CRT-400 Cell Resistance Tester



The Cellcorder CRT-400 Cell Resistance Tester was specially designed to strictly comply with IEEE standards for testing batteries.
When a battery is tested, the measurements will be affectedby several factors.

» Online tests are subject to ripple(AC noise)from the charger or inverters.

» Batteries have a natural capacitance that will influence the accuracy of the reading

» The size of the test current directly relates to the accuracy of the measurement.

Advantages and Features

» Measures and records the three critical parameters:cell voltage and internal battery resistance as will as intercell resistance.

» Patented Internal Resistance measurements detect failing cells before they become a problem

» Blue tooth Capable - audible voice status during testing and data transfer to your PC

» USB Flash Drive - easy data transfer to your PC

» Battery Analysis Software identifies problem cells, creates reports and archives data

» IrDA allows wireless communication with PC and the DMA-35N Hydrometer

» Tests batteries from 0-16V

» Includes new battery test clamps with multiple jaw options

» Lighted, interchangeable spike probes with test status


 CVR+  Cell Voltage Recorder Plus


The CVR+ cell voltage recorder by Alber directly measures and records cell float voltage, uploads temperature and specific gravity (SG) measurement data from a DMA-35 or DMA-35N digital hydrometer, and downloads data to a computer running the Alber Battery Analysis Software (BAS). It was specially designed to strictly comply with IEEE standards for testing batteries. You'll save by taking and analyzing more readings in less time.

The high contrast 160 x 128 pixel graphical OLED color display shows menus and test results. A fully charged CVS+ can test for 15 hours, and isolated operation helps ensure safety and makes the CVR+ easy to move around.

The CVR+ displays cell float voltage, temperature and SG readings, charts and graphs on the color display. Test data quickly transfers to a computer, where Albér Battery Analysis Software analyzes battery state of health. An optional compatible hydrometer lets you transfer specific gravity and temperature data using the IR port or RS‑232 cable. You'll find that the CVR+ is one of the easiest ways to perform battery maintenance.

Evaluate as You Test

A major advantage of the CVR+ is being able to immediately view an analysis of the data being collected by providing statistical and graphical analysis of voltage, SG and temperature data during testing. The on‑site technician or engineer may simply pause at any time and view a graph or analysis of the data. The CVR+ makes testing and analysis easy and immediate, before you've left the site.

Accurate Data in a Fraction of Time

The CVR+ performs without the need to disconnect the battery from service. Use the CVR+ on a single cell or multicell modules. The unit stores up to eight strings of 256 cells, which lets the user collect a considerable amount of data before having to transfer it to a storage device or computer. An optional standard Flash drive allows virtually unlimited data storage. After testing, transfer data to a computer via the Flash drive, IR interface or USB cable. Alber Battery Analysis Software analyzes test data, displays results in graph or tabulated formats, and saves and prints reports. You may export reports in ASCII, Excel® or comma-delimited format so other programs can generate customized reports.

System Features

Plug 'n' Play USB Connection. The CVR+ offers Plug 'n' Play configuration of parameters and data. Simply connect the CVR+ to a computer and the software automatically extracts the data and uploads new parameters. This greatly simplifies data transfer and CVR+ configuration.

Float Voltage Readings. The CVR+ measures the voltage applied during full float operation. The voltage range covers all cells or modules up to 20 volts, with accuracy to four full digits.

Auto Ranging. The CVR+ features automatic voltage range selection.

What's Available. The CVR+ comes with voltage test leads, USB cable, RS‑232 cable, carrying case with belt strap, and BAS data trending and analysis software. An optional Flash drive, hydrometer, and printer are available.


DMA-35 Series Digital Hydrometers

Measuring specific gravity and electrolyte temperature has always been a time consuming, messy chore requiring two technicians: one to take the readings, the other to write down the data. Now, one technician can both measure specific gravity and temperature and record the data more quickly than with other conventional methods.

  • DMA-35 - The Anton-Paar DMA-35 is a handheld, stand-alone digital density meter suitable for use in demanding industrial environments. Simply press a lever and, within seconds, the temperature, density, specific gravity, or percent concentration of the sample is displayed. To save the data, press a button; up to 1,024 data points may be stored in the instrument.
    Weighing in at 10 ounces, the DMA-35 digital hydrometer won’t tire you out, no matter how many samples you must measure. And the DMA-35 delivers up to 90 hours of service on two alkaline 1.5 volt AAA batteries.
  • DMA-35/W - This version of the DMA-35 includes a certificate of calibration traceable to the NIST.
  • DMA-35-CRT - The DMA-35-CRT includes a CRT module used for data transfer to a PC or an Alber Cellcorder. It includes both an infrared interface for communication with the new CRT-400 and CRT-300 Cellcorders and a serial interface for a PC or the CLC-200. PC software is included with this model.
  • CRT Module Only - This is the CRT module only, described above, and does not include the DMA-35.
  • Case for above - Carrying case for the above models.
