TV-4020 | External Probe | Temperature -40 to +125°C (-40°F to +257°F)

The TV-4020 monitors Temperatures from -40 to +125°C (-40°F to +257°F) using one of our range of thermistor probes, making it ideal for awkward to reach areas or where a fast response time is required.The unit has a display, and is tested to BS EN 12830 to meet the demands of frozen and chilled foods storage and transportation.

Tinytag Explorer is the Windows program used to configure Tinytag loggers and view recorded data. During set up, logger names, logging intervals and alarm settings can easily be chosen. Recorded data can be shown as a graph, table of readings or summary information.
Interface cables are used for connecting the logger to a PC for programming and recovering stored data.
Listed Below are several options for purchasing the required software and interface cable for the TGU-4020 Logger. The most economical package is the (SWPK7-USB) it includes both the Explorer Software (SWCD-0040) and the Interface Cable (CAB-0007-USB).

Understanding Calibration

During calibration data loggers are compared to a reference meter that has been calibrated in a UKAS (United Kingdom Accreditation Service) approved laboratory. Data Loggers for use with a probe are calibrated with the accompanying probe. The certificate lists the value recorded by the reference meter (the temperature or humidity at which the data logger was tested), the value recorded by the data logger and the error between the two readings (the certificate will also show readings before and after any adjustment made to the unit where appropriate). In addition to the reading information, calibration certificates also list the test method and the details of the equipment used to provide traceability back to national standards.

Calibration certificates do not have a period of validity; they are simply a statement of what the unit was reading when it was tested. That said, unless the application is particularly critical or demanding, most people get their loggers calibrated annually.

Even if you don't purchase calibration certificates, we guarantee that our loggers will meet the accuracy figures specified on our datasheets at the point of purchase.

Calibration Points

Our standard calibration points, which are used unless otherwise specified, are:
• Temperature: 0 and 30°C
• Humidity: 20 and 80 % RH (at 25°C)

These points have been chosen to give good coverage for general purpose use, but should other points be required we can calibrate units within the following ranges:
• Temperature: -20 to +150 °C
• Humidity: 20 to 90 % RH (at 25°C)

The thermistor probe range includes different designs, specifications and cables to meet varied demands. The range includes products for: temperature profiling; pipework monitoring; fridge and freezer monitoring; for use in composting and even armored units for process applications. Many are waterproof and dust-proof to IP68 making them suitable for damp, dirty or submerged locations.
