- Low-cost temperature with alarm indication or light intensity
- Waterproof housing for wet or underwater use
- Data readout in less than 30 seconds via fast Optic USB interface
A miniature, waterproof one-channel temperature data logger, this model is value-priced for short-term shipping applications or long-term deployment. Data logger alarm LEDs flash if temperatures have exceeded user-set levels and delay options, and provide visible verification that temperatures have been within the desired range throughout deployment.
The 64K model stores approx. 52K of 10-bit temperature readings.
The 8K model stores approx. 6,5K of 10-bit temperature readings.
For a complete system you’ll need:
Optical communication: BASE U-1
Data logger: Pendant
For accurate temperature measurement in sunlight a solar radiation shield is required (RS1 Solar Radiation Shield, assembly required; M-RSA pre-assembled Solar Radiation Shield).
