| ACCESSORIES for SMART3G-C2 gas detectors | |
| STS/CSW+ | Calibration software for SMART3G, SMART3NC, and SMART3R detectors consists of a USB key, a USB/RS485 converter, and an STS/IDI card. The software runs on Windows XP, Windows 7, and Windows 10. The calibration software allows you to modify the alarm thresholds and the measuring range and adjust the Zero, Span, and 4-20 mA values via a user-friendly menu, either in situ or in the laboratory. |
| STS/IDI | Plug-in RS485 interface to make SMART3G series gas detectors communicate in Modbus protocol with MULTISCAN++S1 & S2, MULTISCAN 8+ & STPL4+D control panels. |
| STS/CKD+ | Enhanced calibration keypad with 7-digit display and SD-CARD slot. It can be connected to all SMART detectors to adjust the Zero, Span and 4-20 mA values. Via the SD-CARD, it is also possible to update the detector’s firmware (a feature not enabled on old SMART3G and NC detector) |
| STS/CKD-OLED | Enhanced calibration keypad with OLED display and SD-CARD slot. It can be connected to all SMART detectors to adjust the Zero, Span and 4-20 mA values. This version offers enhanced features like: – visualisation of the instantaneous concentration in graphic format; – possibility to monitor the detector trend and download the data stored in the SD-CARD – detector’s firmware update via SD-CARD (feature not enabled on old SMART3G and NC detector) |
