Tinytag Data Loggers: Robust Environmental Monitoring Solutions

The Tinytag range of data loggers has been designed and manufactured in the UK by Gemini Data Loggers since 1992. The range includes rugged devices designed for monitoring in industrial, manufacturing, process and engineering applications. Compact, accurate and versatile, Tinytags help ensure that conditions can be measured, recorded, analysed and validated.  Tinytags record:

  • Temperature
  • Relative humidity
  • Single and three phase power usage
  • Carbon dioxide
  • Low voltage
  • Current
  • Count inputs

Loggers are set up, and recorded data displayed in the Tinytag Explorer software, an easy to use Windows program. Results from separate logging runs can be combined for comparison and analysis, and data can be exported into popular desktop packages for use in reports and spreadsheets etc.

Choice of units

  • Standalone, network enabled or wireless devices
  • Dual channel loggers to simultaneously monitor two parameters e.g. temperature and RH
  • Rugged, waterproof and dustproof units
  • Units with displays showing current readings as well as recording data
  • Fully submersible, high temperature loggers
  • Range of accompanying thermistor probes, PT1000 very low temperature probes, and PT100 very high temperature probes
  • Voltage, current and count input loggers for connection to third party sensors for specialist applications

Case Study

Caparo Testing Technologies offers various metallurgical and non-destructive testing services to aerospace, oil and gas, and general engineering companies. Caparo is using two Tinytag View 2 data loggers each with a thermistor probe to help prove that the temperature of a waterbath is maintained at the correct tolerance level for corrosion testing of steels.

Recorded data is checked after a test period of 24/48 hours. If the waterbath has maintained the correct temperature within 2 degrees Celsius, no further action is taken. If any issues become apparent, the results are not reported and the waterbath is investigated.
