Portable Battery Test Equipment
Alber Cellcorder CRT-400 Cell Resistance Tester
The Cellcorder CRT-400 is Alber's newest handheld cell voltage and resistance tester. This exciting addition to Alber's test, diagnostic and trending products measures and records cell float voltage, internal cell resistance, and intercell connection resistance.
Another exciting feature is a new USB port and Flash drive that allows quick transfer of data files to a computer. Using the Alber Battery Analysis Software, test results can be displayed and analyzed to determine battery state of health. The Flash drive also doubles as an interim storage device until test data is saved permanently.
The Cellcorder CRT-400 comes with a 256M Flash drive, resistance and voltage test leads, carrying case, AC charger, and data trending and analysis software. An optional printer is available.
Anton Parr DMA-35 Digital Hydrometer
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.
DMA35 - The Anton-Paar DMA35 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. (P/N 2900-042)
Weighing in at 10 ounces, the DMA35 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.
DMA35/W - This version of the DMA35 includes a certificate of calibration traceable to the NIST. (P/N 2900-042WC)
DMA35-CRT - The DMA35-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. (P/N 2900-044)
CRT Module Only - This is the CRT module only, described above, and does not include the DMA-35. (P/N 2900-043)
Capacity Test Systems
BCT-2000 Battery Capacity Test System
The best proven method for determining whether a battery will perform is to test it under load conditions. Proper load testing is the only way to determine where the battery resides on its expected life curve. The Albér BCT-2000 capacity test system will test any battery in service today.
Load testing is essential for any storage battery system that protects equipment or a critical service. Because the battery is almost always the least reliable component, load testing with the BCT-2000 should be done on a regular basis to ensure reliability. The BCT performs battery load tests using load banks or, in some cases, the actual system load.
The BCT-2000 performs a capacity test using a programmed, constant current or constant power load. This test predicts reliability and remaining battery life before replacement is necessary.
An integrity test, using a high current momentary load, lets you identify weak cells and conduction paths.
Data Acquisition Module and Data Logging Unit
The BCT is a combination load control and data logging system consisting of a data acquisition module and a laptop computer data logging unit. The data acquisition module acquires all cell voltage, overall string voltage, and current readings and is available in 128 cell and 256 cell versions. The computer data logging unit displays the programming parameters for the test.
The BCT's proprietary interface circuits and custom software control all standard Albér continuous and momentary load units. The standard BCT-2000 can be programmed to apply a constant current or constant power load on any battery string up to 600VDC. During a load test, the system records overall voltage, load current, and up to 256 cell voltages. Programmable alarm levels warn of low voltages and can automatically pause testing before any cell reaches reversal or an unsafe state.
Continuous Load Units
The Continuous Load Unit (CLU) provides the load during a capacity test. It may be used with the BCT-2000, the BDS monitor, or stand-alone with the Manual Control Box. Load units may be ordered in standard configurations or built to individual customer needs. Configuration and design of the resistive elements let the user adjust the load in small increments through the entire test system capacity.
The load units may be used with any Alber data logging and load control unit, or stand-alone. Together, the two instruments create a system capable of providing a maximum range of configurations tailored to customer needs.
Each CLU is housed in an aluminum enclosure with expanded metal sides and top for excellent ventilation. This enclosure is mounted on lockable, hard rubber casters for portability. The conservative rating of the load resistors and the fan cooling system keep the frame from reaching excessive temperatures.
All continuous load devices are rated in constant current, but can be used for constant power testing when used with the AlberBCT-2000 battery capacity test system. Standard units are available from 21VDC to 270VDC. Custom load units for voltages outside this range can be readily designed and manufactured.
