Calibration using solution standards

  • Arrow keys allow fast setting to calibration standards
  • Calibration data is saved even when the unit is turned off
  • Instant-response probe and solid-state thermistor provides precise readings
  • Temperature compensation permits readings to be automatically referenced to the international standard of 25°C or user may set programmable temperature coefficient

To assure accuracy, an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

Please note: The aforementioned A2LA accreditation belongs to the manufacturer, not Thomas Scientific.

    This product is described as simple and easy. However the basic information on how to calibrate or switch modes is not provided. Therefore operating this probe can be frustrating without a user manual.
