SL7104 Four Channel Data Logger
The SL7104 Data Logger provides a highly flexible combination of inputs, including an internal temperature sensor and four universal inputs. Each channel can be individually configured via software to accept any combination of the following input types:
- RTD / Pt100
- Thermocouple (Types J, K, T, R, S, B, N) with isolated tip
- 4/20mA
- 0–10VDC
- ±100mV
- Various Thermistors
- Slidewire
- Cu Sensors
- Ni Sensors
Additionally, the SL7104 includes a digital input that 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 license of the TempIT-PRO software, providing a saving of £135.00.
