    The ERM-202 is a single or dual channel polarization extinction ratio (PER) meter. When used with a broadband source, it directly measures PER. Single and dual channel models are available. The single channel instrument can be upgrades to two channels version at a later date. By combining low noise circuitry with a high resolution stepper, the ERM series achieves a PER dynamic range of 50 dB.
