June 22, 2011 – Servomex upgrades SERVOTOUGH SpectraExact photometric analyser. The Version D SpectraExact offers digital communications options, upgraded safety certifications and refinements to the SpectraExact’s capabilities. Digital communication options enable the full functionality of the SpectraExact to be controlled remotely and safely, with Modbus implemented through a choice of MODBUS RTU or MODBUS TCP/IP (Ethernet) protocols. A High Integrity cell option is now available, supplied with specialist chemraz “O” rings to ensure improved leak tightness for use in high concentration, highly toxic gas measurements. Available in one, two, four and eight millimetre pathlengths, the High Integrity cell further enhances the measurement flexibility of the analyser.
Meanwhile a Steam Heated cell is now a standard option and available on the safe area, IEC Ex and ATEX variants. Gas and dust certifications ensure the SpectraExact remains suitable for a wide range of dangerous environments. IEC Ex certifications have been granted for use in Zone 2 and Zone 1 gas and Zone 21 dust environments, as well as ATEX Cat 3 (Zone 2) and Cat 2 (Zone 1) certification to cover both gas and dust environments. A number of design improvements have also been made to increase the efficiency of the SpectraExact, including improved cell heater connector integrity, improvements to the EMC assembly and redesign of the external AC filter unit. All these features combine to improve the flexibility and further enhance the reliability and resilience of the analyser.
