One probe library,
every QC digital recorder.
Fourteen interchangeable digital probes and 4–20 mA transmitters that cover the parameters every regulated facility monitors — temperature from −200 °C cryo to +700 °C industrial, humidity, CO₂, O₂, differential pressure, and light. Calibration coefficients live on the probe itself, so a sensor swap is never a re-validation.
Probe → Recorder → MySirius. Traceable end-to-end.
A Digital Sensor stores its own calibration coefficients in onboard memory. The recorder reads them on connection, applies them in firmware, and ships the corrected reading to MySirius — every record stamped with the probe serial that produced it.
Digital Probe
Digital Sensors and probes carry their own calibration coefficients onboard. Swap a probe between recorders and the calibration travels with it.
SPY Digital Recorder
Nova, Nano, or LoRa SPY Digital reads the probe's coefficients on connect, applies them in firmware, and broadcasts the corrected value over the QC network.
MySirius
Each measurement is stamped with the probe serial and the coefficient set in force at the time — every record reconstructable on audit, even years after a probe was swapped.
Eight probes, six transmitters, one signal chain.
Two families share a digital backbone: Digital Sensors (cal-on-probe, plug into any SPY Digital recorder) and 4–20 mA transmitters (wall-mount, gas / pressure / light, connect through a Nano SPY U or LoRa SPY U).
Group 01 Digital Sensors
Direct-plug digital probes — calibration coefficients written into onboard memory, swap traceable mid-mission.
Digital Sensor T°Temperature probe · Ø7 × 25 mm · 3 m PFA
The everyday digital probe — ±0.20 °C accuracy with calibration coefficients stored on board for swap-in-place validation.
(−40…+50 °C)
Digital Sensor T° ShortCompact temperature probe
Same digital protocol as the standard T°, in a short-shaft body for tight fittings and faster response.
(−40…+50 °C)
Digital Sensor Low TemperatureUltra-low temperature probe
Built for the cold chain extreme — down to −200 °C for ULT freezers, LN₂ tanks and cryoconservation.
Digital Sensor THTemperature & humidity probe
One digital cable, two channels — temperature and relative humidity through a single connector.
Digital Sensor ReferenceHigh-precision PT100 reference probe
For mapping campaigns and on-site validation — PT100 reference accuracy with EN 15140 response time.
Short Digital Sensor ReferenceCompact reference probe
A reference-grade probe in a fast-response, short-shaft body — slips into smaller chambers and small-volume containers.
Digital Sensor StandardProfessional calibration-bench probe
For the metrology lab — −196 °C to +180 °C full span for cross-calibration of recorders, other probes and third-party hardware.
PT100 High Temperature ProbeIndustrial & pharmaceutical
Built for autoclaves, ovens and sterilization tunnels — up to +700 °C through a hardened cable gland and ceramic head.
Group 02 Transmitters
Wall-mount 4–20 mA front-ends for the parameters a probe alone can't capture — gas, light and differential pressure. Connect through a Nano SPY U or LoRa SPY U.
Ambient TH Precision TransmitterWall-mount T° + RH
For HVAC, food and pharmaceutical rooms — temperature and humidity in a single wall-mount unit with a local display.
Industrial Precision TH TransmitterRemote-probe TH for harsh environments
A wall transmitter with a remote stainless probe on armored cable — −100 to +200 °C for steam tunnels, dryers and process loops.
CO₂ Transmitter0–20% CO₂ NDIR
Made for the CO₂ incubator — NDIR optical measurement 0–20 %, drift-stable for long missions.
O₂ Transmitter0–25% oxygen volume
For LN₂ storage rooms and cryoconservation cells — oxygen displacement alarm as a life-safety layer.
ΔP TransmitterDifferential pressure for clean rooms
Cleanroom cascades, isolators and BSCs — 30 / 50 / 100 Pa ranges, <20 ms response, 4–20 mA out.
Lux TransmitterLight intensity measurement
A cosine-corrected light sensor for storage areas, inspection booths and stability chambers — photometric lux output, 4–20 mA.
One probe protocol.
Three data recorders.
Every Digital Sensor and PT100 probe in the catalog plugs into any of the three SPY Digital recorders. Pick the recorder for the form factor — the probe stays the same, and so does the calibration history.
When a probe gets recalibrated mid-mission, can your monitoring history prove which coefficient set produced each historical record?Run Your REM Risk Assessment
One library — three deployment options.
The digital probes are the same on every SPY Digital recorder. The choice between Nova, Nano and LoRa is about form factor and range. Compare side-by-side before you spec a fleet.
