Gas Detection 39 Optical multi-analyte
meter with a sting in its tail The compact FireSting-PRO is a unique one-device solution for multiple analytes and sensor heads. It is a PC-controlled (USB) fi bre-optic multi-analyte meter, which can be combined with the complete sensor portfolio for optical O2
, pH, and temperature sensors from PyroScience.
Each of the 4 optical channels is freely confi gurable for several analytes and sensor types. These range from microsensors (50 µm tip) to robust probes (3 mm tip) and include diverse smart contactless sensor solutions (for measurements in closed systems / respirometry, microfl uidics and complex geometries), as well as sensors for different ranges (full and trace range O2
, pH ranges).
A precision Pt100 temperature sensor can be connected to the temperature port, enabling automatic zero noise and zero latency temperature compensation of the optical sensor measurements in samples with varying temperatures, even during high speed measurements.
The FireSting-PRO features improved ambient light suppression for applications at in situ light conditions, as well as smart measurement modes for a prolonged sensor lifetime. Several FireSting-PRO devices can be simply operated with a single PC in a single Pyro Workbench window, offering scalable fi bre-optic multi-parameter sensor systems with e.g. 8, 16, 32, or 64 channels. It has never been easier to measure important parameters in a single sample at high precision with maximum fl exibility concerning analyte, sensor format, measuring mode, and application range. These devices are also available as 1-channel and 2-channel version.

56131pr@reply-direct.com New two channel digital detector with digital interface –
for easy integration and precise measurements Analogue pyroelectric detectors from InfraTec have been used in a number of different customer applications for over 30 years. These have now been joined by a new range of digital pyroelectric detectors called PyrIQ. Alongside the 4-channel detector, InfraTec has also developed the LID-2322: a compensated 2-channel detector in the TO39 housing which is primarily intended for gas analysis devices.
The two-channel LID-2322 is ideal for mobile devices thanks to its small and compact housing and can also run on batteries. It is suitable for use in different applications, e.g. harsh environments, as the optional thermal compensation reduces the effect of external fl uctuations. The integrated I²C communication interface with up to 1 MHz enables the measured values to be read out immediately via a PC or microcontroller in a reliable, standardised manner. Apart from the power supply connections, only two additional connections are required for operation of the detector to allow it to be parameterised and read out. This keeps the external hardware requirements to a minimum and makes it much easier to integrate the detector into the application. Using the additional clock input makes it possible to synchronise the radiator and the detector clock, allowing highly precise signal evaluation with a stable frequency.
Like all detectors from InfraTec, the digital detector is based on lithium tantalate (LiTaO3) as sensor material. In contrast to other materials, LiTaO3 offers a good signal-to-noise ratio and high sensitivity without additional cooling or temperature stabilisation. All of the internal signal processing is carried out by an ASIC (application-specifi c integrated circuit). The signal generated by the pyroelectric elements is amplifi ed in this circuit and then digitised with a
16-bit A/D converter. In contrast to analogue detectors, this allows the detector parameters to be fl exibly confi gured in order to optimise the signal processing. The spatial concentration and shielding of the entire signal conversion of the detector offer improved electromagnetic compatibility (EMC). Another special feature is the “fast recovery after saturation” function. This function detects the override due to a defective operating status or external override and automatically resets the analogue input stage within a few milliseconds. This signifi cantly reduces the time it takes for a measuring system to be ready for use again after starting or after temperature changes.
All in all, the LID-2322 offers excellent fl exibility and functionality combined with easy system integration in the standard TO39 housing.
