SL52T / SL52T-A Miniature Temperature data logger (-40°C to +85°C with up to ±0.12°C Accuracy)

SL52T / SL52T-A Miniature Temperature data logger (-40°C to +85°C with up to ±0.12°C Accuracy)

The SL52T is a self contained, multiple use, miniature temperature data logger with the ability to record up to 8,000 temperatures over the temperature range of -40°C to +85°C with an accuracy of ±0.5°C. 

The SL52T-A is supplied with a UKAS 17025 traceable calibration certificate and an improved accuracy of ±0.15°C over the range -20°C to +25°C.
Calibration tolerances up to ±0.12°C are available up on request.

Starter kits are available with either two or five SL52T or SL52T-A temperature data loggers, USB interface cable and the TempIT-PRO software.

The SL52T is ideal for use when sample rates faster than 5 minutes are required. For applications where sample rates of 5 minutes or longer are required, consider using the SL56T / SL56T-A

Starter kits are available with either two or five SL52T or SL52T-A miniature temperature data loggers, the USB Interface cable and the TempIT-PRO software: 

Being only 17mm in diameter and 6mm thick, the SL52T is an incredibly small temperature data logger. It is about the same size as a watch battery, which enables it to be inserted into small items and packages.

The memory can hold up to 8,000 readings and can be cleared at the start of each data logging session, allowing the data logger to be reused over and over. The memory can be set to stop logging when full so you don't lose those important first readings or wrap when full, throwing away the oldest readings once the memory is full and still storing new readings, to provide a rolling window.

The SL50-INTERFACE-USB interface lead is required to connect to the USB port of the computer and is compatible with the user friendly, and free of charge, TempIT-Lite operating software. This enables the logger to be set up and the readings downloaded from the data logger and displayed in a graphical format. Data can also be saved and retrieved at a later time. The software can be up-graded to TempIT-Pro which provides various additional features such as data table view, export data to spreadsheet, graph annotations, and automated MKT, F0, A0 and PU calculations.

 The USB Interface lead and software are not included with this miniature temperature data logger, unless your purchase the starter kit, but you can find details of these and other related items below.
