12bit MSO's 40 Mhz to 100 GHz, Probes, Series Network & Logic Analyzers

  • 1000V AC/DC; 10A AC/DC (with test leads and current jacks); resistance to 50 MΩ; capacitance to 10,000 μF, frequency to 100 kHz; temperature from -40 ℃ to 400 ℃
  • Robust, fast and accurate with manual and automatic ranging, Display Hold, Auto Hold, and Min/Max-Average recording
  • Backlit digital display, analog bar graph, and built-in temperature measurements with included thermocouple.


The ideal test tool for maintenance, troubleshooting and performance testing of individual stationary batteries and battery banks used in critical battery back-up applications

  • Key measurements – Internal battery resistance, dc and ac voltage, dc and ac current, ripple voltage, frequency and temperature.
  • Sequence measurement mode – Automatic or manual sequence testing of battery strings with automatic measurement storage including voltage, resistance and temperature (with BTL21 intelligent test probe), eliminating the need to press a button each time a measurement needs to be saved.
  • Comprehensive logging – All measured values are automatically captured during testing and can be reviewed on the instrument before downloading for on the-go analysis.


  • Reliable, repeatable, accurate device for checking bearings and overall vibration
  • Features innovative sensor design that minimizes measurement variations caused by device angle or contact pressure
  • Provides consistent data quality at both low and high frequency ranges
  • Offers four-level severity scale to assess urgency of problems and bearing condition


These three units beat every other comparable dry-well in the industry in performance, size, weight, convenience, ease of calibration, software, and price. In addition, the heating and cooling rate of each of these dry-wells is adjustable from the front panel, thermal switches can be checked for actuation testing, and multiple-hole inserts are available for a variety of probe sizes.
Hart dry-wells are easy to calibrate. You don't even have to open the case. This means less maintenance costs and less down time when they do need calibration.
Our Interface-it software lets you adjust set-points and ramp rates, log dry-well readings to a file, create an electronic strip chart, and perform thermal switch testing with data collection. The software is written for Windows and has a great graphical interface. Regardless of whether you want basic software or a completely automated calibration system, we've got what you want. Read about all our great packages starting on page 80.
Every dry-well we ship is tested at our factory, and every unit comes with a NIST-traceable calibration. There's no extra charge for the report, because we consider it an essential ingredient in our quality program. You shouldn't have to pay extra for calibration procedures we perform anyway.
