Sensors: every parameter we can measure
XiltriX measures temperature from -200 °C to +250 °C, CO₂, O₂, humidity, differential pressure, particles, LN₂ level, door status, air flow, VOC, H₂O₂, light and shaking motion. Sensors are chosen per device, not per catalogue page, and several were designed by us to fit specific benchtop incubators.

Temperature
A wide range of PT100 sensors covers -200 °C to +250 °C. Form factors exist for cryogenic vessels, incubators, refrigerators, freezers, ultra-low freezers, ovens and surfaces such as heated microscope stages. For higher temperatures, for example muffle furnaces, thermocouples are used instead.
XiltriX designed dedicated temperature probes for benchtop incubators, including the Esco Miri and Miri TL, CooperSurgical G185 and G210+, Merck Geri and Origio BT37. They sit where the sample sits, not where the cable happens to reach.
Surface temperature is the parameter most often measured badly. Placement, contact pressure and thermal mass matter more than probe accuracy on the datasheet.
CO₂ and O₂
CO₂ is vital wherever living cells are grown, because it holds the pH of the medium. All XiltriX CO₂ sensors use dual-beam infrared measurement, which is stable in the high humidity found inside an incubator. Options run from a single sensor in one incubator to the 16-channel CO₂ monitoring station with automatic sampling and calibration.
Oxygen is measured either as a room condition, for health and safety in cryogenic areas, or as a growth condition inside triple-gas incubators running low O₂. The O₂ sensors carry two independent alarm relays, so booster fans or a local siren can be wired in on top of the XiltriX chain.
Adapters exist for the CooperSurgical G185 and G210+ so a gas sample can be taken without disturbing the chamber.
Pressure, humidity and particles
| Parameter | Range and accuracy | Typical use |
|---|---|---|
| Differential pressure | -1000 Pa to +1000 Pa, selectable, down to ±1 Pa | Cleanroom cascades, isolators, airlocks |
| Relative humidity | Wall-mounted, in-chamber and splash-resistant models | CO₂ incubators, climate chambers, cleanrooms |
| Particle counting | Digital integration with Lighthouse Apex R5 and R5P | Cleanrooms and biosafety areas |
Pressure transmitters come with or without display and with optional local alarm, in build-up or flush-mounted versions. Particle counters are available with an internal pump or connected to a central vacuum system.
Door, flow, VOC and safety parameters
- Door sensors, with a mounting plate that bridges the gasket gap, so an incubator or fridge left open becomes an alarm rather than a discovery.
- Air flow sensors for ducts, laminar flow hoods and biological safety cabinets.
- Conductivity sensors for water purity in tanks and demineralised water lines, down to very low µS values.
- VOC sensors with LED display, for pollutants in lab air that can harm living cells.
- Shaking sensors, an independent check that a thrombocyte agitator is genuinely still moving.
- H₂O₂ measurement during fumigation, in an air-tight case with integrated temperature and humidity, read wirelessly by a Telesto station.
- Light (lux) sensors for animal facilities, where light intensity and circadian rhythm are a legal obligation.
- Power failure, monitored by every station as standard.
How the sensor set is chosen
A XiltriX consultant walks the lab with you, lists the equipment that carries risk, and decides per device what has to be measured and where the probe belongs. That survey, not a price list, produces the sensor set. It is the same survey that later feeds the validation documentation.
