SL7104 Four Channel Data Logger

The SL7104 data logger has a very flexible combination of inputs that include internal temperature and 4 universal inputs each which means they can be individually configured with the software to accept any combination of the following input types: 

RTD / Pt100
Thermocouple (Types J, K, T, R, S, B, N) with isolated tip
Various Thermistors
Cu Sensors
Ni Sensors

The SL7104 data logger also has 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.

All SL7104 data loggers are supplied with a single computer licence of our TempIT-PRO software. Saving £135.00
