    Ni-H battery can work continuously for more than 10 hours without recharge. The TDS-100H has also a built-in data-logger, which allows storage of 2,000 lines of data. The stored information can be downloaded to a PC through its RS232 connection port. The TR- 100H also provides digital output such as frequency output or pulsed totaliser output.
