The LogTag® UTREL30-16 is a multi-channel temperature logger specifically designed for applications requiring long-term monitoring of ultra-cold temperatures. It features an LCD display, external probes, large memory capacity, and USB connectivity for exporting data as PDF or Excel reports.
| Product Model | UTREL30-16. |
| External Sensor Measurement Range | -90°C to +40°C (-130°F to +104°F). |
| Operating Temperature Range | -30°C to +60°C (-22°F to +140°F) 0-99% RH (non-condensing) |
| Storage Temperature Range | 0°C to +40°C (32°F to +104°F). |
| Rated Temperature Resolution | Better than 0.1°C (0.2°F) for measurements -80°C to 10°C (-112°F to 50°F) Better than 0.2°C (0.4°F) for measurements 10°C to 20°C (50°F to 68°F) and -90°C to -80°C (-130°F to -112°F) Better than 0.3°C (0.5°F) for measurements 20°C to 30°C (68°F to 86°F) Better than 0.5°C (0.9°F) for measurements 30°C to 40°C (86°F to 104°F) LogTag Analyzer currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®. |
| Sensor Reaction Time | Typically less than 2 minutes(T90) in moving air (1m/s) for ST10S type |
| Rated Temperature Reading Accuracy | Better than ±0.5°C for -20°C to +10°C (-4°F to 50°F) Better than ±0.7°C for -50°C to -20°C (-58°F to -4°F) and +10°C to +30°C (50°F to 86°F) Better than ±1°C for -80°C to -50°C (-112°F to -58°F ) and +30°C to +40°C (86°F to 104°F) Better than ±1.8°C for -90°C to -80°C (-130°F to -112°F) |
| Probe Connectivity | Up to 2 |
| Probe Compatibility | All ST10 precision thermistor external probes can be interchangeably connected to the UTREL30-16. Please refer to the Accessories section for compatible External Probes. Different probe models can be used for each channel. Not compatible with ST100 sensors. |
| Recording Capacity | 32,000 total log memory. Provides 16,000 temperature readings per channel. Day summary statistics memory (for display on LCD): up to 30 days of Min/Max/duration and alarm trigger statistics. |
| Sampling Interval | Configurable from 30 seconds to 18 hours. (Typically 5 minute logging) |
| Alarms | Up to 6 configurable alarms for each channel. Possible to set alarm separately for Channel 1 and Channel 2. |
| Logging Start Options | Push button start (with configurable start delay from 1 minute to 72 hours) or specific date & time. |
| Download Time | Typically with full memory (32,000 readings) in less than 20 seconds. |
| Environmental | IP61 (when vertically mounted or hung with USB dust-cap in place). |
| Power Source | 5V via micro USB socket or 2 x 1.5V AAA batteries. CR2032 LiMnO2 coin cell (backup logging function only). |
