Tinytag Talk 2 Voltage Logger - TK-4703

Description

The TK-4703-PK Tinytag Talk 2 data logger is a compact data logger that is suitable for monitoring DC voltages up to 2.5vDC. The TK-4703 has been specifically designed as a low cost data logger for monitoring small DC voltage from various sensors including current clamps, pyranometers or other low voltage sensors. The 50µV resolution of the DC input range provides a much higher accuracy for low voltage output sensor and the compact size makes the logger ideal for space restrictive applications. This logger is very popular building condition monitoring and academia. The lightweight 35mm film canister case is only IP30, so will require additional protection if used in a harsher environment.

  • Opaque 35mm film canister case
  • 2 user programmable alarms
  • Delayed start option (up to 45 days)
  • User replaceable battery

Popular Applications

  • Battery level monitoring
  • Customised data logging with suitable external sensor
  • Building condition monitoring
