The InTemp CX703 Cryogenic data logger is a low-cost Bluetooth Low Energy (BLE)-enabled multiple-use logger that records temperature data for up to 365 days. The CX703’s built-in 1.5m probe measures temperatures as low as -200°C (-328°F) and includes a protective sheath to prevent accidental cutting of the cable.

Using the InTemp® app on your mobile device, you can easily configure the CX703 with one of multiple preset configurations, or set up a custom configuration. The logger has a built-in alarm to alert you to excursions. And logger reports can be quickly downloaded to your phone or tablet and uploaded to an InTempConnect® account, where you can analyze and export data as needed.

With the optional CX Gateway, you can get real-time notification of temperature excursions and automatically download data from loggers within range of the device. Learn more about the CX Gateway here.

Temperature Probe

Sensor Range:-200° to 50°C (-328° to 122°F); To ensure insulation integrity, avoid flexing the wire during exposure to temperatures below -100°C (-148°F)

Accuracy:

±1.5°C from -95° to -40°C (±2.7°F from -139° to -40°F)

±1.0°C from -40° to -10°C (±1.8°F from -40° to 14°F)

±0.5°C from -10° to 50°C (±0.9°F from -14° to 122°F)

Resolution:0.013°C at 25°C (0.023°F at 77°F)

Drift:<0.1°C (0.18°F) per year

Response Time:1 minute 30 seconds typical to 90% in open air moving 1 m/s, unmounted

NIST Calibration:

CX702 and CX703: Single-point NIST calibration, probe only

CX703-UN: Calibration not included

Cable Length:1.5 m (4.92 ft)
