Description
The 56-TR-74UI-S is the high-precision model of the 4-in-1 logger 56-TR-74UI — the same combination of light, UV, temperature, and humidity, but featuring the included SHA-3151 high-precision sensor, which provides a wider measuring range (-25 to +70 °C, 0–99 %RH) and ±2.5 %RH accuracy in the 15–35 °C / 30–80 %RH range.
Chosen for conservation environments with strict accuracy requirements — museums and archives adhering to international conservation standards (CCI, ICOM), clinical research where both light and climate must be documented with precision, and GMP-validated processes involving light exposure.
Features
- 4 channels: light, UV, temperature, humidity
- Light range: 0.01 lx to 130 klx
- UV range: 0 to 30 mW/cm²
- T/RH with high-precision SHA-3151: -25 to +70 °C / 0 to 99 %RH
- T/RH accuracy: ±0.3 °C / ±2.5 %RH (at 15–35 °C, 30–80 %RH)
- Cumulative light and UV exposure
- 8,000 data point memory
- Powered by 1 × AA battery for approx. 6 months
