The SL7000 data loggers have a very flexible combination of inputs from a single temperature up to 4 universal inputs each of which can be individually configured to accept any combination of the following input types:

• RTD / Pt100
• Thermocouple (Types J, K, T, R, S, B, N)
• mA (4-20mA 4/20mA)
• Volts
• mV
• Thermistors
• Slidewire
• Cu
• Ni

All SL7000 data loggers have an internal temperature sensor and a digital input which can be used as a trigger to start logging or as a pulse counter for interfacing with flow meters or other sensors with a pulse output.

An optional internal relative humidity sensor with ±2% accuracy is available on all units as well as an optional external temperature and relative humidity sensor. This gives a total of 9 channels - internal temperature, internal pulse counter, internal relative humidity, external temperature & relative humidity and either two or four universal inputs.

All SL7000 series data loggers are powered by their own, user replaceable battery, that has a typical life in excess of 6 years. Each SL7000 has enough memory to record up to 62,000 readings and the four universal channel data loggers can take 128,000 readings, at intervals from 1 second to 24 hours . Each data logger can be programmed to stop logging when the memory is full or over write the oldest reading.

The SL7000 features unprecedented accuracy, combining our extensive knowledge of instrumentation precision with data logging technology. High end resolution of 16 Bit for all universal inputs and a modular build ensures that the unit is competitively priced whatever the application.

An optional on-board LCD display shows selected channel information and the integral LED displays provide immediate scanning and alarm status information.

The data logger can be set to start logging immediately, start on an event (either a trigger event or the exercising of an external digital input) or start with the application of an external magnet (provided). This feature enables loggers to be set up in advance of the mission by a supervisor and to be launched at the start of the journey / log period by an operator.
